Towards a Recycling Society

Future economic growth depends on the efficient marshalling of energy, raw materials, and scarce financial capital. If Pakistan makes the transition to a recycling society most quickly and smoothly it will have the healthiest environment and strongest economy.

An inventory of discards would reveal metal wastes more valuable than the richest ones, paper wastes representing thousands of hectares of forests, and plastics wastes incorporating highly refined petrochemicals. That these products rich in raw materials and concentrated energy are frequently considered worthless is indicative of a distorted economic system. We are literally throwing away our future.

Recycling offers the opportunity to trim waste disposal needs, and thereby reduces disposal costs, while simultaneously combating global environmental problems. Recycling metals, paper, glass, plastics, and organic wastes would lessen the demand for energy and materials.

Managing solid waste is a global problem: Refuse is produced throughout the world. But it is also a local problem in that there is no such thing as global waste stream. The cumulative waste management decisions made by local and national governments affect global energy balances, the rate at which the atmosphere warms, and the amount of pollution emitted into the environment. They also affect international trade flows and the accumulation of debt. Individuals are not powerless in the face of these problems that sometimes seem too abstract or remote for constructive action. The degree to which people and nations act together to conserve raw materials and energy resources can slow the rate at which the global ecosystem is altered.

In the growing cities of Pakistan the volume of discarded materials is surpassing the available managerial and physical capacities to dispose of them. Municipalities must watch their piling garbage piles and mounting problems. Adequate waste management infrastructure does not exist. No effort is being made to reduce waste volumes and recover recyclable materials.

Recycling programs that require not only a new way of thinking about waste but greater involvement by a host of small, dispersed participants face even greater institutional barriers. Despite these obstacles, our cities should integrate recycling into our waste management plans. These cities will thus save money by avoiding disposal costs and by selling secondary materials.

Getting consumers to participate and establishing markets for recovered materials are the keys to successful recycling programs. Several approaches have effectively increased recovery rates and sales opportunities. Consumers can segregate their recyclables for pickup, permit others to retrieve the valuable components, or pay for a central processing plant to separate them. They may also return selected items to the place of purchase or take them to a collection or redemption center.

The demand for recovered products can be enhanced by meeting the resource needs of regional industries, exploring new uses for secondary materials, and offering economic incentives to waste processors and companies that use recycled materials as product inputs. Procurement policies that either favor or explicitly do not discriminate against goods made with post-consumer wastes also boost demand. Market stimulation simultaneously requires guaranteed supplies of high quality secondary materials. Competition from virgin resources and industry standards for the finished product set the operating parameters. If recycled materials are not as reliable, they will not be used.

Programs geared to the recycling of specific products often include a monetary incentive, usually in the form of a deposit. When consumers purchase carbonated beverages or milk jugs, for example, they may be charged separately for the container. If it is returned clean and intact, the consumer receives a refund. Once popular, voluntary deposit programs will go and most schemes shall be spurred by legislation.

Retailers can also purchase reverse vending machines to accept returned containers and disburse deposit refunds. After inserting their containers (as rapidly as one per second), customers are issued either cash or a redeemable voucher, sometimes accompanied by promotional coupons. Most of the machines are designed to accept aluminum, but reverse vending machines that accept glass are already on the (Western) market.

Recycling programs are most effective when integrated within a city’s overall solid waste management plan. If added as an afterthought, and implemented outside of the waste collection system, recycling schemes typically have lower recovery rates.

To encourage the use of recycled products, government can require its purchasing agents to buy competitively priced goods that contain a certain percentage of post-consumer stock. Reports, laws, and different forms printed on recycled paper, government vehicles lubricated with refined oil, and public roads paved in part by recovered rubber all represent huge markets.

Use of recycled paper by government agencies is important not only because of the volume of government purchases (creating a large market demand), but also because government procurement arrangements will be used by province, local and private organizations as a model to establish programs of their own to buy recycled paper. Additionally, as the market grows for recycled paper, the unit cost will go down, reducing costs for all organizations.

If government is going to encourage recycling, it must also take some responsibility for enlarging secondary materials market. Government regulations and fiscal incentives may compel manufacturers to produce recyclable products and packaging.

Law should require all levels of government and government contractors to purchase “items composed of the highest percentage of recovered materials practicable, consistent with maintaining a satisfactory level of competition.”

Government can also generate markets by encouraging manufacturers to use more discards in their production processes and altering nonessential quality standards. Tax incentives to encourage the purchase of recycling equipment are an approach that will gain favor.

Less waste means less demand for expensive garbage-hauling equipment and waste transfer stations, as well as the loss of habitat for disease-spreading insects and rodents. Greater use of recyclable materials cuts the needs for imported resources, cuts the need for imported resources, reduces energy consumption, and curtails water and air pollution. Societies that recycle can more efficiently and less expensively allocate scarce energy and materials among growing populations. (www.asifjmir.com)
