Over the last few decades accelera-
ting environmental concern which,in some countries, has alre a d yresulted in legislation, and financialinterests in the re-use of products,p a rts or materials, have allcontributed to reverse logisticsrecent popularity. In a broad sense,reverse logistics stands for all
operations related to the re-use ofp roducts and materials. Reverselogistic activities include collec-tion, disassembly and processing of
used products, product part s ,and/or materials, in order to ensurea new use or an environmentally
friendly recovery. From a scientificpoint of view, reverse logisticsbringsnew elements in collec-t i o n / d i s t r i b u t i o n m a n a g e m e n t ,production planning/rem anu fa ct u-ring, and inventory contro l .Besides, there are interesting
relations with business economics,e n v i ronmental management andinformation technology.
In this paper, we focus ourattention on the relation betweenreverse logistics activities andi n f ormation technology with the
objective to examine and evaluateexisting applications ofE-commercein this field. At large, E-commerceis defined as sharing businessinformation, maintaining businessrelationships, operating businessnegotiations, settling and executing
agreements by means of telecom-munication networks, often the
I n t e rnet, in order to achievebusiness transactions [adaptedfrom EITO99 and Zwass96]. In light
of the reverse logistics context,
E-commerce is examined in terms,trading of used products and parts,including marketing, purc h a s i n g ,sales and post sales. Also, weexamine systems that can facilitatedata collection for used products atthe collection stage and IT applica-tions to support remanufacturing
and re-distribution activities. It isworth mentioning that although bydefinition E-commerce is inclusivefor all electronic networks, the
focus of our study will be onInternet-based E-commerce for twomain reasons. First, the penetration
of Internet-based E-commerc ei n c reases drastically, while asignificant portion of EDI usersintends to switch over to Internet-based applications [EITO99]. Inaddition, many of the actorsinvolved in reverse logistics
activities may not be able to haveaccess to an EDI infrastru c t u re .
Within this context, there are veryfew references of E-commerce forreverse logistics activities, except[Lee 1997] who presents a specificapplication for the electronic auc-
tioning of used Japanese cars.Moreover, many researchers exami-ned various aspects of electronicmarketplaces [Bakos 1997, Beam1999, Bichler 1999, Dutta 1998,Gebauer 1995, Klein 1997] inwhich used products are sold along
with new ones, without explicitlyconsidering the reverse logistics
perspective. Thus, it is interestingto identify what kind of electronicmarkets are related to reverse

logistic activities and how one can
assess their risks and benefits. Weare also interested to examine the
relationship between E-commerce
and the economic aspects of
markets. For example, E-commercepotentials have been very carefully
examined with respect to certain
markets, which traditionally have
not been functioning in a very effi-
cient way through the traditionaldistribution channels [Wrigley
1997, Klein 1997]. Could, in fact,
E-commerce create a homoge-
neous, electronic market for used
products and parts open to all
interested parties? And if so, what
would be the critical factors for
the successful implementation of
such an electronic marketplace? Inview of such developments and
potentials, it is also interesting
to examine how existing Web
applications and other IT technolo-
gy can promote other reverse
logistics activities and identify
what (if any) E-commerce promi-
sing, yet under-deployed potentialexists. For example, could Web
applications be used to decrease
some of the uncertainty encounte-
red in reverse logistic activities
in some cases? Are there some otherdevelopments towards this direc-
tion and how do they compare?
In our study a series of relevant
sites have been selected and
examined based on specific criteria
with the aim to identify how they
function and how efficient they are.
Based on this, an evaluation of the
examined case studies is carried
out and some directions for future
research and development haveemerged. These are the main
directions of this paper, which isstructured as follows. In Section 2,
we review reverse logistics
activities and their relation to
Information Technology. First, we
identify important aspects that
have not yet been addressed
adequately from the InformationTechnology point of view. Then, we
proceed to examine how Internet
technologies can support some
aspects of reverse logistics,
focusing on those, which although
not directly related to a businesstransaction, are still very important
for an efficient operation of
a reverse logistics network.
