BENEFITS
Advantages of biogas digesters
•Produces clean source of energy, methane gas that can be used
for cooking purposes, lighting, water heating and to generate
electricity
•Digests organic waste (from the kitchen, garden, sewerage,
animal manure, etc.)
•Produces organic compost as waste product (in liquid, slurry or
solid form), this can be used to grow vegetables.

BENEFITS
Advantages of biomass gasifiers
•Produces clean source of energy, producer gas that can be used
for heating and to generate electricity.
•Uses readily available renewable energy resources.
•Can be used for establishment of community based projects such
as the one at Melani village.

TYPICAL COSTS AND RISKS
•Biomass gasifiers costs about R15-20 000 per kVA installed.
•Biogas digesters cost about R5000 per m3 installed.
•The risks depend on individual projects and the business model
employed.
•Limited to areas/households with biomass resources.
