Acero argues that regulating the soderperu practices of transnational bauxite, alumina, and aluminum producers, either locally or in their home countries, is a necessary but not sufficient condition for effectively implementing sound environmental policy at the operational level. Technology hardware is only one part of the equation.

This is unlikely to occur unless pollution-prevention regulations are underpinned by technology policies and financial incentives aimed at encouraging the least-efficient firms to develop caatlogo technological and managerial capabilities to innovate. The other problem is that this strategy threatens the environmental part of that equation by pressuring firms to move into the close-down, cleanup quadrant of the corporate environmental trajectory C in Figure 2.

Air Pollution Control

With more than 20 years of systematic efforts to protect the environment and improve the quality of life for its citizens, the United States can offer several lessons to Chile and other countries with less experience. A combination of political, economic, and environmental elements has given rise to the polluter-pays principle, which in essence requires polluting companies to internalize the external costs of environmental damage caused by their production of goods and services.

Moreover, if regulations are incremental, they may promote technical change that is also incremental, involving the addition of numerous new controls at greater cost and with more overall degradation than if a new, more radical change had been introduced in the first place see Kemp and Soete ; Freeman Training for regulators, including industrial experience as environmental engineers and corporate strategists, is thus an important part of the pollution-prevention approach.

Consequently, the innovative capacity of recipients is undeveloped and they remain purchasers and operators of imported plants and equipment. Controlling pollution problems in many of these cases requires costly add-on solutions: She concludes that, particularly in a developing country, cost-effective policies are crucial and that site-specificity should be examined to ensure that regulations are relevant to the site-specific pollution hazards.


Agenda 21, one of the main outputs of UNCED, proposes two programs of relevance Skea that can be expected to lead to greater industry involvement. For the time being, however, what is needed is analytically sound documentation of the extent and the effects of recent changes in cataligo business environment, as reflected in corporate behaviour and government policy. Catzlogo efficiencies in Japanese plants have translated into both cheaper and better-value products, leading to the rapid growth and supremacy in Western markets of Japanese firms like Toyota, Nissan, Honda, and Mitsubishi.

After a long period of conservative and incremental technical change, firms are developing alternative processes for mineral production that are more economical and less environmentally hazardous. The argument rests on the assumption that the socially optimal use of an environmental resource occurs when the additional benefits in terms of goods and services it derives by permitting one more unit of pollution equal the additional costs it catlaogo.

True, mining always involves disruption of the environment, either at the surface with open-pit mines or underground with deep mines, and in most cases the mineral being sought makes up only a small part of the material that must be moved, with the result that vast quantities of waste must be handled.

Second, the most efficient firms are generally better environmental managers because they are innovators.

The policy challenge is therefore to promote environmental innovation. The term is not intended literally; indeed, a more accurate term would be cleaner technology. For example, combined regulatory and market pressures may prompt mine closure in advance of expected ore depletion. The dual aim of the project is to set a new emissions standard for smelters worldwide and to improve cost efficiencies in the processing of its ore.

Of course, there remain as many cases where the old conditions persist, and it is equally of interest to learn where and why this new business environment has not appeared. The threshold of environmental competitiveness for a given regulatory context is also X catxlogo, and company operations in compliance have environmental trajectories in the quadrants below the horizontal axis.


EPA policy documents on pollution prevention fail to emphasize training. The policy of requiring firms to reduce pollution at source, which necessarily involves changing their production technology and organization, overlooks the possibility that firms might already be searching for new ways to improve metal recovery, reagent use, energy efficiency, water conservation, and so on as part of their corporate strategies xatalogo increase competitiveness.

Of equal importance is organizational change. The research will make an original contribution by evaluating the potential of technology transfer and training particularly if governed by joint-venture agreements and are linked to credit conditionality to accelerate the development and diffusion of improved environmental-management practices.

Secondary principles are reduce waste, minimize space, eliminate inventories, and integrate quality control into the production process. Moreover, governments, organizations, or firms will have more power to negotiate the objectives and scope of the programs if they have helped finance them.

This was shown to have the double advantage of extracting extra copper and avoiding government charges for water treatment. As the MERN members develop research capability and define new areas of work and as demands on MERN’s central resources increase, new funding is being sought. An online auction of various mining machinery from Exxaro Grootegeluk and The network produces a bulletin twice annually, and this contains progress reports from each group, policy updates, industry news, professional articles, and a conference calendar.

The liberalization of investment regimes worldwide, combined with growing environmental regulation and catapogo frequent requirements for siderleru environmental-impact analysis as a precondition for sidepreru, means that objective and well-documented policy analyses are urgently needed to support decision-making in industry, donor agencies, government, and nongovernmental organizations.

MERN is an international collaborative research program involving centres of excellence in the major minerals-producing countries of the world.

The question of economies of scale in metals production further constrains the choice of technology for minimizing waste and maximizing metals recovery.
