Background

7.1 According to the Commission, growth is still accompanied by increasing amounts of waste, and it says that one of the Community's strategic goals is to reduce the resultant negative impacts (in terms of unnecessary losses of materials and energy, and damage to health, the environment and quality of life). It notes that waste management is already governed by a substantial body of regulation, but that there remain opportunities for further improving the management of some major waste streams, including bio-waste (defined as biodegradable garden and park waste, and food and kitchen waste), in the light of recent technological progress and research results. In particular, it points out that very different national policies apply to bio-waste management within the Community, and says that consideration should be given to whether national action is sufficient, or Community action is needed. It has therefore sought in this Green Paper to explore the various issues which arise, and to invite views, and so prepare the ground for an Impact Assessment. In doing so, it is also fulfilling a remit contained in the revised Waste Framework Directive (2005/281).

The current document

7.2 The Commission observes that the total annual bio-waste in the Community is put at between 76.5 and 102 million tonnes of food and garden waste in mixed municipal waste, and up to 37 million tonnes from the food and drink industry, with two major streams — green waste (which usually comprises wood and 50-60% water) and kitchen waste (which contains up to 80% water, but no wood). It also points out that, in addition to prevention at source, the waste management options available include separate collection, biological treatment (including anaerobic digestion and composting), mechanical-biological treatment, incineration and landfill, with the environmental and economic implications of each depending on local conditions. Within this framework, it notes wide differences between Member States, with three main approaches having been identified — heavy reliance on incineration to divert waste from landfill, accompanied by a high level of material recovery and biological treatment; high material recovery rates accompanied by composting and mechanical-biological treatment, but relatively low incineration; and reliance on landfill, particularly in a number of the new Member States.

7.3 The Commission goes on to review the Community legal instruments relating to the treatment of bio-waste. In addition to the general requirements laid down in the Waste Framework Directive, these include the Landfill Directive (1999/31/EC) which requires the diversion of biodegradable bio-waste from municipal landfills; the revised Integrated Pollution Prevention and Control Directive (which applies to installations biologically treating more than 50 tonnes of organic waste a day); the Waste Incineration Directive; and the Animal By-Products Regulation (where such by-products are treated in composting and biogas plants). These are accompanied by a number of measures relating to the use of bio-waste, covering in particular the use of compost in organic farming and in energy recovery, notably in relation to renewable electricity and biofuels. Also, since incinerated bio-waste is regarded as a carbon-neutral source of energy, it is covered by the Renewable Electricity Directive (2001/77/EC), and by the current proposed Directive on the promotion of energy from renewable sources.[41]

7.4 The Green Paper then focuses in more depth on the environmental, economic and social issues related to bio-waste management. As regards the environmental impacts, it points out that the decomposition of biodegradable waste in landfill gives rise to emissions of greenhouse gases, notably methane (although these are expected to reduce as a result of the Landfill Directive), may give rise to odours and an adverse visual impact, and involve an irrecoverable loss of resources and land; that incineration may provide carbon-neutral energy as an alternative to fossil fuels, but that the efficiency of current incinerators varies considerably, with its main impacts arising from airborne emissions, the loss of organic matter and other resources, and the disposal of ashes etc; and that, although biological treatment involves some limited emissions of greenhouse gases and volatile organic compounds, it can provide potential agricultural benefits (subject to proper control being exercised over input quality to avoid contamination and the accumulation of hazardous substances). It suggests that there seems to be no single environmentally best option for the management of biodegradable waste diverted from landfills, with the balance depending upon a number of local factors, such as waste collection systems, climate conditions, and the potential use of the various waste derived products. Consequently, it says that strategies for the management of this waste should be determined "on an appropriate scale", based on a Life Cycle Assessment.

7.5 As regards the economic impacts, the Commission notes that the capital and operating costs of municipal waste management and the biological treatment of waste depend upon multiple factors[42] and vary regionally and locally, making it difficult to make meaningful comparisons. However, it says that landfill is usually regarded as the cheapest option, although this may well change if the Landfill Directive leads to increased costs and to a rising awareness of the "real" long term costs involved; that incineration requires higher investment, but can offer good economies of scale, whilst avoiding changes to existing municipal waste collection schemes and bringing in revenue from energy recovery; and that the diverse range of biological treatments generally require good quality waste, and hence gives rise to separate collection costs. It also notes that establishing separate collection schemes present a number of challenges, such as the re-design of collection systems, changing consumer habits, the identification of suitable areas, and problems in matching the supply of waste with the market for its subsequent recycled use.

