Urban biomass from green areas is a potential resource for bioenergy recovery, which is widely unused. Different types of organic material (e.g., grass, leaf litter) usually occur in mixtures due to common collecting practice. Forty samples of grass, leaf litter (genera: Acer, Quercus, Tilia), and mixtures of both, containing one third grass or leaf litter, were investigated to evaluate the effect...
Urban leaf litter occurs in significant, yet unknown, quantities and is regularly disposed of or composted. Instead, it could be widely used as a regional resource for solid fuel production. Samples of five tree genera (Acer, Aesculus, Fagus, Tilia, Quercus) were taken after leaf abscission and analyzed for elemental composition (C, H, N, S, Ca, Cl, Cu, K, Mg, Mn, Na, P, Zn) and ash slagging behavior...
