By the time 1978 is over, the Washington metropolitan area will have cast off about 1.7 million tons of paper, plastic, garbage, cans, bottles and other residential, commercial and industrial solid waste.

That estimate, provided by Trevis Markle, an environmental planner at the Washington Metropolitan Council of Governments, doesn't include constrution rubble or heavy, non-incinerable solid waste.

While most of the area's trash is destined to end up in costly and limited landfills, some of it will be recycled. There has been a "tremendous increase" in recycling efforts around the country since 1970, according to Neil Seldman, director of waste utilization at the Institute for Local Self-Reliance.

Although most of the estimated 3,000 drop-off recycling centres that sprang up in the United States from 1970 to 1973 have now disappeared, Seldman said, they are being replaced by pick-up services for recyclable goods.

Usually, recyclable materials are delivered directly mills or plants or are sold to middlemen. When the materials are sold to middlemen. When the materials are sold to middlemen, the paper is shredded and bailed and metal is shredded and compacted. The items are then sold to manufacturers.

Manufacturers sometimes make new products from recycle materials are mixed with virgin materials . The materials don't always come back in their original form. While newspapers can be recycled as newsprint, they also canreturn as celulose insulation orother products. Glass can be used for many different products, such as bottles, pipe, cement, or road construction materials. Some rubber tires can be retreaded, and other tires are mixed with asphalt for roads.

Manufacturers want recycled materials, Seldman said, because "it's cheaper to use secondary materials than virgin materials." Producing aluminum products from recycled aluminum takes 5 percent of the energy it would take if new materials were used, Seldman said. In making paper products from recycled paper, 30 percent of the energy is saved; in steel, 74 percent of the energy is saved; in steel, 74 percent of the energy is saved, and in glass, the savings is about 25 percent, he said.

The following guide to some recycling facilities in the area shows what the District and some organizations are doing to recycle some of the area's solid waste. The guide includes information on how to go about getting rid of bulky houshold items such as refigerators, stoves and furniture.

In the past the District ran a newspaper recycling program, but "it cost us more to pick (newsprint) up than it did to recycle it," according to Herbert L. Tucker, the city environmental services director.

An in-house committee is working on a total solid waste study, Tucker said, which may include a four or five-year plan and include recycling. It is not known when the study will be completed, he said.

"We have many citizens who are interested" in getting recycling programs going in the District, Tucker said, but "I'm just not sure that I'm prepared to ask the citizens" to separate glass by color, separate newsprint and go to any additional trouble in putting out their refuse until a system of recycling is developed "that will bear fruit," and be financially as well as ecologically sound.

District officials are meeting with the National Black Veterans Organization about the possibility of setting up a demonstration waste collection program in the city. "I'm going to lean over backwards in working with them," Tucker said. "If we can work out some way where they can take (waste paper, bottles and cans) off our hands" for a reasonable amount of money, I'll be interested. No specific recommendations for the project have yet been made.

The city will pick up bulky house-hold appliances such as stoves, refrigerators, water heaters or washing machines from homes with three or fewer family units. To request a special pick-up, call 399-4600, and you will be told when to put the items out.
