Recycling and Waste to Energy

After passing through the Waste Cleaner, garbage is reduced to less than a 20% of its initial volume, and it leaves the process in a format that makes very easy the selection of materials, so that we obtain the following products

BIOMASS

We call it MOTBE (Bio Thermo-Stabilized Organic Matter). Into this fraction integrates all organic matter, and also paper and cardboard that comes mixed in the "black bag" household waste. Everything takes a homogenous format, free of pathogens, and capable of being used in multiple processes for energy production, such as:

  • Biogas obtention by anaerobic digestion.
  • Syngas obtained by the gasification process.
  • Getting biofuels.
  • Production of ethanol and methanol.
  • Production of power by combustion.

METALS

The metals leave the process very clean, no labels, no painting, thus increasing its value by saving recycling costs. Then they are classified in ferrous, aluminum, and other nonferrous metals. Aluminum also could be processed to obtain hydrogen.

PLASTIC

The PET remains its form. The rest of plastics takes a format of solid balls, with high calorific value, and could be used to generate power, and also to obtain fuels. In the Waste Cleaner, for example, the trash bags are reduced to a little ball, leaving aside the typical problems that arise when caught in conveyor belts in conventional plants.

INERT MATERIALS

It is a fraction between 10% and 20% of MSW. It includes inert materials such as debris, pieces of glass, textile or rubber. Initially this fraction is not recoverable at the end of the process. But actually both the fabric and the rubber can be recycled or even used at energy purposes. The rest of inert materials can be used as filler in public works.
