The COMBINE Project


Developing waste-based energy

The challenge

The effective use and development of environmentally-friendly technologies are key to increasing the availability of renewable energies. The use of biomass (green cuttings, waste water, and liquid leftovers) as an energy resource has a unique and important role in the renewable energy field. Unlike wind and photovoltaic renewable energies, biomass can be stored over a long period of time, and community sewage treatment centres can be placed strategically without competing for fertile land that may be needed by other industries.

Therefore, most countries and regions in North-West Europe are facing an increasing demand of energy from biomass and bio-fuels

The project in brief

The COMBINE project contributed to this rapidly advancing field by using an innovative technology developed at the University of Kassel called IFBB. This technology aimed to develop an environmentally-friendly biofuel production by using green cuttings and waste water to create clean water, compost, fuel, electricity, and heat.

By focusing on utilising abandoned urban, natural and agricultural areas for the production of energy, COMBINE maximized its resources and advanced the field of renewable, storable energy.

 

COMBINE created new energy supply chains from biomasses in the project regions and beyond.

The impact

COMBINE explored and exploited new sources of bio-energy from waste materials based on roadside green-cuts, grassland and other organic waste materials. They created new energy supply chains from biomasses in the project regions and beyond, which triggered large-scale investments in decentralized bioenergy production.

Additionally, the research introduced IFBB technology to existing biogas and waste water treatment plants, optimising their processes and utilizing previously wasted thermal energy. Biomass was harvested at all partner sites, silaged and sent to the large-scale sedentary IFBB plant in Baden-Baden for test processing (shown in video). 

This pilot also contributed to reducing the conflict between bio-energy and food production by exploring the utilisation of new raw materials, illustrating that it is no longer necessary to compete with the food industry for the use of fertile land. 

Most importantly, COMBINE used major strategic innovations, contributed to the development of an environmentally-friendly biofuel production, supported nature conservation, and reduced the emission of large amounts of methane.