In Section 3, we examine three mainE-commerce models that facilitatebusiness transactions for reverse
logistics, we assess them and give anumber of illustrative examples. An
overall view, some directions forfuture research and development,as well as some speculations about
future deployment of E-commercewith respect to reverse logistics aresummarized in Section 4.
REVERSE LOGISTICS ACTIVI TIESAN D SUPPORTING IT SYSTEM S
The main objective of this sectionis to describe what the mainreverse logistics activities are andhow Information Technologysupports and facilitates theseactivities. The description is mainlytaken from several overviews onreverse logistics [Stock 1998,Fleischmann 1997, 1999 and
Thierry 1997].
Descript ion of ReverseLogistics and open issues
Figure 1 presents a graphical repre-sentation of the activities within aproduct recovery chain together
with traditional supply chain activi-ties. The recurrent reverse logisticsactivities include collection, inspec-tion/separation, re-use, remanufac-turing, recycling, re-distributionand disposal.
In Figure 1, the main concept is that
products are brought to the market
through some conventional supply
chain. The majority of products is
used in their original functionality:
i.e. a company buys a state of theart computer for their virtual
reality project. After a while, the
product is not useful to the original
user. In our example, the industry
standards have evolved and that
computer can no longer support
them. Frequently, the product is
traded in a marked down price
once or several times. In our figure,
this is denoted by the loop between
original use and trade. It is worth
to point out that through the
repetitive changes of ownership,
the product is still used in
its original functionality. In our
example, the computer might be
bought for personal use or for
entertainment, before it actually
reaches the end-of-use return flow.
The main idea for reverse logistics
is to promote and support alterna-
tive uses for the product. In our
example, the computers keyboard
could be directly re-used, its
motherboard may be remanufactu-
red in an electronic toy, whereas
other parts (casing) could berecycled.

Inany event, with new or old func-tionality the product (or parts of it)enters the market again whereit may also go through severaltrading cycles. This concept isdenoted by the closed loop
between other use and trade inFigure 1. Certainly, at some futurepoint in time, the product will reachagain the end-of-use return in thereverse logistics network.
Supply, manufacturing, distributionand their cascading flows representthe traditional supply chain.From the reverse perspective, theflows for production waste andc o m m e rcial re t u rns are veryimportant, because these two com-bined with the end-of-use return
flow are all input flows in therecovery chain. Production wasteincludes the remains of rawmaterials / intermediates that islost in the production, i.e. a part ofsteel sheet that is too small to beused in the manufacturing of aproduct, and the side products thatcome free during production. Acommercial return would be anyunsold product that a supplier hasagreed to take back from the retailc u s t o m e r. Wa rranty re t u rns offailed products were not explicitly
mentioned in the picture, butshould be added to the commercialreturn stream if the products canno longer be repaired. The sameholds for all perishable productswhich can no longer be sold. Anend-of-use return, as explained inour example, is either the turn-in ofa product to the seller/OEM, becau-se its use has been terminated andthe seller is forced to take it back,or the collection of the product bya waste collector.
The first stage in the reverselogistic process is collection, thatis, all those activities that arenecessary for reclaiming returnedproducts, surplus or by-productsand transporting them to a place,where they will be subjected tof u rther examination and pro c e s-sing. Locating such products,p u rchasing, transporting themand storing them at a collectionpoint, are all activities related tocollection.
A major issue in collection is thee n c o u n t e red high uncert a i n t yregarding the locations from where
used products need to be collected,their quantity and timing.These pose severe difficulties inplaning and controlling collectionp rocesses. Furt h e rm o re, theseuncertainty factors are detrimental
to the integration of forward andreverse distribution networks,which is a very important issue ifwe consider that the additionaltransportation induced by returnflows is a negative element in theoverall ecological assessment ofindustrial re-use activities.
Another major issue for productsentering the reverse logistic chainis that of their quality. This issue iscentral at the stage of selection,w h e re a decision must be
reached as to whether a product(or parts of it) will be re -used, remanufactured, recycled ordisposed. Physical inspection isne ce s s ary ford e te rmining furthe rp rocessing for most commerc i a lp roducts. The alternative ofremote monitoring and contro l ,that are currently availablefor certain products (such ascomputing equipment and electro-nics) have not yet been employedto improve the reverse logisticsoperations.
