W2W origins: P&G
P&G Sustainability Goals
Criteria for an Ecopark: P&G
Approaches that can handle a mix of both organic and inorganic waste and up to 65% moisture in the waste stream
Systems that have potential for technical and economical feasibility that could operate on a community/village scale in developing countries
Systems that will be simple, cost-effective and robust enough for developing countries (infrastructure and maintenance)
Systems that have moved beyond the pilot stage and are in commercial production and that that will be scalable
Approaches that have the potential to be environmentally “friendly”
Key Strategy: P&G
single technologies
Consumer-Facing Corporations
Sorting and Segregation
Recycling/Front End
Highly automated, generally high CAPEX

Overall Approach for W2W
We will create an economically, environmentally,
socially and technically sound business model
through construction of EcoParks that will:
• Take 100% of the municipal solid waste from a
community generating at least 225 tonnes MSW/day
• Eliminate the current municipal solid waste from going
to landfill (or being dumped or burned)
• Target to have zero waste to landfill for a community
• Significantly increase recycling in a community
• Produce jobs in local regions (for both the informal
waste sector and the local community)
• Produce up to 7 revenue streams from an EcoPark
• Be able to partner with the local and federal government to scale the model across the country
EcoPark OverviewA For-profit Business
• Food• Clean water• Housing• Healthcare• Education• Living wage
• Partnerships with Governments, NGOs, Corporates and other stakeholders
• Public-private-philanthropic partnerships
W2W FoundationA Not-For-Profit Company
Work in concert with stakeholders to enable the
waste picker community to have access to:

Water processing
• Locally managed and owned with local partner support and key experienced staff
• Site selection criteria: maximizes success based on existing learnings
• Modular and scalable: (225-250 T/D) “modules”
• Variability in input (moisture and organic content) adjusted for in the modules
• Simplicity in design allows for ease of use
• Technology selection: based on „best in class‟ for the selected design
• Long-term waste collection agreement with the city who
owns and manages collection (themselves or 3rd party)
• Use existing waste characterization data where
available – consistency and ensure across Wet/dry
seasons
Primary Outputs:• Energy (two streams): 46 million
kilowatt hours at average selling
price of $0.15
• Recycled materials (4 streams)
~$2M annually
• Soil amendment (1 stream)
Off-take:• Long-term agreements for energy
(electricity); focus on > $0.15/Kwh
• Standard recycling agreements
available everywhere
EcoPark Components
Segregation

• Wet Phase (high organic content) is well suited to high solids AD process
• Dry Phase (~20% moisture) is well suited for gasification process
• Commercially practiced today
Anaerobic Digestion
• Use the High Solids Process - matched to high solids content from VM Press
• Being commercially-practiced across the globe
• Many and varied manufacturers/suppliers (Harvest Power)
Thermal Conversion
• Use Concord Blue technology – matched to ~20% moisture content from VM press
• Practiced commercially in developed and developing world
Water Treatment
• Use Baleen International technology
• Practiced commercially in developed and developing world
Low Technology Risk - EcoPark

Waste Pickers
• Very time and resource efficient at removing recyclable materials from waste dumps• Children and women also form a large section of this group of informal entrepreneurs• According to information released by them, recycling provides productive work for an
estimated 1% of the population in developing countries• Recycling provides 10 times as many jobs per tonne of waste as do incinerators and
landfills• Reducing child labor, improving education, and providing access to health care,
education, food, water and housing though W2WF
VM Press
http://www.vmpresstechnologies.com/
• Municipal waste is unloaded in the reception area and directly fed into the hopper of extruder press - grab bucket
• Extruder size from 10-30 T/hr; batch process• The extruder press separates the input waste into two fractions: a dry and a wet fraction• The dry fraction, which has 20-25% moisture and a calorific value equal of about 13,000
kJ/kg (and density of 0.6-0.8 T/m3) is accumulated into wheeled collection bins and directly sent to gasification
• The wet fraction, which has 60% moisture (Total Solid TS=40%) is conveyed by way of an Archimedean screw system to the anaerobic digestion plant
• The anaerobic digestion occurs in a high-solids dry anaerobic digestions process

WetDry
Harvest Power
Efficient, simple, low cost• Higher annual processing capacity,
shorter retention times and increased loading rate
• Limited preprocessing requirements -no grinding, slurring or filtering
• Simple loading process (front-end loader) - no complicated continuous feed system
• Lower parasitic energy consumption• Modular, scalable and flexible (siting,
feedstocks and waste size)
Sophisticated process control• 15‐20% higher methane content than
comparable single stage systems• Increased plant stability due to optimization
of environmental process conditions in controlled, separate steps
• Flexibility to process a wider variety of wastes than other comparable systems due to the fact that methanogens are not exposed to acidic conditions during hydrolysis ensuring greater reliability

Concord Blue
• Patented technology (steam thermolysis) converts most waste into renewable energy• Unique method relies on heat transfer instead of incineration—efficiently producing a
highest quality syngas without needing a flame• Closed-loop system sustained by the byproducts it creates, producing its own energy so
that no additional fuel is needed once the process begins• Waste inputs are heated in an oxygen-starved environment – no oxidized pollutants
produced (dioxins and furans)• With no need for costly add-on scrubbers to clean emissions, the process is not only
better for the environment, but also more cost-effective
• Flexibility - feedstock, end product and scale
• Outputs include syngas (convertable to electricity), biochar, clean water, ash, heat for conversion of energy, heat for producing hot water and heat for cooling
http://www.concordblueenergy.com/
Concord Blue
http://www.concordblueenergy.com/
• The Concord Blue Reformer is different
from incineration because waste isn‟t
burned
• The process is entirely devoid of
oxygen where the waste is thermally
decomposed into syngas
• Waste is converted to syngas by
heating it at a very high temperature in
the absence of air
The process
• Staged reforming: three spatially
separated vessels
• Fully automated
• Waste material is segregated and dried
• Waste material is fed into a thermolysis
system to gasify input to 95% gas and
5% char
Baleen International
• The Baleen Filter offers several important industry advantages when compared with many conventional screening and filtration systems
• Patented combination of clearing fluid dynamics and mechanical principles to instantly separate fine suspended solids from all types of water based streams
• Fully automated with simple controls• Uniquely self-cleaning, works with flocculation• Flexible format - multiple install design formats and product available
• Dramatically reduce energy, mainte-ance and chemical consumption for direct cost-savings and betterment of the environment
• Cost effective (vs competition) -reduction in: CAPEX of 25-75% & OPEX of 25-95%

no methane, no disease
• Clean energy produced and recyclable
materials recovered
• Highly attractive net
returns to investors
• $6M+ EBITDA/EcoPark
• Direct employment at an
EcoPark for Waste Pickers

housing, income for the
bottom of the pyramid
(waste pickers)
Summary
• Unique combination of proven
in-market technologies
• Triple bottom line impact
