The use of biogas production as a complementary solution to conventional and second-generation ethanol production in Brazil may increase the energy produced per hectare in the sugarcane sector. Herein, it was demonstrated that through ensiling, energy cane can be conserved for six months; the stored cane can then be fed into a continuous biogas process. This approach is necessary to achieve year-round biogas production at an industrial scale. Batch tests revealed specific biogas potentials between 400 and 600 LN/kgVS for both the ensiled and non-ensiled energy cane, and the specific biogas potential of a continuous biogas process fed with ensiled energy cane was in the same range. Peak biogas losses through ensiling of up to 27\% after six months were observed. Finally, compared with second-generation ethanol production using energy cane, the results indicated that biogas production from energy cane may lead to higher energy yields per hectare, with an average energy yield of up to 162 MWh/ha. Finally, the Farm²CBG concept is introduced, showing an approach for decentralized biogas production.}, language = {en} } @article{Thielemann1997, author = {Thielemann, Frank}, title = {Chancen durch Online-Dienste?}, series = {OP DruckMagazin. 39 (1997), H. 1-2}, journal = {OP DruckMagazin. 39 (1997), H. 1-2}, isbn = {0030-0594}, pages = {26 -- f.}, year = {1997}, language = {de} } @article{SchwarzerSilva2008, author = {Schwarzer, Klemens and Silva, Maria Eugenia Vieira da}, title = {Characterisation and design methods of solar cookers / Schwarzer, Klemens ; Silva, Maria Eugenia Vieira da}, series = {Solar energy. 82 (2008), H. 2}, journal = {Solar energy. 82 (2008), H. 2}, isbn = {0038-092X}, pages = {157 -- 163}, year = {2008}, language = {en} } @article{HelsperMoelter1991, author = {Helsper, Christoph and M{\"o}lter, W.}, title = {Characteristics of a Nebulizer with Cyclone Preseparator / M{\"o}lter, W. ; Helsper, C.}, series = {Aerosols, their generation, behaviour and applications.
