If you've been considering a research degree for some time, you probably already have an area of interest. You will be exploring your research topic for a considerable amount of time so it's important to invest time and effort in choosing the right topic. Explore your The environmental challenges from coal mining include coal mine accidents, land subsidence, damage to the water environment, mining waste disposal and air pollution. These are either environmental pollution or landscape change. A conceptual framework for

Waste Storage 'In Perpetuity'

This issue has been a major topic of discussion in the planning and permitting of new large mines such as the proposed Donlin Creek Mine and Pebble Mine in Alaska. Another mining-related issue is the perpetual storage of arsenic, which can contaminate groundwater supplies.

When mine tailings are removed from the ground in the mining process and exposed to the atmosphere and to rain water, they can react to form new minerals that trap CO2 from the atmosphere. The research highlights the potential for improving carbon capture one to two meters beneath the surface of mining wastes, where most sequestration usually occurs.

The radioactive components of mixed wastes are regulated under the Atomic Energy Act by the Nuclear Regulatory Commission for commercial sources, and by the Department of Energy for military sources. The hazardous components, however, are subject to regulation by the Environmental Protection Agency according to an environmental law known as the Resource Conservation and Recovery Act (RCRA).

SBIR/STTR technical topic areas for both the Fiscal Year 2016 (topics 10 b and c) and Fiscal Year 2017 (topics 14 a and b) included aspects of waste to energy. WORKSHOPS BETO regularly hosts workshops and listening days to enhance its portfolio and engage key stakeholders in discussion.

ASTM's waste management standards provide the guides, practices, and test methods pertinent to the process of handling residential, commercial, and industrial wastes. This process involves the collection, transport, processing, and recycling or disposal (whichever is applicable) of waste materials for health, environmental, and/or aesthetic purposes.

Open-pit mining, also known as open-cast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the

Types of Solid Waste Disposal and Management

Solid wastes sanitary landfills process is simple, clean and effective. In this procedure, layers are compressed with some mechanical equipment and covered with earth, leveled, and compacted. A deep trench of 3 to 5 m is excavated and micro-organisms act on the organic matter and degrade them.

2019/3/1Electronic wastes- Unrepairable computers and other electronic goods are known as electronic wastes (e-wastes). E-wastes are buried in landfills or incinerated. Over half of the e-wastes generated in the developed world are exported to developing countries, mainly to China, India and Pakistan, where metals like copper, iron, silicon, nickel and gold are recovered during recycling process.
