Status and trends for biomass use and consequences for waste management - the example of Germany
While separate collection and treatment of organic waste in Germany had a magnitude of 100.000 Mg in 1985 it currently extends to 8.2 Mio. Mg of which about 50% each refers to biowaste and green waste respectively. However, a further potential of 8 million Mg of organic waste collected with other residual waste still exists. Rapidly increasing costs for the treatment of residual waste coupled with indicative results showing improved success rates for sorting of valuable matters from municipal wastes enhance chances for increased rates of separate collection of organics wastes. On the utilization side trends indicate more differentiated pathways for material and energetic use of biowaste. Such developments are already visible at a wide range of treatment sites where composting facilities expand their utilization options towards fermentation and combustion of suitable fractions of organic wastes. The global issues, energy and climate protection drive the political and legal frame conditions towards a combination of material and energetic use of biomass.
