ADVANTAGES OF BIOGAS
- Renewable energy source
- Raw materials use in production are renewable
- Requires low capital investment
- Technology used is pretty cheap. Biogas can be developed at home used for cooking and generation of electricity
- Minimizes overreliance of fossil fuels
- Helped cut back on fossil fuels use eg: oil, gas and coal
- Produces enriched organic manure
- The process biogas generation leaves behind enriched organic manure ; perfect supplement / replacement of chemical fertilizer
- Reduces amount of waste going to landfills
- Organic materials can be used to produce biogas
ADVANTAGES OF COMPOSTING
-
- Add nutrients to the soil
- Humus-nutrient-rich soil. Add nutrient ; carbon & nitrogen.
- Helps retain water for plant used
- Recycles kitchen & yard waste
- Keep 30% waste
- Wont be a need to buuy trash bags / take out the trash
- Good environment
- Free & healthier
- Not rely on factory-made fertilizer & chemicals
