The coking process yields a number of by-products that are important input materials in the chemical industry.

The digestion process begins with bacterial hydrolysis of the input materials.

Another key consideration is the carbon:nitrogen ratio of the input material.

Digestate is the solid remnants of the original input material to the digesters that the microbes cannot use.

A compression scheme in which each unit of input material can be compressed to different sizes.

As a result, the input material is transformed into the desired output product.

New buildings can also be constructed using less carbon-intensive input materials.

Anthracite produced by the company is used mostly an input material for the steel-making process.

Depending on composition and impurity level of input material, the general following process steps are applied.

It used hemp as its main input material.
