s. The solution for reducing port-related pollution is multi-fold, encompassing attainable alternatives and long-term reduction goals. Examples of simple steps include a restriction on engine idling for ships in the port and the use of cleaner grade diesel fuels. Some more expensive measures can be taken to mitigate the pollution of ships. Replacing older model ships with ships containing new engines allows the ships to meet modern emission standards. Exhaust systems can also be retrofitted in order to reduce exhaust emissions. Looking ahead into the future, there are a few technologies being developed. For example, plugging ships into "shore-side" power sources may eliminate the need for idling engines. Additionally, various sources of alternative fuel are being developed, the most significant of which is a

(IFG) is to increase the amount of local trading, thereby reducing the number of miles that ships have to travel. Another approach regards the strategic placement of ports close to land transportation infrastructure such as roads and railroads. Again, this reduces the distance that vehicles have to travel between the initial and final destinations. Railroads that reach all the way to ports are a significant way to produce less toxic pollutants, as this eliminates the need for less-efficient trucks to transport the goods from the coastal port to the inland railroad infrastructure.

According to Singh, the groups of people most affected by air pollution include children, people suffering from an underlying chronic disease, the asthmatic, and elderly. These groups are faced with an increase in trips to the hospital, worsened cough, episodes of rhinitis, and asthma attacks. Theilman states that the Clean Air Act has done a successful job at assessing and limiting the pollutants that harm humans from stationary and mobile sources. With policies like the Clean Air Act, and replacement of trees removed by deforestation, humans can reduct their carbon footprint and improve the quality of air.


Health hazards

P2 strategies can mitigate many health hazards associated with pollution. Long-term exposure to certain pollutants can cause cancer, heart disease, asthma, birth defects, and premature death. Additionally, pollution of bodies of water can be detrimental to

In industrial processes

The possibilities of P2 strategies in industrial processes are still being implemented at the corporate level, but benefits are already being realized by many companies. The view of P2 in industrial businesses has shifted from one of necessity to one of strategic advantage. If companies invest in P2 methods early in their development, they realize greater gains not too far down the road. Additionally, if companies do not produce waste, they do not have to worry about properly disposing of it. Thus, P2 is a proactive measure taken to reduce costs in the long run that would have been dedicated to disposal and elimination of waste. There are two main ways to reduce waste through P2: increased efficiency and technology improvements. Waste reduction at the source implies the same amount of input raw materials with less waste and more output of the product. Technology improvements imply changes to the production process that reduce the amount of output waste, such as an improved

process. Companies are moving past simply complying with the minimum environmental requirements, and they are taking a more strategic, forward-thinking stance on tackling the issue. One strategy is "in-process recycling". Though it is not the most efficient form of "reduction at the source", recycling is very profitable due to its ease of process. By engaging in recycling practices, industries not only cut down on the amount of material discarded as environmentally-hazardous waste, but they also increase profitability by reducing the amount of
raw material A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials/Intermediate goods that are feedstock for future finished ...
purchased. The most widespread strategy is "reduction at the source", which is the idea that byproducts of production can be reduced through efficient and careful use of natural resources. This method reduces the amount of dangerous pollutants present in waste before the waste is released. In turn, this creates a safer environment free of hazardous waste. This idea ties strongly into the benefits to corporations of investing in newer, more efficient technology.


Strategies


P2 task force

In order to reduce costs of P2 techniques, many officials are turning to pollution elimination strategies, thereby eliminating any need for end-of-pipe solutions. A task force was created by the EPA in order to directly target reduction strategies. The P2 program task force has 5 main goals: # create feasible P2 objectives and corresponding time frames # provide training to the individuals involved in the effort # oversee the program's main tasks and measure progress # evaluate the progress of the effort # maintain the program's goals long term


Voluntary approaches

Voluntary approaches to P2 are on the rise. Governmental organization often collaborate with businesses and regulatory agencies to create a structure of guidelines. There are four types of voluntary approach programs: public voluntary programs, negotiated agreements, unilateral commitments, and private agreements. Public voluntary agreements are the least restrictive. Environmental authorities collaborate and create specific guidelines. Companies are then invited to follow these procedures on a strictly voluntary basis. Negotiated agreements are created through collaboration between public authorities and industry authorities. The agreement establishes bargains that are beneficial to the industry. Unilateral commitments are established by industry authorities alone, and the guidelines they set are self-regulated. Private agreements are established between "polluters" and other affected parties. The regulations set forth create a compromise regarding a variety of pollution regulation strategies. The United States mainly follows the end-of-pipe prevention strategy. However, US President
Richard Nixon Richard Milhous Nixon (January 9, 1913April 22, 1994) was the 37th president of the United States, serving from 1969 until Resignation of Richard Nixon, his resignation in 1974. A member of the Republican Party (United States), Republican ...
created the Environmental Protection Agency (EPA) in 1970, and one of its principal missions was to regulate pollution. EPA's implementation of policies is almost entirely voluntary. There are a few keys to a successful voluntary approach. First, the program needs a dependable source of funding (from the government, usually). The program also needs a dynamic relationship with the targeted industries. This creates a base of trust between all involved in the agreement. In terms of regulation, the program should be monitored by a reliable source. In order to assure that the program will establish itself long term, there should be visible benefits to the participants and obvious results to the greater community. The long-term establishment of the program also comes from setting attainable goals to measure progress.


Governmental approaches

EPA has published waste minimization guidelines that comprise 5 major steps: # organizing the primary task force # assessing the current pollution situation # evaluating the feasibility of different program options # reporting and planning the preparations based upon the analysis # implementing the program. This framework mainly benefits smaller facilities.


Waste reduction algorithm

The EPA makes available software that employs the Waste Reduction Algorithm. They use the acronym WAR for this method and state "the goal of WAR is to reduce environmental and related human health impacts at the design stage". The WAR tracks pollutants through the entire production process in order to obtain accurate measurements.


Industrial efforts

By maximizing P2 opportunities, some companies choose to redesign their entire industrial process. Managers focus more on what enters and moves through the entire process, instead of only focusing on the output. Overall, the P2 strategies that financially benefit companies are the most likely to be implemented. However, since P2 has only recently been realized as a benefit, many corporations have not adopted significant measures to realize the potential gain.


Potential benefits

Pollution prevention can also be viewed as a form of environmental entrepreneurship, as companies see opportunities to reduce costs of waste treatment, storage, and disposal. For example, 3M has accrued a savings of over $750 million since 1973 due to their implementation of P2 incentives. If implemented correctly, P2 strategies can result in an increase in process yield. By reducing the amount of pollution released, companies can avoid some of the liability costs accrued when large amounts of pollution are released and contaminate the land on which the facility is located.


Individual efforts

According to EPA, there are some everyday steps that can be taken to prevent pollution: * Use paper in limited quantities, and print double-sided. Also, look for paper that has been made with recycled materials. * When shopping, buy in bulk in order to reduce the amount of packaging required to package the goods. Look for products made with recycled materials. Bring reusable bags in which to carry purchased goods in order to reduce the number of disposed paper/plastic bags. * Use water sparingly by installing water-efficient shower heads and faucets, and install energy-efficient appliances. Make sure that sinks and hoses are not dripping. Do not excessively water plants. * Use transportation efficiently, and utilize mass transportation when possible. Recycling used motor oil is also a way to eliminate the disposal of a hazardous material. * Eating locally produced foods reduces the amount of fuel required for the food's transportation. Additional examples of P2 include using energy efficient machinery, developing clean-burning fuel, reducing the amount of chemicals released into water sources, creating a production process that results in a reduced amount of waste, and utilizing water conservation techniques.