Remanufacturing is a series ofsteps necessary to transform a partor product that has been used intoone that is usable again. Sometypical activities in re m anu fac tu-ring include cleaning, disassembly,replacement and re - a s s e m b l y.H o w e v e r, remanufacturing is sop roduct dependent that it canbarely be characterized by typicalactivities. For example, restorationfor a piece of old furniture mayre q u i re artistic skill , whereas
remanufacturing of a piece of heavyequipment re q u i res advancedindustrial infrastructure.
For remanufacturing an unresolvedissue is centered on decisionmaking for dismantling or dis-assembling a product. In general,dismantling everything up front is alabor-intensive task, while on theother end, on-demand dismantlingrequires extensive storage capaci-t y, has uncertain yields andvariable throughput times. For
many companies remanufacturingis a very sensitive issue. Re-proces-sing is so product specific that if a
third party is involved at this stage,in-depth information about aproduct can be easily gathered. Inthis respect this process is verysimilar to reverse engineering.
Thus, it is possible to pro v i d e
g rounds to product pirating,namely, to develop a new productbased on the technical specifica-tions derived from re-manufacturedproducts.
Re-use refers to cases wherere t u rned products have such agood quality that they can be re-used almost immediately in thesame or an alternative market. Thishappens for re-usable bottles,containers and most leased orrented equipment. It may also
happen for surplus goods, e.g.spare parts which are left over afterdiscarding the original equipment.
F i n a l l y, re-distribution refers tothe logistics activities required tointroduce a product into a market-place and transfer it to thec ust ome r. Obviously, this entailsstorage, sales and transportation.M o re o v e r, efficient marketing ofre-usable products re q u i res
protocols that support clear andconcise communication between
interested parties and mechanismsto facilitate matching offers withrequests.
Information Technology for
Rever se Logistics
Based on Figure 1, one can observethat information flows betweenbusiness partners are complemen-ta ry to the actual product flowt h rough supply and reversenetworks. This observation could
lead to the suggestion that informa-tion technology systems forreverse logistics can be prototypedbased on the systems developedfor the traditional supply chain.However, there is a fundamentald i ff e rence between forw a rd andreverse logistics, namely reve rs elogistics is in many situationsan exception-driven process. Inaddition, data for the itemsentering the re c o v ery chain are
often of poor quality. Thus, ad i ff e rent overall perspective is
re q u i red for developing re v e r s elogistics IT systems, as it wasnoted in Rogers 1998. However, it

is important to see what the infor-mation dependencies betweenforward and reverse chains areand how IT systems can givesupport. Summarized, in order tohandle reverse logistics efficiently,accurate and sufficient informationis required in addition to informa-tion systems that satisfy specificreverse logistics requirements.
Therefore, we examine three inter-related issues in the followingsubsections. First, it is importantto examine technologies thatpermit the collection of quality dataregarding a product entering thereverse logistics network. Secondly,it is interesting to address the issue
of interaction and informationexchange between forward andreverse logistics systems. Finally,some emerging Web applications,although not directly applicable atpresent, but which can have greatpotentials for reverse logisticssystems will be indicated as subjectfor future research.
Data Collection on ItemsEntering t he Reverse LogisticsChain
In general it is important to knowwhat product will be returned atwhich point in time at which place,in which conditions and underwhat grounds. More specifically,for commercial returns one shouldknow the as-perfect condition ofa product or part and how thereturned product measures to that.Also, for certain products that havehigh value and short life-cycle, it isvery important to examine whethera product returned to the point of
sale (POS) meets the allowed timeframe requirements. Finally, anaccurate explanation of the reasonwhy this particular product entersthe reverse logistics network canfacilitate the selection/inspectionphase.
