The incinerators described were developed to dispose of waste liquids and sludges fr' om paint and resin plants. The operation of two prototype designs demonstrated: (1) complete combustion without fluid atomization, (2) ability to burn organic liquids containing dissolved and suspended solids, (3) low noise level, (4) smoke-free stack effluent without the use of air pollution control equipment...

Composting is a biological decomposition process where microorganisms convert raw organic materials into relatively stable humus-like material. During decomposition, microorganisms assimilate complex organic substances and release inorganic nutrients. An adequate composting process kills pathogens and stabilizes compost organic carbon before the material is land-applied. In 1997, 27.2 million m...

We develop an associative synthesis of metal–organic materials that combines solid-state metal oxidation and coordination-driven self-assembly into a one-step, waste-free transformation. The methodology hinges on the unique reactivity of ortho-quinones, which we introduce as versatile oxidants for mechanochemical synthesis. Our strategy opens a previously unexplored route to paramagnetic metal–...

This study was conducted to evaluate the impact of municipal waste compost and manure on soil chemical and physical properties quality and crop production in Sari city (north of Iran). In this study, the effect of compost and manure (cow and sheep) on the quality of soil organic material with experimental measurements was investigated. An experiment was conducted in a completely randomized desi...

long-term application of fertilizers containing p, especially organic fertilizers, usually increases the water soluble and available p of soil and at the same time may result in p accumulation in soil. organic fertilizers may also increase movement of p in the soil profile that could result in surface and ground water pollution. an experiment was conducted on field plots that received three app...

The paper summarises a literature review into waste management practices across Africa as part of a study to assess methods to reduce carbon emissions. Research shows that the average organic content for urban Municipal Solid Waste in Africa is around 56% and its degradation is a major contributor to greenhouse gas emissions. The paper concludes that the most practical and economic way to manag...

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 ...

BNFL owns and operates the UK’s principal solid Low Level Radioactive Waste disposal site at Drigg in Cumbria, north west England. Drigg has been receiving waste since 1959 with approximately 900,000 m 3 of waste disposed of to date. Waste accepted for disposal at Drigg comes in a variety of forms including rubble, spoil, redundant equipment, scrap and process waste, and typically contains sign...

The biochemical methane potential (BMP) of raw poultry litter waste was assessed in batch assays. Biological co-treatment with Clostridium cellulolyticum, Caldicellulosiruptor saccharolyticum and Clostridium thermocellum as bioaugmentation strains, and thermochemical pre-treatments with lime and sodium hydroxide performed at different temperatures and pressures were applied as strategies to imp...

Organic compounds contained in radioactive waste can be classified into different categories. The ability of organic compounds to form stable complexes with metallic cations is widely recognized. The effect of Low Molecular Weight (LMW) organic compounds present in the wastes, or produced via their degradation on the mobilization of radionuclides under repository conditions must be assessed. Fo...
