Chapter 19 Section 2: Reducing Solid Waste

Source Reduction  any change in design, manufacture, purchase, or use of materials or products to reduce their amount or toxicity before they become municipal solid waste.

Buying Less  If you buy products that  have less packaging  that last longer  that can be used more than once Then…manufacturers will produce more of those products to satisfy the demand of the consumer.

Lasting Longer  products that last longer and that are designed to be easily repaired would both save resources and reduce waste disposal problems.

Recycling  process of reusing materials or recovering valuable materials from waste or scrap  saves energy, water, and other resources

Recycling Saves Energy  95 percent less energy is needed to produce aluminum from recycled aluminum than from ore  5 percent less energy is needed to make steel from scrap than from ore  70 percent less energy is needed to make paper from recycled paper than from trees.

Composting  Yard waste often makes up more than 15 percent of a community’s solid waste  people also put fruit and vegetable trimmings and table scraps in their compost piles  The warm, moist, dark conditions inside a large pile of biodegradable material allow bacteria to grow and break down the waste rapidly

Compost  dark brown, crumbly material made from decomposed plant and animal matter that is spread on gardens and fields to enrich the soil

Some Cities Compost at Central Facilities  Good idea for food- processing plants and restaurants

Changing the Materials We Use  single-serving drink boxes are made of a combination of foil, cardboard, and plastic.  The drink boxes are hard to recycle because there is no easy way to separate the three components.

More products could be recycled if they were made of…  Recyclable glass  Cardboard  Aluminum

ProductCan be recycled to make… NewsCardboard, egg cartons, building materials Telephones, magazines, catalogs Building materials Aluminum cansNew aluminum cans, lawn chairs, siding, cookware Glass jars and Bottles New glass jars and bottles Plastic beverage containers Nonfood containers, insulation, carpet yarn, textiles, fiberfill, scouring pads, toys, plastic lumber, crates

Degradable Plastics: Photodegradable Plastic  when it is left in the sun for many weeks, it becomes weak and brittle and eventually breaks into pieces.

Degradable Plastics: Green Plastic  made by blending the sugars in plants with a special chemical agent to make plastic  labeled as green because they are made from living things  considered to be more environmentally friendly than other plastics.  Production requires 20 to 50 percent less fossil fuel than the production of regular plastics does.  When this plastic is buried, the bacteria in the soil eat the sugars and leave the plastic weakened and full of microscopic holes.  The chemical agent gradually causes the long plastic molecules to break into shorter molecules. These two effects combine to cause the plastic to eventually fall apart into small pieces.
