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...

introduction: organic fertilizers are beneficial to maintain and improve structure of the soil nutrients; however, in case of presence of pathogenic microbial agents and pathogens inside them, it will result in health problems and disease transmission. therefore, present study aimed to determine microbial quality of produced vermicomposts in yazd city. methods: this study was a descriptive-anal...

This paper seeks to examine the provisions for extended producer responsibility (EPR) within the Malaysian environmental and waste management policies and to determine its existing practice and future prospects in Malaysia. Malaysian waste generation has been increasing drastically where solid waste generation was estimated to increase from about 9.0 million tonnes in 2000 to about 10.9 million...

Waste management is the collection, transport or disposal and management of waste materials. Most waste management activities are decided upon and carried out in a public, semi-public area typically involving the waste management organization, one or more regulators and other stakeholders and members of the public. The management of waste is not only the responsibility of governments, but also ...

background: successful waste management programs are linked to internal factors, sw (strength and weakness points), and external factors, ot (opportunities and threats), and at the macro level are grounds for sustainable development. studies may be related to david’s study which presented a method to quantify strength, weakness, opportunity, threats (swot) analysis. methods: in this study, desi...

The electronic industry is the world’s largest and fastest growing manufacturing industry in the world. Discarded electronic and electrical equipment with all of their peripherals at the end of life is termed ewaste. The quantity of c-waste generated in developed countries equals 1% of total solid waste on an average and is expected to grow to 2% by 2011 and is one of the fastest growing waste ...

Fast urbanization and serpentine uses of electronic gadgets during the last two decades has led to genesis of a whopper character of electronic wastes resulting in soil, water and environmental pollutions. Thus pollution administer along with environmental safety has become the greatest worry of environmental scientists and activists worldwide. Dumping of electronic wastes, lone of the by-produ...
