11、 document (CEN/TR 14980:2004) has been prepared by Technical Committee CEN/TC 343 “Solid recovered fuels”, the secretariat of which is held by SFS. This document has been prepared under the Mandate M/325 to CEN on Solid Recovered Fuels 1 to provide the European Commission with a report on the relati

12、ve difference between the biodegradable and the biogenic fraction of waste in order to decide whether there is a need to develop two different standards or only one. B55EB1B3E14C22109E918E8EA43EDB30F09CC9B7EF8DD9NormCD - Stand 2007-03CEN/TR 14980:2004 (E) 4 Introduction In a long term perspective of

13、 Sustainable Development, it is crucial to use resources as efficiently as possible. Natural, as well as financial, resources use should be optimised to limit as far as possible the effects on human health and on environment, while creating wealth more easily accessible to all fractions of the world

14、 population. In a medium term perspective, climate change effects due to greenhouse gas emissions from human activities should be properly addressed. Shorter term issues such as energy security of supply remain a permanent concern as well. Solid Recovered Fuels (SRF) are fuels prepared from non haza

15、rdous waste to be utilised for energy recovery in waste incineration or co-incineration plants regulated under Community environmental legislation 1. SRFs play an important role in the EU Community energy policy (see CEN/TR 14745:2003 2). The cost benefit analysis has shown that the use of SRF contr

16、ibutes to the reduction of greenhouse gases. The use of SRFs is particularly important in sparsely populated areas. It also serves a means to meet the targets of the Landfill Directive 3 by reducing landfilling of biodegradable waste. Solid Recovered Fuels (SRF), by replacing e.g. fossil fuels and l

17、imiting the volumes of waste sent to landfills, can contribute to increasing resource efficiency. If based on biomass, their use will prevent emissions from fossil carbon into the atmosphere and decrease correspondingly greenhouse gases emissions from anthropogenic activities; biomass-based SRF is a

18、 source of storable solar energy. The Commission Decision of 29/01/2004 establishes guidelines for monitoring and reporting of greenhouse gas emissions pursuant to Directive 2003/87/EC (7). Due e.g. to the existence of legislative measures in favour of electricity based on renewable resources, there

19、 is a need for clear commonly agreed terminology and test methods for SRF. To be able to make any decisions on test methods needed for the determination of the biodegradable fraction and the biogenic fraction of solid recovered fuels it is necessary to have clear definitions on these terms. The term

20、s biodegradable and biogenic do not mean the same thing. Biodegradable relates to the degradation of a material, while biogenic relates to its formation and origin. Definitions in relevant EU directives have been taken into consideration and are listed in Chapter 4 “Definitions on biodegradable, bio

21、genic and biomass”. In EU directives 2001/77/EC 4 on the promotion of electricity produced from renewable energy sources in the internal electricity market (RES-E), biomass is identified as a renewable energy source and is defined as the “biodegradable fraction of products, waste and residues from a

22、griculture (including vegetal and animal substances), forestry and related industries, as well as the biodegradable fraction of industrial and municipal waste”. As this definition concerns only the degrading of biomass an additional clarification concerning its short-cyclic origin was needed. The te

23、rm biogenic is used in the context of the Kyoto protocol. Requirements on the definitions: a) The definitions need to be as clear as possible. b) The definitions need to comply with the difference between short-cyclic organic matter such as wood and long-cycle carbon based1)organic matter such as co

24、al and petroleum based plastics. When the regene-ration of a fuel takes thousands of years it cannot be considered as participating to the short C-cycle and is therefore no longer short-cycle carbon based2). 1)Long C-cycle takes thousands of years to close the loop C back to C (fossilisation). 2)Sho

25、rt C-cycle take a few years (one to a few hundreds of years) to close the loop (short term renewable resources) B55EB1B3E14C22109E918E8EA43EDB30F09CC9B7EF8DD9NormCD - Stand 2007-03CEN/TR 14980:2004 (E) 5 c) The results of the definitions need to be manageable in practical situations such as laborato

26、ry analyses. In Chapter 4 “Definitions on biodegradable, biogenic and biomass”, definitions for the purpose of this report are given. With these definitions as a base, different methods of analysis are discussed. To be suitable in practice a method has to give a good approximation of the biodegradab

27、le and/or the biogenic fractions, be reasonably fast and not too expensive in order to define the biomass content of SRFs.

28、ction and the biogenic fraction of solid recovered fuels prepared from non-hazardous waste for energy recovery and whether there is a need to develop two sets of standards or only one set for the determination of these fractions in order to define the biomass content of SRFs. 2 Normative references

46、urned for energy purposes biomass is referred to as biomass fuel. 5 Determination of biodegradable and biogenic fractions of waste 5.1 General The terms biodegradable and biogenic do not mean the same thing. Biodegradable relates to the degradation of a material, while biogenic relates to its format

47、ion and origin. Technically and scientifically “biodegradable” is not equal to “biogenic” and neither is relevant as a definition of “biomass”. 5.2 Biodegradable fraction A biodegradable material can be degraded by living organisms, usually micro organisms, depending on available organisms, physical

48、/chemical environment and time. Generally speaking materials based on biomass, provided they have not been modified to alter their biodegradability, are much more readily biodegradable than materials based on fossil raw materials as far as these latter have not been designed for being easily biodegr

49、adable. Biodegradation of commonly used plastics is very slow. For the purpose of CEN/TC 343, biodegradable material can be roughly regarded as being the same as biomass as defined above. A test method for the determination of biomass could thus be used keeping in mind that it gives only a rough estimation. Test methods relying on measurement of biological degradation are very time consuming and very costly. Such a determination takes several months before the results are available. For practical use in the case of solid re
