Biotreatment of oil refinery sludge

Utilization of waste materials generated in different industries is important from the points of ecology, economics and conservation of non-renewable resources. One of the main waste materials in petroleum industry is oil sludge, which is produced by the treatment of wastewater, from various refining and tank cleaning processes. Biotreatment or otherwise biodegradation by natural populations of microorganisms is one of the primary mechanisms by which petroleum and other hydrocarbon pollutants can be eliminated from the environment.

Process design and economic evaluation for the recycling of exhaust sands from a magnesium foundry plant
© Aristotle University of Thessaloniki (6/2009)
A magnesium and aluminum foundry plant located in Northern Italy generates every year about 1200 t of exhaust sands coming out of the magnesium casts production process. This foundry waste cannot be treated by means of the usual thermal regeneration process owing to the presence of potassium fluoborate, a salt which becomes plastic at high temperature values and binds silica grains in close heaps.

New automated technologies in environmentally sensitive shipyards

Shipbuilding industry is known as one of the hardest metal industry with several chemicals and hazardous material. Most of the production processes such as welding, painting, blasting and fiberglass production have direct impact on workers health. There are several wastes and pollutants being released during shipbuilding and ship repairing processes.

The challenges of implementing on-site composting in an industrial manufacturing business

Although the road to successfully implementing on-site composting in an industrial manufacturing business and realising its zero-waste policy has been much longer and much rockier than anticipated, and we are by no means at the end of this road, it was and still is the best available option for GELITA Australia to deal with its organic by-products and ensure they are used beneficially.

Influence of Cr inhibitor on the H2S formation and biogas production volume using industrial sludge waste source with sulphur reduction bacteria addition

Industrial sludge waste disposal receives increasing attention and the Indonesian legislation concerning the discharge of industrial sludge waste as landfill is very strict.

Hazardous (prescribed) waste repository – siting and design to meet sustainable development criteria
© IWWG International Waste Working Group (10/2007)
The State of Victoria in Australia has recently unsuccessfully sought approval for a long term containment facility (LTCF) to provide for the management of those industrial wastes which are perceived to represent a high risk to public health and the environment. This is the fourth such proposal for the State in 25 years, all previous attempts have also failed. The basis for the facility development and design were criteria developed by a committee representative of the community and industry and policy developed by the regulator which reflected community perceptions.

Optimization of coagulation and flocculation processes for pretreatment of industrial landfill leachate

A study was conducted to evaluate the possibility of physico-chemical treatment of industrial landfill leachate. The investigated leachate has been formed at the industrial landfill, where non-hazardous wastes from all phases of tanning processes including wastewater treatment are disposed.

In several developing countries, the poor management of hazardous waste is related to insufficient regulations, inability to enforce them, or weak institutional structure (Tarras- Wahlberga, 2007; Santhakumar, 2003). Weak, soft or uneven enforcement of environmental law discourage industries from reducing pollution (Vermeer, 1998; El-Zayat, Ibraheem et al., 2006). Environmental laws differ among various countries. Generally speaking, developing countries have less stringent laws than those in developed countries (Kamau, 2005).

Until recently, there was no facility in Mozambique for the safe disposal of hazardous waste. In 1999 the Ministry for Environmental Co-ordination (MICOA) of the Government of Mozambique commissioned various studies to investigate and quantify the problem of hazardous waste generation in Mozambique. These studies used empirical methods based on population figures, gross domestic product and numbers of chemical industries versus other industries. However, the hazardous waste figures produced were unreasonably high and in 2001 MICOA commissioned a waste survey regarding all potential hazardous waste producing industries in southern Mozambique.
