Analysing the hindrances to the reduction of manufacturing lead-time and their associated environmental pollution
Manufacturing Lead-Time (MLT) is the total time required to process a given product through a plant. Long MLT is the major cause of inefficient manufacturing, since it generates large amount of wastes and creates considerable environmental burden. In the past, a large amount of environmental pollution has been generated by manufacturing industries, most of which come from inefficient practices ...

A statistical approach to predict waste generation rates to support recycling programmes
Construction wastes constitute material with high potential for on-site reuse and off-site recycling; however, a significant fraction of this waste is still directed to landfills. Inability to predict time-dependent and activity-specific waste generation rates is one of the barriers to successful implementation of a construction waste minimisation programme. This paper discusses the development ...

Implementing environmental improvements in a manufacturing context: a structured approach for the precast concrete industry
In common with other industries, most of the measures and solutions employed by companies in the ?2 billion UK precast concrete manufacturing sector are linked to profitability. The concept of sustainability adds new dimensions as social progress and environmental protection become end goals in themselves, rather than objectives to achieve economic growth. This paper explores the nature of the ...

EU Focus on Waste Management
Abstract Some topics are of particular concern to many European citizens. One of these is the worrying increase of waste production. The Community, indeed, generates each year around 2,000 million tonnes of waste. Over 40 million tonnes is classified as hazardous. Over the last six years, the amount of waste generated grew by 10 % a year. It is clear that we must stop and reverse this trend if ...

Waste dynamics, decoupling and ex post policy effectiveness: evidence from the EU15
This paper provides a comprehensive analysis of municipal and packaging waste generation dynamics, based on panel data for the EU15. The evidence provides some valuable policy implications since it analyses the extent to which decoupling has occurred for the two waste streams and if and how effectively EU waste policy has influenced the waste generation-income relationship since 1995. We ...

Life cycle assessment of waste prevention in the delivery of pasta, breakfast cereals and rice
Waste prevention is the top priority of the European waste management strategy. In fact, as indicated in the latest Waste Framework Directive, the best option to deal with waste is not to generate it at all. In this framework, the distribution of loose dry food products through self‐dispensing systems (so‐called “loose distribution”) is being considered worldwide as a practice to reduce ...
