Waste & Energy Issues in the Philippines
SOCIO-ECONOMIC SETTING
RAPIDLY EXPANDING PHILIPPINES’ ECONOMY projected growth of at least 6% in
2013; Fitch’s investment rating of BBB.
STRONG ECONOMIC EXPANSION creates large demographic shifts from rural
areas to large, rapidly growing urban communities.
FAST GROWING URBAN COMMUNITIES face major challenges:
• Increased municipal solid waste (MSW) and unsustainable landfill space;
• Inadequate MSW management equipment and infrastructure;
• Unsustainable MSW management practices & illegal dumping causing floods;
• Increased pollution with contamination of land and water resources;
• Increased CO2 emissions;
• Increased health concerns caused by pollution and contamination; and
• Energy security needs Renewable Energy resources.
SOLUTIONS FOR (i) MSW management and (ii) electricity supply are urgently
sought by National and local governments in the Philippines.

EnvirOcycler© Technology provides Long-term, Integrated Multi-Purpose Solutions with
Attractive Sustainable Returns
Versatile two-stage gasification and thermal oxidation processes create
producer gas from dry and wet biomass from MSW for generating
electricity.
Thermal oxidation products at 1,010°C can be used to produce steam for a
condensing steam turbine or, alternatively, for an organic Rankine cycle
turbine generator.
Net power generated by a single 105 GJ/h EnvirOcycler unit is
approximately 5.5 MWe.
Parasitic load is minimal making it very efficient in generating electricity,
while other gasification technologies require high power inputs.
Biomass moisture content between 35% and 60%, therefore no external
energy required to pre-dry feedstock.

The EnvirOcycler provides two, long-term, integrated solutions for problems
arising from rapid urban growth while generating investment benefits
The EnvirOcycler© Solution
Two-stage gasifier-thermal oxidizing (GTO) technology converts dry and
wet organic fraction of municipal solid waste (MSW) into thermally
oxidizable gases and heat for clean electrical power generation.
Gasifies dry and wet biomass in its large first stage; Oxidizes the first
stage "producer gas" in a second stage; Heat production for electricity
generation and/or industrial processes.
Two immediate solutions:
• Complete sustainable waste management solution, reducing and/or
eliminating alternative disposal methods for MSW such as landfills;
• Electricity production to meet energy security.
Flexibly configured for large and small towns and cities, and for other
industries and sectors.
Ideal for Public-Private Partnerships turn-key investment projects such as
a build, own, operate and transfer (BOOT) scheme.

Single EnvirOcycler offsets equivalent of
US$10 million in imported fossil fuels (at
$100/barrel) per month
MSW fuel loads, as follows:
• 287 tonnes/day of MSW at 35% moisture content; or
• 358 tonnes/day of MSW at 45% moisture content; or
• 476 tonnes/day of MSW at 55% moisture content.
Minimum 35% moisture content means energy from
the process does not need to be parasitized for
drying the waste prior to processing, unlike other
gasification technologies, produces more energy for
generating electricity resulting in a higher output
efficiency and higher revenues.
With an average of 1.5 kg of MSW per capita/day, an
EnvirOcycler unit converts the organic fraction of
MSW into electricity for communities with
populations between 184,000 to 305,000.

Minimal EnvirOcycler Emissions
Emissions from the 2-Stage EnvirOcycler are minimal due to the vigorous,
cyclonic, double vortex, thermal oxidation process employed in the
EnvirOcycler’s 2nd stage. The EnvirOcycler’s 1st stage is a very large, gentle,
updraft gasifier.
EnvirOcycler emissions are significantly less those set by the US
Environmental Protection Agency for all emissions. This includes:
• less than 1 ppm for CO;
• less than 15 ppm for NOx;
• less than 100 mg/m3 for particulate matter;
• No traceable toxins; and
• Further reductions to these emissions if:
• a selective catalytic reactor is added to eliminate the NOx by
converting it to N2 and O2; and
• a “bag house” is added to capture particulate matter.

