Envireco is participating in the LIFE+ project MARSS, Project LIFE+ ENV/DE/343
Project acronym: MARSS
Project title: Material Advanced Recovery Sustainable Systems,  
Project duration: 09/2012–12/2015
Project budget: € 4,154,933
EU contribution: € 2,073,727

RegEnt GmbH is co-developing an innovative process (known as MARSS) for the production of organic fuels derived from mixed waste (Municipal Solid Waste) with 4 other European partners. This EU Life plus co-funded project is taking place on the premises of Entsorgungs- und Verwertungszentrums (EVZ) in Mertesdorf, Germany. Additional project partners are RWTH University of Aachen (acting as coordinator), pbo GmbH, as well as the Universitá degli Studi di Napoli and the Universitat Autónoma de Barcelona.

The plant has a throughput of about 10 t/h and will demonstrate the separation of biogenic fractions found in the MSW (up to 50 %) as well as testing the use of the produced CO2 neutral biomass fuel as a feedstock for renewable energy production in decentralized combined heat and power units. We expect 30-40% mass recovered RRBF output from produced over an operation tie of 200 days in the project running time giving 2000 t/a. Amounts of metal recovered: tests sampling indicated a recovery rate of about 200kg/h. Ferrous metals should be 140kg/h. NF metals recovery should be 60 kg/hr. Batteries recovered are estimated to be about 5% of the recovered ferrous metal scrap fraction.

The MARSS project has identified various direct and indirect potential environmental benefits:

  • Reduction of harmful GHG emissions
  • Reducing biological municipal waste going to landfill
  • Reducing landfilling of valuable metals and other materials suitable for recycling
  • Local production of electricity and heat from household waste as well as increasing renewable energy potential for urban communities.
  • Prevention of soil and ground water contamination from landfill sites all over Europe

Project location: EVZ Mertesdorf, Rheinland-Pfalz


  • Sorting a RRBF from dry MSW with standardized and proved waste technology
  • Design a RRBF quality that is suitable for power plants using fluidized bed technology
  • Achieving a high yield of RRBF complying with biomass fuel standards Improving the economic efficiency of MSW treatment referring to EU landfill-directive
  • Improving the ecological performance of MSW treatment considering high social acceptance
  • Assessment of social impacts

Life Cycle Analyses as well as an assessment of socio-economic impacts of this process enables a broad evaluation of this innovative technology.

Country specific studies for Italy, Spain, UK, Greece and the Czech Republic will be carried out and will deliver additional information about the acceptance of this innovative process as well as the potential markets for biomass renewable fuels from waste in these countries.

A detailed investigation focused on Naples and the surrounding area will be carried out to determine a realistic commercial application of the MARSS technology.

Added Value

  • RRBF separated from MSW reduces the total mass of landfilled waste minimising landfill capacity demand and landfill emissions
  • RRBF as CO2 neutral fuel is highly valued in competition with fossil fuels
  • The option to produce RRBF by adding modular technologies to existing or mandatory MSW treatment plants offers economically attractive opportunities


  • Challenge 1: process efficiency of biological drying is the main driver to achieve sufficient results
  • Challenge 2: a large number of samples representing the whole scope of feedstock qualities is necessary to achieve reliable results
  • Challenge 3: feasible adjustment of the RRBF process based on large-scale burning tests
  • Opportunity 1: RRBF production suitable for fluidised bed combustion
  • Opportunity 2: RRBF designed for utilisation as additives e.g. in sewage sludge treatment
  • Opportunity 3: RRBF with an enrichment of Phosphorus in residual ashes

Expected results

  • Reducing biological municipal waste (BMW) going to landfill by providing a recycling system that can catch the lost fractions
  • Reducing incineration of NF metals and increase of recycling of NF metals
  • Energy savings through the use of secondary (recycled) metals
  • Aim of project is also to provide an alternative to Mixed MSW incineration using instead energy recovery from biomass
  • To assist local communities to find a viable alternative to landfill (legal or illegal)
  • Reduction of harmfull emissions
  • Production of high value fuel that can serve the community
  • Production of green fuel
