W generation and resource shortages have long been recognized as two of the greatest challenges human society is facing. In the early 1970s, the Club of Rome, a group of pioneering global thinkers, predicted in their milestone book The Limits to Growth that “if the present growth trends in world population...pollution ... and resource depletion continue unchanged, the limits to growth on this p...

The recycling and separation of waste from the source could reduce the amount of unusable waste. Workers in this sector are exposed to severe health complications. The present study aimed to assess the health status of waste recycling workshops in Jouybar and Ghaemshahr, Iran in 2018. In this descriptive, cross-sectional study, data were collected using a researcher-made questionnaire, the reli...

Cities are increasingly challenged in sustaining their growing populations with food. As fossil energy reserves are depleted, the sustainability of food production is highly dependent on the ability to yield more food relative to resource use. In preparing cities for peak oil, urban food systems are therefore needed that make better use of local and renewable resources, as opposed to imported a...

One of the main issues of nanotechnology is producing materials with new properties. Nanotechnology, as a powerful tool, has the ability to create evolution in the agricultural system and food–medicinal industries across the world. Producing a high-performance material from reclaimed cellulose material will increase motivation to recycle these materials at all phases of paper production and rem...

Electronics waste is becoming a crisis for the society. Huge accumulation of e-waste and their recycling through primitive means for extraction of precious metals is real concern in the developing countries as e-waste contains hazardous materials. Recycling of e-waste through proper technologies is, however, considered to be a profitable business in developed countries due to the presence of pr...

Salty food waste is difficult to manage with previous methods such as composting, anaerobic digestion, and incineration, due to the hindrance of salt and the additional burden to handle high concentrations of organic wastewater produced when raw materials are cleaned. This study presents a possibility of recycling food waste as fuel without the burden of treatment washing with water by pyrolyzi...

The current waste management literature lacks a comprehensive LCA of the recycling of construction materials that considers both process and supply chain-related impacts as a whole. Furthermore, an optimization-based decision support framework has not been also addressed in any work, which provides a quantifiable understanding about the potential savings and implications associated with recycli...

Ecosystem is affected by uneducated, unplanned and ineffective waste management. The cycle of garbage generation and recycling is effective to make the cities environment more pollution free, clean, green and habitable for healthy living. In an effort to understand the dynamics of waste management and scope in Delhi & NCR the paper looked at the systems in place for collection and recycling of ...

Postconsumer plastics recycling constitutes a small fraction of public recycling, primarily because of the costs associated with collecting, sorting, and processing. As a result, the cost of manufacturing us. ing virgin material is often less than using recycled material. Plastic waste must be sorted to achieve the highest value recycled resin. Optical and artificial neural network technology m...
