Connecticut Resources Recovery Authority is a quasi-public agency that provides single-stream recycling and trash disposal for Connecticut cities and towns. It owns a trash-to-energy plant in Hartford, oversees another in Preston, and financed the development of others in Bridgeport and Wallingford. ==Recycled resources== The CRRA recovery facilities recycle post-consumer waste in a mixed solid waste stream, sorting by manual and mechanical methods to prepare the resources for the end user. Recycled resources generate revenues, but they also save energy. How much depends on the material: some materials such as aluminum, carpet, and copper consume so much energy in production, that recycling these energy-intensive products results in large energy savings. For example, a 2005 report by the Environmental Protection Agency estimates that one ton of aluminum can recycling saves 209 million BTUs, which is equivalent to of oil. The same report provides statistics for other materials: carpeting—106 million Btu ( of crude oil); copper wire—83.1 million Btu (14 barrels); high-density polyethylene milk jugs—51.4 million Btu (8.9 barrels); steel cans—20.5 million Btu (3.5 barrels); newspaper—16.9 million Btu (2.9 barrels); and glass—2.7 million Btu (0.47 barrels) Recycling also preserves natural resources. About 20 trees are needed to produce one ton of virgin paper and on average Americans use about 730 pounds of paper (approximately a third of a ton) per year.〔 Recycling everything is not possible. When it comes to disposal of the remaining waste, environmentalists favor sending it to trash-to-energy plant rather than a landfill where it can pollute the soil, water, and air through contamination and excess methane production.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Connecticut Resources Recovery Authority」の詳細全文を読む スポンサード リンク
