What’s a digester?
Digester is a device that does the processing or “digest” of organic material. This process is known as “anaerobic digestion” (without air or oxygen) micro organisms that decompose organic matter. The result is energy generated from gas or biogas. This “biogas” is composed of a mixture of gases, mainly methane and can replace oil or natural gas that must be extracted from underground. It is a kind of recycled and recyclable resource that produces a closed loop.
We can use biogas for cooking and use the leftovers to produce more biogas. In Peru, a project is taking advantage of cattle dung to produce cooking gas and organic fertilizer. In California, a company uses the remains of its production of onions to produce electricity for its plant onions. It is not expensive to build a digester or even purchase a digester for household use.
Some people use a digester with worms to turn food scraps of everyday life into fertilizer for my plants. Besides contributing to the reduction of waste that pollutes the environment, they save money to buy fertilizer for their plants!
