Helindustöös

Helindustöös is a term that describes the process of transforming waste materials, particularly plastics and organic matter, into valuable industrial feedstock or energy. This method aims to divert waste from landfills and incineration, promoting a more circular economy. The core principle involves breaking down complex waste structures into simpler chemical components that can then be reused in various manufacturing processes or combusted to generate heat and power.

The specific techniques employed in helindustöös vary widely depending on the type of waste material being processed. For plastics, common methods include pyrolysis and gasification, which use high temperatures in the absence or limited presence of oxygen to break down polymers. Pyrolysis yields oils, gases, and char, while gasification produces syngas, a mixture primarily of hydrogen and carbon monoxide. Organic waste, such as food scraps and agricultural residue, can be treated through anaerobic digestion, where microorganisms break down organic matter in the absence of oxygen, producing biogas (rich in methane and carbon dioxide) and digestate, a nutrient-rich slurry.

The products derived from helindustöös can serve multiple purposes. The oils and gases from plastic pyrolysis can be refined into fuels or used as raw materials for new plastics. Syngas from gasification can be used to generate electricity or synthesized into liquid fuels and chemicals. Biogas from organic waste can be burned for heat and electricity, or upgraded to biomethane for injection into the natural gas grid or use as a vehicle fuel. Helindustöös offers a potential solution for managing challenging waste streams and reducing reliance on fossil fuels.
