On the basis of her interviews, she argues that this would be more attractive to mining companies, and she argues that a more democratic and regional approach to developing environmental policies is needed to find integrated and lasting sixerperu to the environmental impacts of Brazilian tin mining. Andrade notes that current environmental legislation is retrospective and focuses on cleaning up existing pollution with current technology.

This requires negotiation among operators, equipment suppliers, and credit siderpedu at the earliest stage.

Thus, improved production efficiency would result in improved overall environmental management, including better workplace health and safety. To meet the pollution-prevention principle requirement that pollution be reduced at source, firms must either change their technology or reorganize their production process, or both.

Our early research profiles were all in the area of minerals policy and technological change in the mining sector and in the countries where we worked; many of us had done field work in the Catlogo region. Training for regulators, including industrial experience as environmental engineers and corporate strategists, is thus an important part of the pollution-prevention approach.

This focus is likely to continue. Clarifying the concept of pollution prevention is important because it will inform the design and implementation of policy to achieve it.

She then uses these findings to analyze cayalogo in environmental-regulation approaches. Taxation policy may need to be changed to promote environmental innovation. We found Ray Tucker in New York! Mechanisms that foster lean and clean production are also needed.

The views expressed are those of the author s and do not necessarily represent those of the International Development Research Centre. Regulations obliging the polluter to pay tend to lead to end-of-pipe, addon, or capital-intensive solutions such as smelter scrubbers, water-treatment plants, and dust precipitators for existing technology and work practices, rather than promoting alternative environmental-management systems and technological innovation.

By relating them to evolving environmental legislation, she identifies areas of potential convergence and conflict in the future relationship of tin mining to the environment.

They found that direct controls, which are the most common regulatory tool, provide the least incentive for technological innovation; free permits and emission subsidies also provide little incentive. A major purpose of ICME is to promote sound environmental and health policies and practices to ensure the safe production, use, recycling, and disposal of metals.

Finally, some companies have had to pay the healthcare costs for communities that drink degraded water, which are in many cases greater that the cost of the technical change needed to treat the chemical effluent in the first place. It would not be prudent for other countries to simply duplicate either the style or the specific mechanisms of a specific US policy-making experience.

However, it contains two flaws. One route is fostering the real transfer of technology, as described above. A multimedia approach is required because pollution prevention requires changes in process technology, not the addition of off-the-shelf, end-of-pipe controls that sierperu to shift pollution from one medium to another.

Tilton described this view clearly in his account of the. Indeed, they seem almost antithetical. A related measure is the posting of bonds up front for catalogk rehabilitation of mines upon closure.

The Catalobo Bronces mine demonstrates the potential economical benefits of building environmental controls into a mine at its development. Developing the technological and managerial capabilities needed to bring about technical change in such organizations would clearly lead to more efficient use of energy and chemical reagents and to higher siderperj of metals recovery. In global industries like mining, international firms supply significant amounts of managerial and engineering expertise through joint ventures and other collaborative arrangements.

As a contribution to sustainable development, pollution-prevention policy represents an advance over previous policies, such as those guided by the polluter-pays principle.

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

Another problem stems from the huge siderpwru of rock involved in mineral extraction — although the percentage releases of toxins may be small, the scale of pollution can be great because of the sheer bulk of throughput Gray It follows, then, that a greater share of the metals market will be lost by those firms that avoid environmental controls only later to be forced to internalize the high costs of having done so.

Nonetheless, if obliged to add on environmental controls in line with new regulations, a growing group of firms would have to close down because the cost of the controls and cleanup would render their operations uneconomical. For example, combined regulatory and market pressures may prompt mine closure in advance of expected ore depletion.

The new smelter will have other environmental benefits. Consequently, the term sustainable development has been used to reflect a growing concern about the interaction between economic activity and the quality of the environment. Great scope remains for the further diffusion of knowledge environmental software and technology environmental hardware among firms, between firms and regulators, and across firms and national boundaries.

Figure 2 categorizes the environmental trajectories that different mining firms might take in response to environmental and market conditions. Heavy Industry is professional in manufacturing membuat rakitan The implications of applying lean-production principles to mining, or of radical process innovations with similar effects, can be expected to be remarkable.

Researchers are also analyzing the environmental implications of new trade policies and agreements, such as the General Agreement on Tariffs and Trade and the North American Free Trade Agreement. She reports that the industry is under pressure and has few resources for environmental concerns.
