RACEMAT: GREEN ELECTRICITY GENERATION FROM WASTES
PROBLEM STATEMENT
Depletion of natural resources
High cost of activated sludge treatment and
limited space for landfills
Volume of solid and liquid wastes in wastewater
treatment plants ↑
Global warming ↑ Price of fossil
fuel ↑
W e l e a d
FROM WASTEWATER TREATMENT PLANT WASTES
TO RENEWABLE ENERGY SOURCES
RACEMAT, AN ALTERNATIVE SOLUTION
W e l e a dRACEMAT : what is it?
RACEMAT is a device that use bacteria as the catalyst to oxidize organic and inorganic matters in biosolids. Electrons produced by bacteria from this biosolids are transferred to the anode and flow to the cathode linked by a conductive material containing a resistor. The anodes of this RACEMAT behave as bacteria’s typical electron acceptor and thus, the movement of the electrons to the cathode of this device through a resistor, generates electricity.

RACEMAT: GREEN ELECTRICITY GENERATION FROM WASTES
COMMERCIALIZATION POTENTIAL
Can be scalable to produce electricity at higher power/voltage
Simple and economical process Alternative renewable energy simultaneously
with wastewater treatment Great contribution to solve high cost for disposal
of biosolids/activated sludge Single chamber of microbial fuel cell can achieve
up to (0.3-0.7 V)

COMPARISON BETWEEN CONVENTIONAL ELECTRICITY GENERATION AND RACEMAT
TECHNICAL DESCRIPTION CONVENTIONAL ELECTRICITY GENERATION RACEMAT
RAW MATERIAL Fossil fuel such as natural gas and diesel
Biosolid wastes from the wastewater treatment plant
AVAILABILITY OF RAW MATERIAL Fossil fuel resources around the world will be depleted soon
Biosolids was generated continuously from the residence and industry which is plenty and keep on increasing and free of charge
IMPACT TO ENVIRONMENTWould create greenhouse gas effect which will cause great global warming due to pollution
Solve environmental pollution by utilizing the biosolids/wastewater from the treatment plants
COST The cost of fossil fuel keep increasing over year
The cost is basically free due to activated sludge is an unwanted waste

RACEMAT: GREEN ELECTRICITY GENERATION FROM WASTES
CHARACTERISITICS PRESENT PRODUCT (RACEMAT electricity generation from wastes)
COMMERCIAL PRODUCT / PROCESS (Example: Hydroelectric power)
Raw material Waste – Activated sludge Water
Abundance of raw material Plenty – Produce throughout the year from wastewater treatment plants
Depend on rainfall throughout the year
Cost of construction Cheap and relatively simple to construct
Very expensive due to large land area needed, and the materials for contruction of dam. Maintenance cost is very high
Impact to environment No negative impact to environment Construction of dam would destroy the environment due flooding to the surrounding area – destroy the “Orang Asli “ habitat
Problem to society Solve the problem for disposal of sludge and cleaner
Can create waster access problems to surrounding residence
COMPETITOR ANALYSIS
W e l e a d
RACEMAT: GREEN ELECTRICITY GENERATION FROM WASTES
IMPACT OF RACEMAT TOWARDS → →:
INDUSTRY: alternative renewable energy for electricity and wastewater treatment, opportunity for industries to generate their own electricity supply
ECONOMIC: alternative cheap renewable energy from wastes instead of non-renewable energy
SOCIETY: a cheaper renewable energy which is green and clean. By recycling biosolids/activated sludge, pollution due to its disposal can be reduced and provide free-pollution to the environment.
SUSTAINABLE DEVELOPMENT: reduce utilization of non-renewable resource (gas/fossil fuels) for electricity and reduce pollution potential
recycling of wastes + generation of electricity → sustainable development
