Which Plastics Are Safe to Use in Your Home? By David Johnston and Kim Master Care2.com The news about plastics has been pretty alarming lately, causing some of us to go dashing for the water bottles to see what kind of plastic they are -- and find out if we've been unwittingly poisoning our children and ourselves with chemicals leaching into the water from them. Simple Solution: If you've been concerned, here is a handy chart that identifies the good, bad, and ok plastics and where they are found. 1. Polyethylene terephthalate (PET or PETE) Used to make soft drink, water, sports drink, ketchup and salad dressing bottles, and peanut butter, pickle, jelly and jam jars. GOOD: Not known to leach any chemicals that are suspected of causing cancer or disrupting hormones. 2. High density polyethylene (HDPE) Milk, water and juice bottles, yogurt and margarine tubs, cereal box liners, and grocery, trash and retail bags. GOOD: Not known to leach any chemicals that are suspected of causing cancer or disrupting hormones. 3. Polyvinyl chloride (V or PVC) Most cling-wrapped meats, cheeses and other foods sold in delicatessens and groceries are wrapped in PVC. BAD: To soften into its flexible form, manufacturers add "plasticizers" during production. Traces of these chemicals can leach out of PVC when in contact with foods. According to the National Institutes of Health, di-2-ethylhexyl phthalate (DEHP), commonly found in PVC, is a suspected human carcinogen. 4. Low density polyethylene (LDPE) Some bread and frozen food bags and squeezable bottles. OK: Not known to leach any chemicals that are suspected of causing cancer or disrupting hormones, but not as widely recycled as #1 or #2. 5. Polypropylene (PP) Some ketchup bottles and yogurt and margarine tubs. OK: Hazardous during production, but not known to leach any chemicals that are suspected of causing cancer or disrupting hormones. Not as widely recycled as #1 and #2. 6. Polystyrene (PS) Foam insulation and also for hard applications (e.g. cups, some toys) BAD: Benzene (material used in production) is a known human carcinogen. Butadiene and styrene (the basic building block of the plastic) are suspected carcinogens. Energy intensive and poor recycling. 7. Other (usually polycarbonate) Baby bottles, microwave ovenware, eating utensils, plastic coating for metal cans BAD: Made with biphenyl-A, a chemical invented in the 1930s in search for synthetic estrogens. A hormone disruptor. Simulates the action of estrogen when tested in human breast cancer studies. Can leach into food as product ages. - Adapted from Green Remodeling, by David Johnston and Kim Master (New Society Publishers, 2004). What is Composting? Compost is organic material that can be used as a soil amendment or as a medium to grow plants. Mature compost is a stable material with a content called humus that is dark brown or black and has a soil-like, earthy smell. It is created by: combining organic wastes (e.g., yard trimmings, food wastes, manures) in proper ratios into piles, rows, or vessels; adding bulking agents (e.g., wood chips) as necessary to accelerate the breakdown of organic materials; and allowing the finished material to fully stabilize and mature through a curing process. Did You Know That Compost Can While yard trimmings recovery typically involves leaf compost and mulch, yard trimmings can also be combined with other organic waste, such as food residuals, animal manure, and biosolids to produce a variety of products with slightly different chemical and physical characteristics. In contrast to yard trimmings recovery, only 2.6 percent of food waste was composted in 2000. The cost-prohibitive nature of residential food waste separation and collection is the primary deterrent to expanding food waste recovery efforts. Yet in many communities, edible food residuals are donated to the needy, while inedible food residuals are blended into compost or reprocessed into animal feed. In some areas, composting operations are working with high-volume commercial and institutional food producers to recover their food byproducts, saving these firms significant disposal costs.