Conventionally, product relatedinformation is recorded in paper-based catalogs, which presentcertain constraints: they areneither easily retrieved, frequentlyupdated nor can they be searched
in a speedy way. An alternativewill be the Electronic ProductCatalogues that can offer amultimedia representation of
product information as well asretrieval, classification servicesand instructions for handling upon a return. Another alternativewill be for that information to beembedded in the product. In fact,technologies such as two-dimensio-nal bar codes and radio frequencyidentification systems may be usedto support this feature. Two-dimen-sional bar coding allows the user toembed much more information in abar code than one-dimensionalsystems such as UPC. It supportsthe registration not only of a codebut also a description and othertextual data of significant capacity.Similar in concept, RadioFrequency Identification (RFID)
uses small, very low powered radiotransmitter that is installed in eachproduct. This tag can have somememory capacity for data storagebut it also broadcasts a signal in10M combinations, that is, it ispractically unique. The battery isstrong enough to send out a signalfor years and the signal is strongenough to be picked up byreceivers in a warehouse.
Information about end-of-use ret-urns can be improved by keeping
track of the installed base. Leasingforces the manufacturer to keepdetailed information about thestate of products. Hence followingthe product after its sale alsoprovides marketing opportunitiesto influence the return of theproducts.
The Interactivity Issue be tw eenForw ard a nd Reverse LogisticsIT systems
The need for co-ordination among
processes between forward andreverse logistics system alsoimposes a requirement for interac-tivity between the supporting
IT systems. Business processesbetween trading partners inthe forward supply chain havebeen supported by legacy EDIsystems and Value-Added Networks(VAN) for electronic transactionsand network configuration, respec-
tively. This relationship, oftendescribed as business-to-business
E-commerce and networkinginfrastructure, is also known asExtranet.
Electronic Data Interchange (EDI)allows trading partners to exchan-ge information electronically in avery compact, concise and preciseway and it provides different tran-saction sets for various typesof business activities. The "180
transaction set" is, in principle, thetransaction set that supports someaspects of reverse logistics.
However, in practice, it is seldomused. [Rogers 1998] contains a verydetailed presentation on this topic.EDI applications are based on
structured protocols, pre-establi-shed arrangements and bilateralinformation exchange; thus, atransaction supporting software

proves necessary. Conventional EDIhas been criticized for being expen-sive in terms of initial investmenton infrastructure, software andtraining. Furthermore, becauseof its structure, this arrang-ement establishes and supportscontinuous relationships betweenknown trading partners, thuscreating a closed-club kind ofelectronic marketplace.
Addressing these technical impedi-ments, the emerging standardXML/EDI provides the means forintegrating EDI applications withthe Web. Benefits resulting fromthis arrangement include lowercosts, easier introduction of newtrading partners and increasingcommercial activity. From a reverselogistics viewpoint, there is theadded benefit that XML/EDI can bethe tool for interacting IT systemsspecifically designed for reverselogistics and legacy EDI systemsthat are still in use in the forward
supply chain. Concluding, manydifferent types and platforms ofsystems may co-exist to servedifferent business needs, as shownin Figure 2.
Figure 2 presents three levelsof networking infrastructure.Firewalls may be implemented toprovide secure systems. Accessoriginating from an organizationoutside the protected area canbe denied if it violates securityauthorizations, whereas communi-
cation with trading partners(organizations that are locatedin the same ring) is supportedthrough the networking structure.
Emerging IT Paradigms forReverse Logistics
It is noteworthy that some existingInternet applications, although notdirectly related to reverse logistics,have quite promising potentials forthis area, as well. For example,several Internet-based applicationssupport aspects of mass-customi-zation in the sense that theyprovide interactivity to potential
customers who are interested inpurchasing products that areconfigured on the basis of theirown specifications (i.e. buying acomputer from www.dell.com).From a reverse logistics pointof view, it is worth noticing howeasily accurate information can becollected from an E-commerce
application regarding currentcustomers' needs on specialized,high-value products and theirfuture influence on the reversesupply chain; albeit privacy protec-ting should also be secured.
