An environmental assessment of six scenarios for handling of garden waste in the Municipality of Aarhus (Denmark) was performed from a life cycle perspective by means of the LCA-model EASEWASTE. In the first (baseline) scenario, the current garden waste management system based on windrow composting was assessed, while in the other five scenarios alternative solutions including incineration and ...

All aluminium smelter plants discharges high volume extremely toxic electrolytic cell waste known as spent pot liner. Over the years scientists have improvised various methods for disposing these toxic wastes either by diluting with inert material or recovering its carbon value after decontaminating the toxic waste. Present paper outlines conceptual design of a commercial treatment plant which ...

Very quickly following the first international toxic waste trade scandals that took place in the late 1980s and early 1990s, the environmentally friendly word “ recycling” began to increasingly be used by waste traders to justify the export of hazardous wastes from rich to poorer countries. Today, this rationalization for toxic waste trade for industrial wastes continues. Virtually all existing...

This study aims to contribute to environmental justice research by examining how Native Hawaiians and Pacific Islanders (NHPIs), a relatively small minority group, are disproportionately impacted by environmental toxins. Proximity to three different environmental hazards is considered: toxic waste, industrial air pollution, and freeways. 2010 U.S. Census, Superfund, Toxic Release Inventory, and...

Contamination of soils, water, and sediments by radionuclides and toxic metals from uranium mill tailings, nuclear fuel manufacturing and nuclear weapons production is a major concern. Studies of the mechanisms of biotransformation of uranium and toxic metals under various microbial process conditions has resulted in the development of two treatment processes: (i) stabilization of uranium and t...
