2. THIS PRACTICE IS EMPLOYED ALL OVER THE WORLD.
THE ENERGY IS RENEWABLE, CARBON FREE AND
SUSTAINABLE.
SUCH A PLANT REQUIRES A MUCH SMALLER AREA THAN
SOLAR PANELS OR WIND GENERATORS AND PROVIDES HEAT
AND ELECTRICAL ENERGY WHICH THE FORMER DON’T.

3. MUNICIPAL SOLID WASTE IS BIOMASS
THAT CAN BE GASIFIED TO GENERATE
HEAT AND POWER.
THE WASTE CREATED BY A MILLION
PEOPLE CAN PROVIDE ENOUGH
ELECTRICAL ENERGY TO SUPPLY 50 000
HOUSEHOLDS.

5. LAND FILLING RECYCLING

6. INCINERATION CONVERTING

8. ONE TONNE OF MSW
PRODUCES 2170 kWh OF
ELECTRICAL ENERGY WHICH IS
SUFFICIENT TO SUPPLY TWO
LARGE HOUSEHOLDS WITH
POWER FOR A MONTH

9. China 128,6 kg pp/year = 0,3523 kg pp/day
London in Ontario = 2,1 kg per person per day
(pppd)
Kumasi in Ghana = 0,62 kg pppd
United Kingdom = 1,6 kg pppd
USA = 1,65 kg pppd
South Africa? Probably similar to UK but the
value for China is used in this feasibility study
as a worst case scenario.

10. Total MSW generated by 900 000 citizens
= 630 ton/day at 0.7 kg/person/day
Heat energy from 630 ton of MSW
= 1 490 000 kWh/day
Average heat power produced is then
1 490 000/24/1000 = 62.1 MWheat
Electric power with 30% efficiency
= 20,5 MWelec

11.  Heating and air–conditioning of
buildings
 Refrigeration and ice making.
 Making ammonia or urea to
produce fertilizer.

12. ENVIRONMENTAL IMPACT ASSESSMENT TO BE DONE JOINTLY BETWEEN
CONTRACTOR AND CLIENT
APPROVAL BY THE NATIONAL ELECTRICITY BOARD TO SELL POWER TO YOU
MUTUAL CONTRACT TO PURCHASE A CONSTANT AND FIXED AMOUNT OF ENERGY
FROM US IRRESPECTIVE OF SEASONAL OR TIME OF USE REQUIREMENTS.
WE UNDERTAKE TO DELIVER TO YOU A CONSTANT AMOUNT OF ENERGY FOR
EACH HOUR OF THE YEAR. MAINTENANCE SHUT DOWNS WILL BE MINIMAL AND
MUTUALLY ACCEPTABLE.
BREECH OF CONTRACT CLAUSES MUST BE MUTUALLY ACCEPTABLE.
WE NEED A SERVITUDE FOR A SITE AND ACCESS ROADS.
