The GREEN Circular Process

Circular’s Green Processing Philosophy

Circular strictly uses the elements of the earth and the science it has developed to recycle waste to nutrients and energy. The biomass, also called vegetation or plant residues, with which we work as a company, contains only “residual products” of organic matter. This means that Circular only processes organic material which can no longer be used for human or animal nutrition.

Science tells us that the sun causes the growth of carbon particles (chemical element “C”) in our vegetation and the growth of organic matter:

• The sun is our only source of energy on earth.
• A plant is made up of a combination of organic matter and water. The organic material (or humus) is in turn made up of carbon compounds and minerals.
• The basic elements a plant needs to live and grow are sunlight, CO2 and water, the three elements that play a leading role in photosynthesis. In addition, the plant also uses all kinds of minerals that should be present in the soil and nitrogen from the air.

At the Circular plants, our process calls for biological treatment at our biomass plant in a fermentation process, an accelerated natural phenomenon, in which anaerobic bacteria eat and convert the organic matter (excretion) into methane gas (chemical element “CH4”) and carbon dioxide gas (chemical element “CO2”).

• The carbon dioxide is used gaseously via the air as a basic growth element for the vegetation. (Circular)
• The methane gas is burned in a CHP combustion plant, converting the carbon element (C) from CH4 into green electricity and green heat.
• The water particles (-H4) evaporate in the air and are used again in the form of rain as a basic growth element for the vegetation. (Circular)
