Although there are controversies regarding landfill with organic waste. But it can be used for land reclamation along with improving environmental conditions. Most researchers believe and even it is a proved fact that organic wastes have a great potential to generate electricity or gas. But the initial production cost will be higher.

Most researchers believe and even it is a proved fact that organic wastes have a great potential to generate electricity or gas. But the initial production cost will be higher. 

Most of cases, for organic waste management prominent usages are composting and vermicomposting. And also bio gas production is also utilized to reduce methane pollution, however ultimate byproduct is carbon dioxide. This bio gas can be used for electricity generation.   

Alternatives are:

- fermentation in airtight tanks and obtaining biogas

- or drying of solid waste on special beds, and obtaining energy by incineration

Thank you all for your valuable comments, Kamrul Islam , Disna Eheliyagoda ,Barbara Sawicka ,  Iuliana Florentina Gheorghe, the composting is something good for improving soil and increasing the productivity of crops, but we must be careful not to add pollution to the environment.
