HISTORY OF MCWM

The Clark Special Economic Zone (CSEZ), located some 80 kilometers north of Metro

Manila, Philippines is comprised of a 4,400-hectare Main Zone and a 29,213-hectare Sub-

Zone. Currently, it is being developed into a model metropolis built around the Diosdado

Macapagal International Airport.

Its master plan has provided Clark‘s reconstruction as a residential neighborhood,

mixed-use business district, recreational and entertainment center, support and aviation-

related facility, parkway and rail link, industrial estate and the site of a world-class

international airport.

The Clark Development Corporation (CDC), a government agency tasked to manage

the Zone, solicited proposals from various waste management companies for the handling of

the solid waste generated by its locators companies. The bidding was won by a German

Consortium composed of Birkhahn Nolte GmbH and Heers & Brockstedt Umwelttechnik

GmbH.

The German Consortium later formed the company ―Metro Clark Waste Management

Corporation‖ (MCWM) wherein 30% is owned by the Germans and the remaining 70% is

owned by various Filipino investors. The contract basically calls for the establishment of an

integrated waste management facility, to be operated for twenty-five (25) years, with focus on

landfilling for final disposal.

Some highlights of the integrated waste management center are the following:

II. SERVICE OFFERED

Metro Clark Waste Management Corporation provides, promotes and maintains

environmentally responsible practices of waste disposal. The object of their service is to

benefit their customers, consumers, employees, communities and the environment by doing

the business in ways that protect and demonstrate good stewardship of the world‘s natural

resources. Also, MCWM continually seek new ways to address the environmental cost and

impact of their landfilling activities, products and services.

MCWM is dedicated to developing sustainable solutions for minimizing the

environmental impact of urban development and energy production projects. Our team works

both in Europe and Middle East to develop Clean Development Mechanism projects and

reduce greenhouse gas emissions and saving energy.

6 | P a g e

As a landfill, MCWM produces by-products such as leachate and methane gas. For

this matter, the business provided a Leachate Treatment Pond to monitor and treat that

unwanted by-product so as to avoid any environmental impacts. With regards to the methane

gas which could be a source of energy, MCWM, on 2011 installed a methane gas collector.

However, upon the company‘s assessments, the amount of gas being collected is not enough

to build a power plant.

WHO ARE ALLOWED TO DISPOSE IN THE LANDFILL?

Every private or legal person is allowed to deliver recycling residuals, processing or

treatment residuals and Municipal Solid Waste (MSW) to the facility assuming they follow all

legal procedurals as required in RA 9003 and accept MCWM‘s terms and conditions for the

disposal of waste.

The disposal facility at Sitio Kalangitan, Clark Special Economic Zone, is a Sanitary

Landfill as stated under the ―Ecological Solid Waste Management Act‖, RA 9003 and is

permitted through the DENR by ECC 0012-704-213.

The ECC states specifically that all kinds of waste are allowed to be disposed in the

landfill except ―liquid, hazardous and medical waste‖.

The ECC has also several governmental resolutions showing that the sanitary landfill

is allowed to accept waste from all over the Philippines.

completed. Subsequent cells to be constructed will be anywhere from 3 to 10 hectares each,

depending on the demand.

Step by Step Waste Disposal

1. Entering on a Contract with MWCM

Obtaining a contract allows the waste generator to dispose waste to the facility.

Some of the requirements for entering into a contract with MCWM are listed.

PEZA Certificate of Registration as Waste Hauler/Collector wherein

MCWM is stated as Final Disposal Site (certificate may follow for new

PEZA applicants upon its release)

Latest OR/CR of Authorized Transport Vehicle

Proof of Training on Waste Management under PEZA

2. Getting a Gate/Yard Pass

The delivery truck comes in the premise of the facility and obtain a Gate/Yard

pass. This is for tracking purposes.

3. Inspection

Contents of the hauler will be inspected to ensure that only the required waste will

be disposed in the facility.

4. Initial Weighing

The hauler/waste generator will pass through a weigh bridge. This will determine

the initial weight of the truck, that is the weight of the empty truck plus the weight of the

waste to be disposed.

5. Waste Disposal

After the type and amount of waste determination, the hauler/truck will then go to

the designated land fill area for that specific type of waste to dispose its contents. From

this point, heavy equipment machinery will facilitate to the proper land filling. That is, the

wastes will be compressed until a cell is completed. Compression of the wastes is in a

ladderized manner called benching to provide a sturdier structure. After compression, the

compacted waste will be flattened and then will be covered with clay.

13 | P a g e

The landfill is well designed in such a way that no leachate will harm or

contaminate the groundwater. This is by using multilayered protective materials which

prevent leachate form passing through the soil thus avoiding the contamination of the

water reserves underground and a HDPE tube which sends the leachate to the Leachate

Treatment Plant. A more detailed description of the landfill can be read in the quality

control part of the text.

Solid Wastes Disposal

Compression of the Solid Wastes

14 | P a g e

6. Washing

Washing of the truck will come next after the disposal. The wash water will be

directed into a pond where it will be treated. This step of the whole disposal process

assures the safety of the community surrounding the facility.

