3. 2 “Profit from Waste”
Project Outline
Managing waste and sanita-
tion de-centrally in “PPP”
platform, is conceived as new
way of creating employment
whereby Public Private Part-
nerships will help the Local
Authorities to cope with the
challenge of service provision.
It is a GIZ (Germany Embas-
sy) funded pilot project in
Mzuzu at Luwinga Area 1B.
Market, in collaboration with
Mzuzu City Council, Mzuzu
University, and design by
“Profit from Waste” is an initiative aimed at help- 4th Architectural Dimension.
ing local communities manage their waste while
generating income from the same.
Project Facility
Restaurant, Public pay toilets and showers is located next to a produce market
which operate by use of Bio-Energy “Methane Gas”. The facility is centred on the
operation of a biogas digester. The site may be used for additional communal us-
es, such as child care and communal gatherings.
Organic waste from the market, from households, and from the pay toilets is di-
gested in the biogas reactor.
Bio-gas produced from the system would be used as a source of energy for cook-
ing (separate restaurant business at same location) and/or heating (water of pub-
lic showers).
Grey water from showers is treated separate through small reed bed, and efflu-
ent may be used for irrigation.
Facility should have solar hot water heating if biogas is not used for heating.
Simple solar photovoltaic for lighting (without need of inverter) with use of Ener-
gy Server Bulbs.

Project Outline
SYSTEM OPERATION OUTLINE
Project Facility
 Covered waste segregation site, where non-biodegradable materials are separated
for recycling.
 Waste delivered from households to site, through incentive program i.e., for pay-
ment of money or token for the use for public facilities.
Project Construction Theme
The project is using sustainable construction material through the use of com-
pressed earth blocks. ( Soil Stabilised Blocks)
 Rain water harvesting for the use in vegetable garden and toilet flushing, which,
however needs support from piped water as backup in dry season.
 Facility should have renewable energy sources; solar power lighting and water heat-
ing and biogas for cooking.