Moreover, there is a class ofexisting Internet-based applica-tions (i.e. www.firefly.com) thatcapture data on their members'behavior to classify their clienteleinto groups of customers withsimilar preferences. Upon an eventof interest (i.e. purchase of certainproducts by any member of agroup), the relevant data may alsobe used to promote the same itemsto the rest of the group with
an expected high degree of accep-tance. From a reverse logisticsperspective, such mechanismsenable interested parties to captureaccurate information on differentfragments of the market and identifypossible trends or price changes.
E-COM M ERCE AN D REVERSELOGISTICS
The general aspects of E-commercefor Reverse Logistics are summari-sed in Table 1, but not all of theseare equally represented.
So far, we have identified threeprominent e-commerce models forthe support of reverse logisticsactivities. At present, the mostpopular model for E-commerce forreverse logistics is ElectronicMarketplaces, which are used for

both new and used products. Then,there are sites that use the Web tooffer used parts or remanufacturedequipment. Finally, there is alsoa Web based paradigm that incor-porates collection, selection, re-use
and redistribution. These E-com-m e rce models are presented inFigure 3, which relates closely to Figure
1, but it concentrates on the reverse
logistics part, for simplicity reasons.
Electronic M arketplaces
A common feature of electro n icmarketplaces is the fact that theyare product-focused. Various usedproducts are for sale in these sitesand potential customers have achance to get relevant informationon them, declare their interest andpossibly buy them. The conceptand the design of an electronicmarketplace may vary gre a t l ydepending on a number of factors.We have examined sites based ongeographical location of theirservers, sectors represented in thesite, access rights, price determi-ning mechanisms, logistics aspects,and guarantees for customersatisfaction.
Geographical location of the WWW
server and its target market variesbut they have a high density overUSA sites, as expected. AlthoughUS-based electronic marketplaces(like www.ebay.com and www.onsa-le.com) have significant visibilityand coverage, they do not yetappear to be worldwide oriented;r a t h e r, they concentrate withinthe north American market dueto their demographics or to amanagerial decision to simplifyingtheir logistics operations. In EU,e l e c t ronic marketplaces may be
even more localized (www.partiku-lier.nl) having to overcome cultural,logistic, linguistic and monetarybarriers between different memberstates of the EU. In view ofthese, www.qxl.com offers differentcontents in its site for UK, France,Netherlands, Germany and Italyresidents.
A wide variety of products thathave entered the reverse logisticschain are traded, but some sectorslike computer, electronics and
hi-tech equipment are particularlyp opula r. Nonetheless, some elec-tronic marketplaces are vertically
s t ru c t u red, that is, they arededicated to a specific product likeused cars (AUCNET) [Lee 1997]or used industrial equipment(w w w. b e rg e r a t - m o n n o y e u r- t p . f r) .F u rt h e r, there is a significant
number of on-line marketplacesre p resenting all three types offlows entering the reverse logisticschain, namely production waste(w ww.m eta lsi t e.c o m), commerc i a lreturns (www. qxl.com) and end-of-use products (www.ebay. com).
There are some trading communi-ties open only to partners whohave established relations throughconventional interaction or wherenew members are introduced aftersome member's recommendation.
H o w e v e r, for most electronicauctions, access is open toall buyers, whereas sellers haveto register and pay fees. Aprice setting mechanism can beavailable online like in the case ofe l e c t ronic auctions(w w w. o n s a l e .com, www.qxl.com) or be subjectto interpersonal communicationt h rough conven-tional means(w w w. p a rt i c u l i e r. n l, w w w. c l a s s i-fieds2000.com).
Logistics aspects of electronic
marketplaces cover a great varietyof services including inventorymanagement, virtual warehousing,t r a n s p o rtation, scheduling androuting, location identification, setup and operational specifications.
To simplify the logistics operationsof the electronic marketplace,subcontracting third parties to dosome or all of the described logisticfunctions is a common tactic inmany electronic marketplaces
To address customer satisfaction, a
regulatory infrastructure or legisla-tion may apply. For example, theAucNet system [Lee 1997] providesa standardized rating system for thequality of items featured in thismarketplace. Thrusted ThirdP a rties (TTPs) play import a n ti n t e rmediate roles in case ofconflict between buyer and seller(e.g. if the goods delivered do notmeet the specifications). Otherpolicies for customer satisfactioninclude posting the seller's physicala d d ress, insurance coverage for
damaged goods, guarantee ofretu rns in case of unsatisfactoryitems etc.
