Waste-to-Energy is a challenging management in developing countries. There are many different technologies to generate electricity or heat from wastes. However, reuse and recycling are first prioritized as left a fraction of waste can be used as energy recovery. The initial cost to generate electricity from solid waste incineration is prohibitively high due to its cost of advance technology and...

This paper starts from the premise that radioactive material, generated as a by-product of the British nuclear industry, already exists in significant quantity. The question of what should be done with this material therefore needs to be answered, even if no more of it is created. Whether the industry should continue producing radioactive waste is a legitimate question, and one which raises sig...

To assess the viability of discarded and buried vaccine strains, we examined vaccines that had been buried for >20 years in an industrial waste dump in the city of Milan, Italy. Viability results showed potential biological risk associated with uncontrolled burial of pharmaceutical industry waste, including some live vaccines.

Need for an online hazardous waste tracking system Suneel Pandey Hazardous waste management is one of the most challenging aspects of any environmental management system for any industry. There are more than 50 000 chemical substances, with one million combinations, used in industrial activities. Hazardous wastes – in the form of solids, liquids gases or sludge – are generated by a wide range o...

This paper describes the present situation of waste and by-products utilization in cement manufacturing in Japan, introduces Ecocement which is a new cement using municipal waste incinerator ash from household activities as the primary raw material, and discusses the contribution expected of the cement industry in establishing a resource recycling-based society in this country.

The construction industry, one of the most important ones in the development of a country, generates unavoidable impacts on the environment. The social demand towards greater respect for the environment is a high and general outcry. Therefore, the construction industry needs to reduce the impact it produces. Proper waste management is not enough; we must take a further step in environmental man...

Although many outlets are available for the utilization of wood fines, economical disposal of sawdust, shavings, and waste chips remains a problem of growing concern to the wood industry. This report summarizes current uses for wood residues and provides sources of further information on available outlets, processing methods, and economic considerations. USES FOR SAWDUST, SHAVINGS, AND WASTE CHIPS

Waste policy is increasingly moving on from the 'prevention of waste' to a 'sustainable materials policy' focused agenda recognising individual wastes as a resource. In order to comparatively analyse policy developments in enhanced waste management, three case studies were selected; San Francisco's Zero Waste Program, Flanders's Sustainable Materials Management Initiative and Japan's Sound Mate...

In this study, the researchers investigated the potential use of locally available waste materials from the lime stone quarry and the granite industry as a partial replacement of cement. Quarry sites and granite industry in the eastern province of Saudi Arabia produces tons of powder wastes in the form of quarry dust (QD) and granite sludge (GS), respectively, causing serious environmental prob...

A growing demand – above all in industrialised countries – for safer foods and cleaner production processes has been observed in recent times. This has led to a drive, by the agro-alimentary industries, for waste reduction and upgrading as a strategy to reduce costs and achieve new sources of income. In fact, waste may be a source of high-added value products potentially useful as beneficial fo...
