Garbage as a source of energy
Garbage or municipal solid waste can be a source of energy by burning it in special power plants or by capturing the gases it releases. When trash is burned at special waste power plants, it produces steam that can be used either to heat buildings or to generate electricity.

We can also obtain energy from garbage by letting it rot in landfills. When biodegradable garbage rots, it releases methane gas also called biogas that can be collected and used as a fuel source.