7. Final Truck Weighing

Another truck weighing will be employed after the washing step. This would

monitor the amount of waste being disposed (it can be computed by subtracting the weight

of the truck after washing to the initial weight of the truck) and thus, would allow the

determination of the disposal fee. The disposal fee is listed in the table.

15 | P a g e

QUALITY CONTROL PROCEDURES

In order to provide the best quality service they can give, MCWM has the following to

control their process. These are:

1. Facilities

2. Strict Requirements for Disposal

3. Sanitary Landfill that Exceeds the Standards stipulated by RA 9003

Facilities

Some highlights in MCWM‘s integrated waste management center that could help

maintain the quality of their service are:

Entrance station with weigh bridge

Before entering the premise, waste generators must first obtain a gate

pass. This would allow MCWM to record and track all that are being

input in the facility.

Leachate storage and treatment ponds

Before disposing waste water in the environment, all are first treated.

To ensure that the effluent comply with the standard, tests are done

quarterly by the government. Some of the parameters being tested are

the Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand

(COD) and color.

Environmental buffer zones / re-greening zones

Their environmental buffer zone is designed to monitor the safety of

the operation. This serves as an indicator whether their effluents,

specially the air, comply with the standards.

Administrative buildings

This would cater the needs for management functions.

Materials recovery facility (MRF)

The MRF would allow reusable materials to be recovered, thus

decreasing the amount of waste being disposed in the landfill.

16 | P a g e

Workshop

Workshops would help employees to understand more the rationale of

the operations being done. Understanding every aspect of the operation

would result to a more quality service.

Runoff water collection system

Retention basins

Recycling and waste treatment facilities

Strict Requirements for Disposal

Standard requirement for sludge and ashes which are out of industrial processing is the

TCLP analysis (US EPD Standard); it has to be within the described TCLP limits and

so far as necessary DENR confirmation as ―non-hazardous‖. Asbestos has to be

certified as NON-FRIABLE.

The waste generator has to provide MCWM with test results before finalization of

the disposal contract.

MCWM will conduct ―backup‖ analytics on site for each delivered charge. If a charge

fails the limits or shows total different consistency of the delivered materials, MCWM

will have the right to reject the charge.

Furthermore, MCWM has the right to require additional tests, if necessary, to insure

that no hazardous materials are disposed in their facility.

MCWM has the right to reject charges due to operational reasons.

MCWM will provide the Generator / Hauler with a ―Certificate of Final Disposal‖ /

―Letter of Destruction‖ in accordance to RA 9003.

Sanitary Landfill that Exceeds the Standards stipulated by RA 9003

The SANITARY LANDFILL (SLF) in Sub Zone D, Clark Special Economic Zone,

Sitio Kalangitan, is build based on international accepted standards, which exceed the

standards as stipulated in RA 9003 substantially.

The protection layer which insures that no liquids (leachate) from the landfill could

harm the soil or the groundwater is basically based on a redundant liner system out of natural

and artificial materials with extreme low permeability. Further the local geology with very

dense clay material protect the groundwater, which can be found in the area of the landfill

about 60m below the surface.

T

he

technical protection layers are built out of a 0.75 m thick clay liner (implemented highly

compacted) and a 2.5 mm HDPE (high density polyethylene) plastic liner. An additional layer

of geotextile is placed to protect the HDPE from sharp wastes.

Baby Landfill Showing the Parts of the Engineered Design of the Facility

18 | P a g e

MCWM opted to use German technology manufacturing and installation of the

HDPE liners.

The drainage system for the leachate is built out of a HDPE pipe system (which can

sustain more than 80m waste load) and a real gravel filter, which would insure that all

incoming leachate could be forwarded to the Leachate Treatment Plant. The pipe is spiral in

shape so as to ensure that the said pipe will not be destroyed easily.

The temporary Leachate Treatment Plant for the phases 1 + 2 is built as a ration

ponds with the additional utilization of specialized enzymes for the complete cleaning of the

water. Further filtration through a ‗reed bed‘ is planned.

19 | P a g e

IV. ENVIRONMENTAL ASPECT

WATER TREATMENT

Since Metro Clark Waste Management Corporation is an engineered sanitary landfill,

the only water they are to treat is the leachate produced by the solid wastes and the water used

for washing the trucks of waste generators who dispose in the facility. The leachate are

collected by the Drainage System installed in the landfill and are directed to the Leachate

Treatment Plant. The wash water are also directed to the said plant.

In the plant are ration ponds where specialized enzymes are utilized for treatment of

water. Aeration is also employed to increase the dissolved oxygen in the water. After that, the

water will pass through an adsorption reed bed where fibers of soft broom are placed plus a

secret ingredient discovered by their research team. After that, the water will pass through a

phytofacultative pond where in heavy metals are removed by water lilies.

ENERGY SOURCE

The energy of MCWM is being supplied by MERALCO.

WASTE TREATMENT

Metro Clark Waste Management Corporation provides a sanitary landfill for all

around the Philippines who comply with the requirements of RA 9003. The solid waste they

generate are being landfilled, the water are treated in the Leachate Treatment Plant and air

wastes are treated naturally, in the environmental buffer zone of the facility.
