Biomass pyrolysis with biochar returned to soil is a possible strategy for climate change mitigation and reducing fossil fuel consumption. Pyrolysis with biochar applied to soils results in four coproducts: long-term carbon (C) sequestration from stable C in the biochar, renewable energy generation, biochar as a soil amendment, and biomass waste management. Life cycle assessment was used to est...

Large-scale production of antibiotics began in the 1940’s. Almost immediately, the use of antibiotics spread to agricultural uses. In livestock, antibiotics are used to reduce illness. However, a far more common use is to increase feed efficiency, resulting in better profits. (Coghlan, 1996 and Bonner, 1997) With the widespread use of antibiotics has come a variety of concerns. Primarily, fear ...

Nigeria is the most populous country in Africa. Located on the western part of Africa, it has a population of over 140million people. The country has had an annual increase in population growth rate of 3.2% from 1991. The rate of urban growth has also been estimated at 5.5% per annum. Nigeria is made up of 36 states, excluding the Federal Capital Territory (FCT) Abuja, with Lagos and Kano State...

This study examined chemical composition of tomato stalks and their possible feasibility in the production of particleboard. Three-layer experimental particleboards with density of 0.53, 0.63, and 0.73 g cm(-3) were manufactured from tomato stalks using certain ratios of urea formaldehyde (UF) and melamine urea formaldehyde (MUF) adhesives. Modulus of elasticity (MOE), modulus of rupture (MOR),...

Rapid urbanization and industrialization, population growth and economic growth in developing countries make management of municipal solid waste more complex comparing with developed countries. Furthermore, the conventional municipal solid waste management approach often is reductionists, not tailored to handle complexity. Therefore, the need to a comprehensive and multi-disciplinary approach r...

The present investigation is a case study of Lucknow, the main metropolis in Northern India, which succumbs to a major problem of municipal solid waste and its management. A qualitative investigation using strengths, weaknesses, opportunities and threats analysis (SWOT) has been successfully implemented through this community participation study. This qualitative investigation emphasizes the li...

The paper attempts a synthesis of problems relating to municipal waste management in Nigeria and proposes a conceptual knowledge management approach for tackling municipal waste problems in cities across Nigeria. The application of knowledge management approach and strategy is crucial for inculcating a change of attitude towards improving the management of waste. The paper is a review of existi...

Materials and Methods The poultry industry in India has undergone a paradigm shift, from backyard venture before the 1960s to vibrant intensive agribusiness, growing at around 8 to 10% annually over the last decade. This fast growing industry is currently facing issues regarding waste management. Accumulation of large amount of wastes is one of the major problems, posing serious challenge to th...

The Idaho National Engineering and Environmental Laboratory (INEEL) is an 890 square mile multiprogram Department of Energy (DOE) laboratory in southeastern Idaho. Over the past 50 years, the laboratory has witnessed many significant scientific advances, particularly in the areas of nuclear propulsion, nuclear reactor safety and design, and waste management.
