Zero waste to landfill

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

Zero waste to landfill

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

• Currently practiced commercially around the world

• Use waste picker community coupled with some automation of machinery

Separation

• Use VM Press technology – high pressure (~1000 bar) to increase organic content

• 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

• All vendors are in commercial-scale facilities around the globe• There are no new, untested, technologies being incorporated into an EcoPark • Vendors are selected as ‘best in class’ for the approach (and shown as examples)• The output of one process is matched to the input of the next process

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

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


• 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%
