Activated carbon from leaves (CoAct)

Researchers in the Friedrichshafen region wish to convert leaves and other residual biomass into activated carbon and fuel in the “CoAct” project. TZW is investigating the activated carbons in terms of their performance to remove micropollutants.

Leaves or landscaping material such as grass cuttings from nature conservation areas do not necessarily need to be composted. Researchers in the CoAct project are developing a technical method to produce activated carbon and energy from this kind of material, referred to as residual biomass.

The scientists are working on a concept to implement this principle in Friedrichshafen, Baden-Württemberg and the surrounding Lake Constance region. Local farmers are providing prunings from fruit trees, for example, for energy and activated carbon production. The acquired products should help the regional economy, protect the climate and improve water quality, thereby helping the sustainable development of the communities in the town and district.

The produced activated carbon from various starting materials is investigated on a laboratory scale and semi-technical scale at a waste water treatment plant, to establish the adsorption capacities with regard to micropollutants and to compare it with commercially available products.
