Managing biowaste and promoting sustainability - profiling community composting

The voluntary and community waste sector makes an important contribution to waste objectives (Williams et al, 2006). The community composting sector would appear to be leading the development of innovative biowaste collection and processing systems in areas unsuitable for traditional kerbside. Such schemes can contribute to developing local areas by improving local soils and green spaces as well as diverting waste from landfill. However, this is often only part of the story. Well managed community activity has huge potential for providing work and volunteering opportunities, as well as bringing people together and improving skills, knowledge and self-confidence. Considered collectively these factors may contribute to local sustainability more effectively than reliance on meeting particular targets. Although there is some anecdotal and financial evidence for the growth in, and diversity of, community composting, there is very little comprehensive data that draws together the activity of the sector as a whole. The paper addresses this gap by presenting findings from a national survey profiling community based composting. Results show that a range of activities fall under the umbrella of community composting and these include: collecting / receiving and processing material, running education campaigns, promoting home composting and facilitating others to develop / promote community composting. The survey recorded over 100 groups actively engaged in at least one of these activities with many involved in more than one. Overall 80% of groups are involved in collecting and composting material and 20% are involved in composting related activity other than collecting and composting, such as educational and promotional activities. The sector has a large potential for providing work and volunteering opportunities and results indicate over 1,300 volunteers, trainees and staff involved in community composting. In addition, most groups (68%) carry out composting alongside other waste and recycling activities or, more commonly, alongside non-waste activities such as community gardens, city farms, local food production, day and residential services and work integration schemes. These activities may bring about positive environmental impacts and social benefits over and above quantities of material diverted from landfill, and these benefits often cut across different policy agendas. Knowing and understanding these impacts and benefits is important in understanding the role of the community composting sector. In addition to results from profiling the sector, this paper will also present findings from participatory research with groups to develop ways to better understand and demonstrate the impacts of their work

Enhancing sustainable biowaste management in the UK: the role of the commercial and community composting sectors

This paper considers the different roles of the commercial and community composting sectors in contributing to sustainable biowaste management in the UK. Legislation and policy have driven the rapid development of a diverse composting sector. The next section sets out this policy context. This is followed with an analysis of the growth in, and characteristics of, the commercial composting sector and then the community composting sector. It is contended that both sectors have different strengths in contributing to sustainable biowaste management. For commercial composting this is based around large-scale composting and quality products, for the community sector this is based around services in difficult collection environments, local sustainability, promoting social cohesion and building stronger communities. The extent to which the benefits from the commercial and composting sectors will be realised in the future will depend on whether the sectors can develop synergistically and the extent to which this is encouraged by national and local policies

Unlocking the potential of community composting: Full project report

Community based composting schemes can make valuable contributions to the development of local infrastructure and amenities by improving soils and green spaces in addition to diverting waste from landfill. Furthermore, well managed community activities have potential for providing work and volunteering opportunities, as well as bringing people together and improving skills, knowledge and self-confidence. Considered collectively these factors may contribute to local sustainability more effectively than focusing on meeting particular waste related targets. Although there is some anecdotal and financial evidence for the growth in, and diversity of, community composting, there is very little comprehensive data that draws together the activity of the sector as a whole. This research set out to understand and assess the current and potential role of the community composting sector in achieving Defra’s waste related targets and Government’s other wider environmental and social objectives. Thus this research is timely both in terms of establishing what has been achieved in the community composting sector to-date and in terms of possibilities for future achievements

Evaluation of Charge Storage and Decay in Spacecraft Insulators

Two reports discuss methods for evaluating the magnitude of electrostatic charging that occurs in spacecraft dielectric materials (in particular, polyimides) during prolonged exposure to radiation in outer space. The reports describe experiments on the electrical resistivities and charge-storage properties of polyimide specimens in a dark, evacuated environment, both before and after 5-megarad exposures to rays from cobalt-60. The experiments were designed to measure these properties not under standard conditions prescribed for testing dielectrics in air but, rather, under conditions approximating those in the intended spacecraft applications. The results of the experiments showed that the electrical resistivities of the insulations as determined under these conditions are greater, by a factor of roughly a thousand, than those determined under the standard conditions and that the gamma irradiation reduced resistivities marginally

Understanding diversity in community composting: it's all in the mix

The emergence and development of a coherent and defined community composting sector, as with the commercial composting sector, is relatively new. There is some anecdotal and funding support evidence for the growth in, and diversity of, community composting, but there is very little comprehensive data that draws together the activities of the sector as a whole. This paper starts to address that gap by presenting a summary from a national survey on the nature of the community composting sector and shows that it comprises groups and organisations involved in a diverse range of activities. It also presents findings from participatory workshops with community composting groups and their stakeholders exploring the extent to which projects contribute to individual and community change

Aggregate earnings and stock market returns: the good, the bad, and the state-dependent

Prior research documents a negative aggregate earnings-returns relation. In contrast, we posit that the sign of the relation varies, depending upon the macroeconomic and financial market conditions that exist in the earnings announcement quarter. We argue that the existing macroeconomic and financial market conditions influence market participants’ frame of reference, which in turn affects whether they interpret aggregate earnings surprises to be informative about the expected inflation component of the discount rate, the market risk premium component of the discount rate, or aggregate future cash flows. Consistent with this, we find that the sign of the aggregate earnings-returns relation changes numerous times across our sample period. We also find that market participants interpret aggregate earnings to be informative about changes in expected inflation (market risk premium) when the sign of the aggregate earnings-returns relation is negative (positive). Finally, we identify macroeconomic and financial market conditions under which the aggregate earnings-returns relation is more (less) likely to be negative (positive)

No. 4 - Agriculture and the WTO: Subsidies in the Cross Hairs

September 2003 saw trade talks pursuing the Doha Development Agenda at the Cancún WTO Ministerial Meeting collapse, primarily over the disagreements between rich and developing countries regarding agriculture. Despite the great pessimism that ensued, on August 1, 2004, WTO negotiators from 147 countries announced a breakthrough in negotiations to liberalize trade in agricultural products. The most striking aspect of this new framework agreement is the proposed elimination of agricultural subsidies by rich countries in return for developing countries opening up their markets to more imports. At the same time, WTO dispute resolution panels have delivered stunning decisions against the U.S. cotton subsidy program and the European Union\u27s sugar subsidies. Clearly agriculture trade policy will be a pivotal issue determining the failure or success of the Doha round. This conference featured noted experts from senior levels of government, the private sector, and the legal profession addressing current developments in multilateral negotiations and the WTO cases on agriculture and analyzing their impact on the future of the world agricultural market. It was presented on November 16, 2004, at the University of Georgia School of Law by the Dean Rusk Center–International, Comparative, and Graduate Legal Studies and the College of Agricultural and Environmental Sciences

Ethics and the Public Administrator

This article provides an overview and analysis of the practical problems of developing and implementing a code of ethics for public administrators. The article addresses three key issues: (1) What are public ethics and where do they come from? (2) What are the central ethical issues facing public administrators? and (3) Are there practical tools and guidelines to assist public servants to be both ethical and effective public managers? The article concludes with a plea for consideration of ethical issues, and it presents five general ethical principles for public administrators
