Waste treatment facilities are often shared among different municipalities as a means of managing wastes more efficiently. Usually, management costs are assigned to each municipality depending on the size of the population or total amount of waste produced, regardless of important environmental aspects such as per capita waste generation or achievements in composting or recycling. This paper pr...
Original scientific paper Recycling of all materials should be supported by modern society. Material recycling is one of the most important ways of dealing with waste. One of material recycling possibilities is an inclusion of waste into primary matrices. A suitable ratio and a combination of waste particles influence in a positive way mechanical properties of the material in which they are dis...
The Packaging and Packaging Waste Directive has had an undeniable impact on waste management throughout the European Union. Whereas recycling and recovery targets are the same, member states still enjoy a considerable degree of freedom with respect to the practical organization and management strategies adopted. Nevertheless, in all cases, the industry (which brings packaging material onto the ...
This paper considers a truck scheduling problem in the context of solid waste collection in Porto Alegre, Brazil. The problem consists of designing ``good" daily truck schedules over a set of previously defined collection trips, on which the trucks collect the solid waste in fixed routes and empty the loads in one of the several operational recycling facilities in the system. The main objective...
This study assessed the knowledge, attitudes and practices on food waste of selected households in the northern province of the Philippines. The results of the assessment were used as bases for formulation of a recycling system. A total of one hundred rural households were selected using stratified equal allocation sampling technique. Data were collected through the use of researcher-made quest...
Recent years have seen increased attention paid by geographers to the phenomenon of household waste recycling. Much of this attention by geographers has focused on contemporary recycling, especially contemporary policy and behaviour. This article takes a wider temporal perspective and considers the antecedent ‘National Salvage Campaign’ of the Second World War. It considers the conceptual lesso...
EU and UK Government targets for minimising and recycling household waste has led the responsible authorities to research the alternatives to landfill. In the work reported here the local waste collection authority (Charnwood Borough Council) has adopted the aspirational strategy of becoming a “Zero Waste Borough” to lead the drive for public participation. The work concludes that the separate ...
Electronic waste (e-waste) has emerged as a new policy priority around the world. Motivations to address e-waste include rapidly growing waste streams, concern over the environmental fate of heavy metals and other substances in e-waste, and impacts of informal recycling in developing countries. Policy responses to global e-waste focus on banning international trade in end-of-life electronics, t...
Towards an efficient utilisation of resources, waste minimisation and reuse through recycling and energy recovery is becoming as important as energy efficiency. Knowledge of municipal solid waste flow provides the starting point for evaluating management efficiency measures implemented. This study aims at applying material flow analysis towards evaluating the existing waste management approach ...
Currently there are no established or proven recycling options for an estimated 100,000 tonnes of wool-rich carpet shred waste produced annually in the UK. The aim of this essay is to review existing knowledge and to identify areas of future research required to identify practicable recycling options. A study of the literature on the possible uses for wool waste identified three main avenues of...
