Waste categorisation

Emissions to land Degussa-Huls states that a comparison for the data for 1997 and 1998 with that from previous years is impossible owing to the changes in waste categorisation. 

Various aspects of transport of solid waste have been dealt in IAEA Safety Series No.6 [5]. To facilitate formulation of transport requirements and regulations, specific categorisation schemes have been adopted for shipping purposes e.g. ... 

Mr. Kazakov discussed problems associated with contamination from the Chernobyl nuclear accident. The first problem is in characterising what portion of the contaminated material in the exclusion zone should be considered radioactive waste and how to deal with it remove it or possibly use materials for construction. Consideration of the extent to which contaminated materials should be removed, as radioactive waste, presents a problem as well. This is related to the second problem in properly characterising the total inventory of the radioactive waste. The waste is characterised at temporary locations of radioactive waste (TLPRW) and radioactive waste burial sites (RWBS). Although there is a great deal of documented information on the locations, volumes and activities, it is unclear whether to categorise the radioactive waste by specific activity, volume or presence of transuranic and fissionable elements in the radioactive waste.

The solid radwaste system is described in detail in Section 11.4 of Reference 15.14 and summarised in the Enviromnent Report. The system categorises solid radioactive waste as high-level waste (HLW), intermediate-level waste (ILW), or low-level waste (LEW) (see Enviromnent Report, Figures 3.4-1 3.4-2). The solid radwaste system comprises a radwaste building for handling and sorting LLW and an LEW buffer store area. 

Selection of indicators used in LCA studies on biodegradable polymers some of these indicators are categorised by Udo de Haes [47] as Pro Memoria Categories . Udo de Haes defines these as truncated flows that cannot be allocated to the categories extraction or emissions. Examples named are energy and waste ... 

It seems inevitable, however, that recycling practice will involve a combination of all options. This is categorised as the Best Practical Environmental Option (BPEO) by waste management specialists and is defined as ... 

To assist in the marketing of tyre-derived rubber products, a categorisation system has been established as part of the UK Waste Resources Action Programme (WRAP) Quality Protocol (Section 6.4.1.5), which will help avoid possible confusion in the use of terms such as rubber crumb and rubber powder . The categories and definitions that are in the protocol are shown in Table 6.1. 

MFCs can produce electricity from various organic sources, such as waste-waters, slugs and soils. According to the substrate resources, MFCs are categorised into three types (i) MFCs producing electricity from wastewaters.
