Managing organic wastes

Synonyms:

Controlling use of biological waste

Description:

Organic wastes can be treated to produce compost (using aerobic treatment) or a biogas (using anaerobic treatment).

Context:

Separate collection of biological waste has become an important aspect of the closed substance cycle. It concerns materials arising in conjunction with human nutrition, either as kitchen waste or as waste from food processing. It also includes grass cuttings and garden waste. In total, between five and six million tonnes of biological waste in Germany are processed into high quality compost in approximately 500 composting plants employing some 4,000 people. For the Federal Republic as a whole, the total potential for biological waste is estimated at between ten and twelve million tonnes.

Implementation:

The German Government passed its [Biological Waste Ordinance] in 1997. The Ordinance contains stringent provisions governing the hygiene properties and pollutant levels of biological waste and compost, as well as taking agricultural requirements into account. Under the collective term "biological waste", the Ordinance basically covers all treated or untreated biodegradable waste applied to agricultural and horticultural areas. In particular, this includes compost from biological waste. The maximum amount for application is 20 or 30 tonnes per hectare over three years, depending on the quality criteria adhered to. Compost heaps in private gardens and allotments are not affected by the Ordinance.

About the Encyclopedia

The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature.

The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.

About UIA

The Union of International Associations (UIA) is a research institute and documentation centre, based in Brussels. It was established in 1907, by Henri la Fontaine (Nobel Peace Prize laureate of 1913), and Paul Otlet, a founding father of what is now called information science.

Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
