Management of Urban Organic Solid Waste Applied in Romanian Metropolitan City

This paper explains the interest in urban organic solid wastes, the relevance of these wastes to municipal solid waste management, the main ways in which organics are reused, and the problem that arise from the wish to ensure safe and effec tive reuse as part of sustainable development in cities in Romania. Wastes are substances resulting from biological or technological processes that can no longer be used as such, some of which are reusable. Dangerous substances are any substance or product which, when used in apparently non-hazardous quantities, concentrations or conditions, presents a significant risk to humans, the environment or material goods (eg explosives, oxidizing, flammable, toxic, harmful, corrosive, irritant, mutagenic. Urban administrations nowadays are seeking ways to divert organic wastes from municipal solid waste streams for a variety of reasons, as noted below. Recommenda tions are made for separation at source so that safe composting can be carried out. Private companies are being encouraged to undertake composting, often via forms of public-private partnerships. More attention is being paid to the role of non-govern mental organizations in promoting citizen awareness of organic waste issues, and co-operation with separation at source. This paper draws attention to the many informal ways that organic wastes are currently reused, which are rarely taken into account in official plans for managing organic wastes.
