Waste as resource

Abstract

In the past waste management proved to reduce CO2 emissions both by reuse of recyclables and energetic utilization of substrates with high available energy load. This paper provides an overview about biomass originating from waste. Therefore the biogenic waste fractions are classified by origin. In this manner one can separate the origin of biomass in forestry, agriculture, landscape maintenance, municipal solid waste and industrial waste. Subsequent chemical and physical parameters were described to assess the applicability for thermal utilization as well as for the production of biokerosene. The focus is on calorific values, ash and water content as well as on inhibiting parameters such as sulfur, nitrogen and heavy metals. Based on this, the second part of this paper describes the energy potential of the ubiquitous occurring biomass originating from waste. Therefore the incidence of each waste fraction is related to a specific energy potential respectively calorific value. Due to this the theoretical applicability of waste as feedstock for the production of biokerosene can be assessed.