7.6 The Commission also refers briefly to the social and health impacts, noting that, although increased recycling of bio-waste is expected to have limited impacts on employment, new jobs may be created in waste collection and in small composting plants. However, it says that there is a general lack of quality data on the health impacts of the various options, but that there are no apparent ill effects on people living near municipal waste management facilities or incineration plants. On the other hand, small risks of birth defects have been identified near landfill sites, and of bronchitis near to composting sites.

7.7 The Green Paper concludes by seeking views on the following policy areas:

  • possible new bio-waste prevention action at the EU level;
  • the need for further restrictions on biodegradable waste to landfill, beyond those of the Landfill Directive, what form these might take and whether they should be at Community or national level;
  • what measures might be taken to encourage specific bio-waste management options such as anaerobic digestion and composting, and whether life-cycle studies should be more widely used to evaluate options;
  • measures to improve energy recovery;
  • the promotion of bio-waste recycling through: target setting, rules for quality and use of compost, measures to promote separate bio-waste collections — in each case with measures at Community or individual Member State level;
  • the contribution of composts and digestates to soil improvement and the setting of standards on when such materials have completed the recovery process and cease to be waste;
  • the setting of operational standards for bio-waste plants treating less than 50 tonnes per day (and thus not currently covered by the revised IPPC Directive);
  • research and development into new, alternative ways of treating bio-waste, and possible regulatory obstacles.

The Government's view

7.8 In her Explanatory Memorandum of 18 February 2009, the Minister of State (Farming and the Environment) at the Department for Environment, Food and Rural Affairs (Jane Kennedy) said that the Green Paper is important to the UK since the management of bio-waste is currently undergoing great change, and that, although infra-structure and collection practices remain under-developed, the potential for energy and resource conservation was large. She added that the paper raised several issues of interest to the Government, and that it would be drawing up its response over the coming weeks, in consultation with relevant stakeholder, and submitting comments to the Commission before the consultation period ended on 15 March 2009. She added that the Commission had stated its intention to present its analysis of the responses in late 2009 with, if appropriate, proposals and/or initiatives for a Community strategy on the management of bio-waste.

7.9 Since we felt it would be sensible to take into account the views expressed by the UK to the Commission, we decided to await these before considering our Report to the House. The Minister has now enclosed a copy of the UK's response with a letter of 31 March 2009. That response says that:

  • the UK broadly welcomes the Green Paper as a fair summary of the issues, and, like most Member States, is already making very significant changes to the way it manages certain bio-waste streams in response to the Landfill Directive and in drawing up a strategy to meet its renewable energy targets;
  • it believes that the prevention of waste, including bio-waste, is far more resource and energy effective than subsequent management or treatment, and that it would expect bio-wastes to be included in Member States' waste prevention programmes: however, it believes that public information campaigns need to be alert to national sensitivities, and would not therefore work at a European level, and that the same applies to decisions on how to collect waste and such issues as the role of home composting;
  • consumer responses to date marking of food can have an important impact on the generation of food waste, and that there is therefore a need to clarify Community legislation in this area;
  • the UK has found its targets under the Landfill Directive to be extremely challenging, and any changes to the existing regulatory framework for bio-waste need to be justified by a thorough impact assessment (though it retains an open mind on the possibility of further measures, such as a ban on the types of waste which could be disposed of in this way);
  • the most appropriate option for the treatment of bio-waste will depend upon the location, the waste feedstock used, and the availability of suitable destinations for treated material, with the best option usually being decided on a case by case basis: however, the UK believes that anaerobic digestion may often be the best option for bio-wastes such as food waste, but that composting still has an important role to play in the treatment of biodegradable waste;
  • there is a need to encourage the use of good quality compost on land, but that this should be done through market "pull", rather than legislative "push", bearing in mind also that varying soil characteristics make it difficult to set prescriptive Community-wide standards: each Member State should therefore be free, within an overall Community framework, to set its own parameters;
  • although the UK believes that anaerobic digestion should normally be the preferred option for the management of wet biodegradable wastes, and is seeking to increase its use, this is currently limited; however, the separate collection required is expensive, and Member States should be free to make their own decisions, where this is supported by sound research, including life-cycle assessments (though it would be helpful if the Commission were to clarify the level at which such assessments should be used, since this will affect their feasibility and the validity of the results).

Conclusion

7.10 This Green Paper provides a useful over-view of the issues which arise in relation to the management of bio-waste, and of the various options facing the Community and Member States, and, for that reason, we are drawing it to the attention of the House. However, we note that it is intended primarily to stimulate discussion, and that the Commission proposes to present later this year an analysis of the responses it receives, together with proposals for a Community strategy in this area, if that is thought to be appropriate. We also note that the Government regards the Green Paper as providing a fair summary of the issues involved, and has itself put in various comments to the Commission.

7.11 In view of this, we do not believe that any further consideration of this document by the House is required at this stage, and we are therefore clearing it.
