Compliance with the RMP Rule at a Waste Management Facility
A waste management facility typically treats, stores, and disposes chemical wastes that contain chemicals listed under 40 CFR §68.130. After a thorough evaluation of the existing chemical inventories, it is determined that this facility is not subject to the Risk Management Program rule based on the exemptions given in the rule for the de minimis threshold quantities. Due to the uncertainties of ...

Magnets: A viable alternative to flotation for sand producers
Introduction The basic rudiments of mineral beneficiation have not changed for many years. The techniques have been improved, but are still essentially the same, using either a materials weight, density, shape or magnetic susceptibility to enable separation. For removing impurities from non-metallic minerals, such as silica sand, typical methods include Flotation, Gravity and Magnetic separation. ...

Environment and resolutions to avoid discontinuity in supply chain management
Supply chain management (SCM) is a quintessential area that entails numerous external factors that are both controllable and uncontrollable. Nature is indeed one of the most influential disruptor that affects a steady supply chain. The US Government has implemented many environmental laws and regulations to protect today's environment from pollutants caused by the general public, governmental ...

The environmental pyramid: a new way to deal with solid toxic waste
Our society produces large volumes of solid waste, including toxic chemical waste. For toxic solids, the current disposal practice is to dump them into isolated, lined pits, and cover them with a water-impermeable layer with a soil layer on top. Such waste deposits require 'eternal' control and monitoring, because they eventually do leak, contaminating the surrounding soil and groundwater. Here, ...

Conventional and Alternative Technologies for the Treatment of Infectious Waste
Abstract The limited scientific information about infectious waste, and the heightened public awareness of this special component of the waste stream, have contributed to the implementation or strengthening of the regulations in this area. This paper proposes a general working definition of infectious waste, and describes the systems used to limit its potential occupational and public health ...

Pollution prevention: progress towards sustainable development?
Emphasis in recent years on pollution prevention (P2) is being driven both by the limits to what can be achieved by traditional "end-of-pipe" pollution control methods and by the rise in attention to the concept of sustainable development. P2 strategies have been employed to realise reductions in toxic chemical use, waste, accidental release, and worker exposure, which can ...

Toxicity management: it's a bug's life
Untitled Document Most biological treatment plants that accept industrial wastewaters expirience problems from time to time with nitrification. Tis can result in failure of the treated effluent to meet ammonia discharge consent levels, and can lead to substantial fines. The cause of the problem can usually be traced to toxic chemicals in the incoming waste stream. Nitrifying ...
