The document discusses a sustainable economic solution to manage municipal solid waste (MSW) and wastewater through the Clark-CWTI-Evergreen Integrated Waste-to-Energy Conversion System (IWECS). This system converts waste into valuable by-products such as biogas, organic fertilizer, clean water, and electricity, significantly reducing pollution and the need for traditional landfills and wastewater treatment plants. IWECS is scalable, cost-effective, and promotes environmental stewardship by transforming waste from a liability into an asset.

1. Creating a Sustainable Economic Engine
WASTE-TO-ENERGY

2. THE PROBLEM
Large and growing volumes of municipal solid waste (MSW), sewage, and wastewater
are produced in communities every day, filling landfills and wastewater treatment plants
(WWTPs). As time passes and populations increase, these large, traditional, chemically toxic
landfills and WWTPs, whose design and construction has not changed significantly over the
past 80 years, are exceeding capacity and significantly polluting our environment. A paradigm
shift in the process for the next 100 years has emerged through utilization of new and existing
technologies.
THE RECOMMENDATION
A better way to treat solid waste and wastewater is via robust technologies such as the Clark-
CWTI-Evergreen Integrated Waste-to-Energy Conversion System (IWECS). IWECS provides an
efficient means of reducing the volume of municipal solid wastes (MSW) and sewage. The
wastes are converted into valuable products and by-products such as biogas or green electric
power, organic fertilizer, and clean water.
By following IWECS process conversion, waste storage issues and associated air and water
pollution are significantly reduced. In addition, the significant capital and operating costs
associated with the construction and operation of traditional landfills and wastewater
treatment plants are significantly reduced.

3. THE SOLUTION
The Integrated Waste-to-Energy Conversion System is the gift that keeps on giving,
thanks to the valuable by-products it produces:
Biogas and electricity. Converting most of an organic waste stream into
methane-rich biogas is completed through a patented and robust process, which
happens to be the most efficient biocatalytic process available in the world today.
Fertilizer. The NPK-specific organic fertilizer by-product of IWECS is of a higher
quality than any of today’s fertilizers; it is renewable and highly bioavailable,
unlike commercial fertilizers, yet is almost odorless and high in nutrient content,
unlike most organic fertilizer products.
Diesel Fuel. Many of the plastics and tires that are sorted from the MSW can be
converted back into a valuable No. 2 diesel fuel. This fuel, which is not biodiesel,
can be used to run most diesel engines.
Clean Water. In addition to converting food and agricultural wastes, MSW, and
sewage into valuable “green” energy products, organic fertilizer, and recovering
clean water, the IWECS also mitigates pollution caused by the gaseous emissions
and liquid leakage from landfills and other MSW containment sites. Each plant’s
streamlined design mimics the efficient and patented anaerobic biocatalytic
digestion process that makes IWECS work.

The infrastructure for power generation requires the gas engine and other system components to convert gas into
electricity. It is assumed that the electricity will be transmitted into an existing transmission grid. The capital cost of
power transmission is not included. The land area needed for each facility depends on the amount of waste treated
and MW of power generated. In addition, since the system is modular, additional land may be acquired for future
expansion. The land requirements will be disclosed in the financial/commercial proposal.

THE BENEFITS
Green.
Rather than simply adding to an already large pile of trash in a landfill or pumping chemicals to
remove dangerous water contaminants, IWECS creates an economically viable fertilizer by-product
and clean water without chemical treatment.
Single Process.
IWECS significantly reduces the need for landfills and wastewater treatment facilities, instead
combining them into one all-encompassing system.
Scalable.
No space to install a full-scale water or sewage treatment plant? No problem. Since each IWECS
system is custom designed, it can be scaled to meet the capacity needs of each user.
Self-Sustaining.
The energy produced by IWECS can be used to provide gas or electricity to a business and/or a
community. The excess may be sold back to the existing utilities that provide gas and electrical
service to the community, thereby completing the full circle of the sustainable treatment cycle.
Cost Effective.
Because IWECS can process virtually any organic source material and does not require the addition
of costly treatment steps and chemicals, the only cost associated with it after installation is
maintaining and powering the system itself (the cost of which can be offset by selling or reusing the
energy, water, or fertilizer produced).
