The Plasma Processing of Steel Plant Wastes
ABSTRACT: Electric arc furnace (EAF) dusts, have been successfully treated in plasma-fired carbothermic reduction furnaces to recover metal values. Although the technology is equally applicable across the range from plain carbon to stainless steels, historically, it is the latter that has been the more commercially successful. Because the plasma heat source is independent of process chemistry, ...

Recycling and Waste World - Turning difficult waste into a useful resource
Swindon-based Tetronics specialises in a thermal processing system that treats hazardous waste at source. Geraldine Faulkner talks to CEO, Stephen Davies, to find out about the benefits the company’s plasma process can bring to waste management; especially when it comes to dealing with ‘difficult’ materials. David Cameron is not the only person who is encouraging engagement ...

Mitsubishi corporation - Spent Potliner (SPL) hazardous waste treatment - Case Study
The Challenge Spent Potliner (SPL) is generated in the primary production of aluminium and worldwide is estimated to rise at a rate of over 500,000 tonnes per year. The SPL waste contains concentrations of cyanide and fluoride and gives off noxious and flammable gases when in contact with moisture. Unless carefully handled, these contaminants readily "leach" into the surrounding soils and ...

Platinum group metal recovery from spent catalysts - Case Study
The Challenge Catalyst wastes, including automotive catalytic converters and industrial catalysts, contain Precious Metals and specifically Platinum Group Metals (PGMs), which are valuable as a result of their low natural abundance, unique properties as well as the complex and costly processes that are required for their extraction and refining from primary sources. Furuya Metal Co. Ltd., Japan ...

12 types of air emission treatment equipment
During the industrial production of products, as long as there is waste gas, environmental protection equipment must be installed. Otherwise, if the EIA fails to meet the standards, it will face fines. Serious and refusal to make corrections may also face the risk of suspension of production and business.Common 12 kinds of air emission treatment equipment1. The fume purifier is a fume exhaust gas ...

A combined process of non-thermal plasma with sludge stabilization for the simultaneous reduction of odor and organic waste
Odor emissions and sludge disposals have become most challenging issues in many sludge treatment plants, and separate chemical oxidation processes have been commonly employed for these problems. It is, therefore, necessary to develop a combined process that simultaneously reduces the odor emissions and the amount of waste sludge. In this study, a non-thermal plasma reactor using a dielectric ...

Electronic Waste: The Rich Resource in the Urban Mine
Forgetting your mobile phone can be a real pain, playing on your mind during the day. Then as you think you can feel your phone vibrating in your pocket and you come to realise how dependent we are on our gadgets. Electrical equipment has changed our lives completely and we rely on phones, microwaves, TVs, kettles, computers to keep us informed, entertained and even alive. It is hard to imagine ...

Time to address the air pollution control residue problem
The incineration of municipal solid waste is gaining increasing importance in the UK, especially as the burning of waste can be used to generate energy, providing a more sustainable solution to our waste problem by diverting it from landfill sites. An issue with incineration is that some of our waste contains hazardous chemicals such as chlorine and lead which are volatilised during the process. ...

Treatment of ship sludge oil using a plasma arc waste Destruction system (PAWDS)
The Plasma Arc Waste Destruction system (PAWDS) uses a plasma torch to quickly gasify solid waste on board ships. Developed under the support of the US Navy, this compact one deck system has been in commercial operation on board a cruise ship for more than three years. With the support of Carnival Cruise Lines and the National Research Council of Canada, the PAWDS was recently modified in order ...

Common treatment methods for industrial organic waste gas
At present, the international treatment methods for industrial organic waste gas mainly include physical method, chemical method, biological method, including adsorption, direct combustion, catalytic combustion, chemical oxidation, biological filter and other treatment methods. At this stage, my country's main treatment processes for organic waste gas include isolation method, combustion method, ...

Keeping APCr out of Landfill
The CIWM have recently featured an article by our very own Dr David Deegan in the latest edition of their magazine. The article explains why Tetronics International were unhappy to be informed recently that Defra ministers had taken the decision not to remove the derogation that allows Air Pollution Control residues to be disposed of to landfill at three times the standard waste acceptance ...