E-commerce model forthe supply of used or
remanufactured parts orequipment
The main difference between sitesfor promotion of remanufacturedparts or equipment and those fornewly produced goods seems to
lie in the fact that the first arecustomer driven whereas thelatter are normally supplier driven.In the first case a potential customep rovides details for the itemsin request and the supplierperforms a search and provides theprocurement details. Based on thisorientation, two main characteris-tics emerge for this model. First,
E - c o m m e rce for supply of usedparts is region bounded, that is,suppliers usually serve a range ofparts or equipment over a more orless defined geographical region.As a case in point, Sears(www3.sears.com) covers only theUS territory.
Identification of the part in requestis a central issue to the success ofthis business process and it impliesthat both interesting partiesmanage to get in contact with eachother and then use a common,unique and unambiguous frame-work to describe requestedp roducts or parts. Nowadays,search engines on the Web maybe used to locate potentialsuppliers (w w w. f i n d - a - p a rt . c o m) ,while catalogues of spare part so ffer a unique coding system.Identification of a part canbe enhanced through oral commu-nication or through the use ofweb-accessible search engines that
are based on some prominent fea-tures of the part (brand, descrip-tion, code etc). However, the websites for supply of remanufacturedparts or equipment are mostly usedfor information dissemination andas such, they only address themarketing aspect of electroniccommerce.
It is also interesting to note thatdemand driven dis-assembly may
be possible, if a requested partis not directly available, but rather,
it is included as a subassemblyin a unit. Demand driven dis-assem-bly re q u i res a sufficiently large

i n v e n t o ry of used products tosatisfy demand and this is oftenperceived as costly.
A special case of remanufacturing
refers to preventive or re a c t i v e
maintenance for heavy industrial
equipment, which may operate
in geographically remote places
and under very stressful condi-
tions. Remanufacturing industrial
equipment is often a closed loop
process, in the sense that, users
give in a piece of their equipment
and some time later they get it back
re - m a n u f a c t u red. Severe time
constraints and quality guarantees
a re important factors for
remanufacturing.
U rgency is a determining factor,
when somebody tries to purchase
a part. In this respect, swift
completion of the required process
and logistics are very important
factors for customer satisfaction in
this trade. E-commerce thus plays
an important role in stimulating
re-use and remanufacturing of parts
or products.
E-comm erce for complet e
reverse logistics solutions
This model was rarely encountered
in our study. We believe this is due
to the fact that this model does not
view E-commerce as a migration of
existing practices and serv i c e s
over a new infrastru c t u re, but
rather as a new tool to restructure
a business activity and offer new
s e rvices. E-commerce complete
solutions for reverse logistics run
a c ross the reverse logistics
network in a particular industry/sector (i . e . p h a rmaceuticals for
w w w. re t u rn l o g i s t i c s . c o m) .
T h rough this model, customers
have two options. First, they can
describe their returns, request a
quote and upon agreement on the
price, sell their products. Or, they
may request a quote for an order
they plan to place.
It is interesting to note that re-use
of the re t u rns (which is the
current practice in this model) isless demanding than supporting
remanufacturing, for example. An
E - co mm erce model for complete
reverse logistics solutions that
could offer a combination of all
reverse logistics activities could be
a niche market by itself.
CONCLUSIVE REM ARKS
E-commerce for reverse logistics is
an area of web applications that
has been active and progressing
aggressively, especially in the US,
though it has not been explicitly
recognised until now. It has given
reverse logistics in general and
especially remanufacturing of parts
and re-use of surplus goods an
important stimulus. However, exis-
ting E-commerce models are rather
restricted and represent simply the
migration of conventionally prac-
tices over the Web. Therefore, we
expect further development in this
area and we believe there are many
interesting research issues in this
respect.