Benefits: Project registered under the
United Nation’s Clean Development Mechanism
(CDM) can generate Carbon Credits for added
revenue for offsetting CO2 and methane
7
• Increases energy security from renewable energy, generating revenue by selling
electricity to the National Grid Corporation of the Philippines (NGCP) and
Distribution Utility or Electric Cooperative;
• Offsets expensive imported fossil fuels, Reduces production of greenhouse gases;
• Marketable by-products, e.g., soil conditioners, concrete additives, etc.;
• Revenues from the recovery of recyclable materials from the upstream MSW;
• Eliminates need for expanding/new landfill sites/improved productive land use:
• Reduces soil and ground- and surface water contamination;
• Mitigates environmental pollution to rivers, land and air (Green House Gas -
methane);
• Lessens health concerns of landfills and open MSW disposal/incineration;
• Reduces pest infestations and improves community aesthetics near landfill
sites.
• Creates employment (minimum 80 persons per 105 GJ EnvirOcycler unit).
Benefits to the Project Investor
An EnvirOcycler project quickly generates benefits to investors
using the proposed Puerto Princesa project model and preliminary
analyses:
• Establish one 105 GJ/hr EnvirOcycler using 450 tons MSW/day at 50% MC;
• Estimated capital cost of $43.6 million per EnvirOcycler unit;
• Waste tipping fee of $15/ton (typical in the Philippines); and
• Electricity feed-in rate of $0.18/kWh*.
RETURNS ON INVESTMENT
• Return on investment of 17%. (EOCC in the Philippines is about 10%);
• Payback period can be as short as 5.5 to 6 years.
*Used the $0.18/kWh tariff rate for metro Manila. In the provinces the rate is much higher and can reach as high as $0.80/kWh.

The EnvirOcycler in Malaysia
A third 105 GJ/hr EnvirOcycler project is
currently being implemented in Malaysia
to provide industrial process heat using
MSW from Kuala Lumpur.
First Stage gasifier
Second Stage thermal oxidizer
12
Two 105 GJ/hr EnvirOcyler units
dedicated to the use of palm oil
industry waste generate 11 MWe
provided to the Malaysian
electricity grid.
Puerto Princesa EnvirOcycler Project
The facility will be developed near the existing sanitary landfill, 26 km north
of Puerto Princesa, Philippines. The advantage of the location is to mine
and use the MSW in the landfill as feedstock in addition to the incoming
stream of MSW collected daily.
The project will consist of one or more 105 GJ/hr EnvirOcycler units with a
capacity to convert 450 tonnes of MSW per day at 50% moisture content.
One unit will generate up to 5.5 MW of firm supply of grid electricity using a
steam turbine or an Organic Rankin Cycle (ORC) turbine.
Estimate installation time of a 105 GJ/hr EnvirOcycler and electrical power
generating station is 18 to 24 months from time all legal and regulatory
permits have been received. The final estimated cost of installing an
EnvirOcycler depends on many factors to be ascertained during the
Feasibility Study after a final agreement to advance an EnvirOcycler project
has been reached.
13
Costing and Financing of the Project
The cost of the facility is preliminarily estimated at US$44 million per EnvirOcycler
Unit.
Investment will be paid back through revenues from municipal tipping fees assumed to
be $15 per ton, and the sale of renewable energy to the grid of at least $0.18/kWh (Manila
rate), although in Palawan it can be as high as $0.80/kWh.
Major electricity sales can be arranged through the Ancillary Services Purchase
Agreement (ASPA) for Peaking load, Regulating Reserve, or Load-following to the
National Grid Corporation of the Philippines (NGCP) and or a Bilateral Power Supply
Agreement with the Electric Cooperative or Distribution Utility.
Operating cost of the EnvirOcycler are estimated at $7 to $8 per ton of MSW.
Added revenues from separated recyclable materials and sale of bottom and fly ash as a
concrete strengthening and durability enhancement additive, an agricultural soil
conditioner or liming agent.
CDM revenue stream for a period of 10 years. Therefore, CDM revenues could increase
the rate of return on the project, and substantially reduce financing risks.
