Uncontrolled spreading of waste materials leads to health problems and environmental damage. To prevent these problems a waste management infrastructure has been set to collect and dispose of the waste, based on a hierarchy of three principles: waste prevention, recycling/reuse, and final disposal. Final disposal is the least desirable as it causes massive emissions, to the atmosphere, water bodies and the subsoil. The emission of methane to the atmosphere is an important source of greenhouse gasses. Organic waste therefore gets a lot of attention in waste management, which for Europe can be illustrated by the issue of the Landfill Directive (99/31/EC) and the Sewage Sludge Directive (86/278/EEC) Proper treatment of organic waste may however turn this burden into an asset. In particular, biological treatment may help in developing more effective resource management and sustainable development. The following advantages may be listed: - The greenhouse effect is tackled as methane emissions from landfilling are prevented - Soil quality can be restored or enhanced by the use of compost in agriculture - Compost may replace peat in horticulture and home gardening, reducing greenhouse emissions and wetland exploitation - Anaerobic digestion has the additional benefit of producing biogas that may be used as a fuel - Pesticide use can be reduced by proper use of the disease suppressive properties of compost As a result of this linkage of the field of waste management to the societal production system at large, there is a need of involvement of many different disciplines, not only natural sciences but also economical, policital and management sciences, product specialists, etc. Although most people involved will agree with such a statement, in practice we still see a lot of fragmentation. As an example there is still insufficient exchange between agronomist working with compost and technologist working with the composting process. Resource Recovery and Reuse in Organic Solid Waste Management disseminates at advanced scientific level the potential of environmental biotechnology for the recovery and reuse of products from solid waste. Several options to recover energy out of organic solid waste from domestic, agricultural and industrial origin are presented and discussed and existing economically feasible treatment systems that produce energy out of solid waste and recover useful by-products in the form of fertiliser or soil conditioner are demonstrated. The potential of environmental biotechnology is highlighted from different perspectives: societal, technological and practical.
