Among the alternative fuels, biogas has the best ecological balance. With the fuel obtained from manure, greenhouse emissions could be reduced by up to 90 percent.
The best ecological balance among the alternative fuels has processed biogas. With this liquid manure-based fuel, greenhouse emissions could be reduced by around 90 percent, reports the natural gas vehicles sponsoring group in Berlin, citing a study by the Swiss Federal Technical Universities (EMPA). The study was carried out on behalf of the Federal Government of Bern. Refined biogas is also called biomethane or bio natural gas and is suitable as a fuel for all natural gas vehicles.
Different savings
Biofuels mostly consist of renewable raw materials - but according to the information they have, their ecological balance is quite different. The reasons for this are factors such as cultivation, processing and also transport. The production of biofuels from residual and waste materials offers clear advantages over production from renewable raw materials - agricultural cultivation has a negative impact on their environmental balance. Nevertheless, CO2 savings of 30 to 50 percent could still be achieved with bio natural gas from vegetable raw materials. According to the study, the production of bio natural gas from wood leads to CO2 savings of around 70 percent. (dpa)
