Filter cake is one of the main waste products of zinc processing industries and it contains a high amount of toxic heavy metals. In this research in order to reduce heavy metals leachability in filter cake, Portland cement, natural pozzolan, diammonium phosphate (DAP), triple superphosphate (TSP), lime, zinc oxide and ground granulated blast furnace slag (GGBFS) have been used. This research’s ...

Increase in energy demand, stringent emission norms and depletion of oil resources have led the researchers to find alternative fuels for internal combustion engines. On the other hand, waste oils pose a very serious environment challenge because of their disposal problems all over the world. In this context, waste oils are currently receiving renewed interest. The properties of the oil derived...

The United States biomedical R&D community faces limited treatment and disposal options for many of the mixed wastes generated by their research activities. These options are particularly limited for tritiated mixed waste that has both moderate to high tritium content and contains RCRA-regulated hazardous components. Lawrence Berkeley National Laboratory (Berkeley Lab or LBNL) believes it is es...

There are more than half million tons of serpentine waste produced per year during mining operation in Taiwan. This study is to develop a process to manufacture fire-resistant geopolymer based on serpentine waste. The experiment results show that the waste serpentine-based geopolymer have very good physical/mechanical characteristics. For fire resistance tests, a 10 mm thick geopolymer panel wa...

Along with the rapid development of electronic products, there is a large amount of electronic waste, such as hundreds of millions of mobile phones and junk personal computers, which is not only a waste, but also a tremendous damage to the environment. The article presents a technique of reusing the electronic waste for the smart home monitoring system. It also describes how to set up the proto...

Currently, use and disposal of plastic by consumers through waste management activities in Ghana not only creates environmental problems, but also reinforces the notion of a wasteful society. The magnitude of this problem has led to increasing pressure from the public for efficient and practical measures to solve the waste problem. This paper analyses the impact of plastic use and disposal in G...

This study reviews waste water characterization of iron and steel industry and treatment procedures involved in these industries. The production of iron from its ores involves powerful reduction reaction in blast furnaces. Cooling waters are inevitably contaminated with products especially ammonia and cyanide. Production of coke from coal in coking plants also requires water cooling and the use...

One of the top strategic objectives and research areas in Europe is recovering wood from processing and end of life products. However, there are still several ‘contaminated’ wood products that are not or only partly reused/recycled. Particle board waste which is contaminated with aminoplasts is one of these products. In addition, a considerable amount of aminoplast waste resinis produced for th...

Background and Objectives: Hospitals usually generate large amounts of hazardous waste. If not managed properly, hospital waste can pose threats to public safety and damage the environment. Waste minimization is a waste management approach that focuses on reducing the amount and toxicity of hazardous wastes. This study pursues a two-fold purpose: 1) to gain insight into hospital waste minimizat...

Efficient waste paper recycling has a significant role in the sustainable environment. Recyclable waste paper as a fundamental ingredient of municipal solid wastes (MSWs) is indeed an ‘‘urban ore’’. Waste papers are considered as the solid recovered fuel which is recovered from MSW. Recyclable waste papers are segregated into various grades to produce high-quality products. Moreover, sorted pap...
