Performance of European biogas plants towards methane emissions
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2022)
Biogas or biomethane, resulting from the biological treatment of organic matter by anaerobic digestion, is a renewable energy source used for electricity production, heating and in transportation and can substitute fossil gas. Therefore, biogas production is described as a sustainable strategy for reducing anthropogenic greenhouse gases (GHG). However, the positive environmental impact depends in particular on emissions that might occur within the biogas production and utilization chain. Although numerous scientific studies investigated CH4 emissions from biogas plants, there is still a lack of reliable and representative emission data. As stated in the United Nations Framework Convention on Climate Change, the member countries are obliged to report their national GHG inventories according to the Intergovernmental Panel on Climate Change (IPCC) guidelines.

Energetic Utilization of Organic Waste and Residuals in Germany
© Lehrstuhl fĂĽr Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2014)
Biomass is currently the most important renewable energy source in Germany. Approximately two-thirds of the available residue potential in Germany is already used energetically, the thermal recovery with the use of waste wood predominates (Nelles et al. 2013). The energy potential of relevant organic waste and residuals such as waste wood (8%), straw (7%), manure (6%), industrial waste wood (4%) as well as bio- and green waste (1%) is estimated by the Agency for Renewable Energy up to 383 PJ/a in 2020 (AEE 2013).

Biomethane in Europe - can western success spread east?

Already 157 plants are injecting Biogas into the gas grids of Europe. Biomethane initiatives such as new support schemes as in France and the UK should help to stimulate the market.

The swedish voluntary Agreement for control of methane emissions from Biogas plants
© European Compost Network ECN e.V. (6/2012)
Swedish Waste Management Association has set up a voluntary agreement for control of methane emissions frombiogas and upgrading plants, starting in the year 2007. There were a number of reasons to start this system, mainlyenvironmental (GHG emissions and odour), economical and safety issues, but as important was to show that the biogasindustry acts responsibly and is pro-active regarding these issues, especially in relation to authorities. The voluntaryagreement system has been reviewed once and is currently set up in two parts; internal routines for leak detection andemission measurements performed every 3 years by an external consultant. Further Authors: H. Hellström - SP Technical Research Institute of Sweden A. Blom - Swedish Waste Management Association

Greenhouse gas Monitoring for optimization of process Efficiency of Biogas plants
© European Compost Network ECN e.V. (6/2012)
Within the research project "KLIMONEFF" modern optical remote sensing (ORS) technology is applied as aninnovative approach to detect methane losses of diverse parts of biogas facilities in order to reduce their greenhouse gas(GHG) losses and optimize their energy efficiency. An Austrian biogas plant has, therefore, been selected to quantifythe GHG emissions of the entire plant but also methane losses (methane loads) from various plant components for therepresentative period of one year.

External influences on the energy efficiency of composting plants
© European Compost Network ECN e.V. (6/2012)
With regard to energy efficiency as a major tool to reduce the use of fossil energies and to enable the conversion to a sustainable energy system, also biological waste treatment technologies have to improve their specific energy efficiency i.e. the energy used for a specific amount of biological waste utilised. To increase the energy efficiency of composting plants two general approaches seem to be viable.

A PV giant alongside the Alps
© Editorial OMNIMEDIA S.L. (5/2012)
The Curbans photovoltaic power facility has a total output of 33 MWp with approximately 145,000 photovoltaic panels producing 43,5 million kilowatt hours of renewable energy each year. This is equivalent to the annual electricity consumption of 14,500 households (excluding heating) and, compared with a fuel oil power plant, sparing close to 120, 000 metric tons of CO2 emissions annually. The plant, with an investment of 100 million Euros led by the French giant GDF SUEZ, has been fully executed as an EPC by the Spanish engineering company Maetel, a company belonging to the ACS Group’s industrial division, and it is currently the highest capacity facility built in France.

Kurzumtriebsplantagen statt Raps
© Eigenbeiträge der Autoren (11/2011)
Innerhalb von 10 Jahren hat sich die Zahl der Pelletheizungen in Deutschland von 3000 auf 15000 erhöht. Biomasse wird immer mehr in Energie umgewandelt. Raps für Biodiesel wächst auf fast einem Millionen Hektar, Kurzumtriebsplantagen gibt es in Deutschland erst auf 3000 Hektar. Eine von vielen Möglichkeiten zur Nachnutzung von Deponien wie sie im EU Projekt SULFANET untersucht wurden.
