Make the best choice for the environment.
“It’s not easy being green,” according to Kermit the Frog. So many choices, so many voices.
When it comes to consumer products, few are environmentally perfect. Each has qualities, pro and con, that make it either an eco-plus or an eco-bust.
This is particularly true when it comes to the age-old debate on Paper vs. Plastic. You most likely made up your mind years ago on the correct green way to go, so your answer to the checker at the supermarket is routine by now. But deep down inside you may still question whether or not you’re right. Choosing plastic may help save a tree, but selecting paper may keep landfills to a minimum.
For most of us, our choice is based on an either-or approach adopted when we first became environmentally aware. But the 1990s have shown the answer to be far more complex. The real concern is not plastic vs paper so much as it is the problems created by the huge amount of solid waste both these common household materials contribute to the environment. The imperative has become to stop putting so much of either material into landfills and incinerators. Recycling minimizes waste.
Therefore, your number one correct response at the supermarket is to give the clerk a cloth bag of your own for your groceries—a bag you can reuse over and over. The paper bag your supermarket offers is probably not a good choice because it’s made of virgin paper. Just as the plastic bag is molded from virgin resin. Recycled paper? Good. Recycled plastic. Good. Recyclable cloth bags? Best of all.
For that perfect summer picnic, should you opt for paper or plastic containers? For the sake of accuracy, plastic hot-beverage cups are not made of Styrofoam, the trade name for a Dow Chemical insulation construction material; they are made of foamed polystyrene. These items are not currently recyclable, so rinse and reuse them. If you choose paper cups, dispose of them in a compost heap where they will biodegrade. Should you opt for paper or plastic plates for your summer picnic? If you choose paper plates, you also should dispose of them in a compost heap; if the plastic is your choice, rinse and reuse them. Or buy a picnic basket and use your own household china and flatware, which you can rinse and reuse.
Plastic is a byproduct of petroleum and natural gas, and its manufacture depletes oil reserves—although all the plastic produced comes from a very small percentage of the oil produced; its processing emits pollutants; and because it’s inorganic, it doesn’t degrade in landfills. Plastic is truly the world’s most visible form of litter.
Every recycling program has an effect on our environment. For example, in 1998 in Denver, Colorado, alone, 9,900 tons of newspapers were recycled, saving 167,960 pulp trees grown to make paper, and 260 tons of plastic, creating 45,000 ski jackets made from recycled materials and 2,000 plastic-lumber park benches. Also recycled were 2,500 tons of glass, saving 19,563 gallons of fuel used for manufacturing; 130 tons of aluminum, saving 4,420 tons of bauxite ore used to make cans; and 260 tons of steel, saving 650,000 pounds of iron ore, 260,000 pounds of coal, and 10,400 pounds of limestone.

A total of 3 513 100 tonnes of plastics were consumed in Australia in 2016–17. Because literally thousands of different plastics cannot be melted together—their molecules don’t mix—sorting is a major obstacle to plastics recycling. However, the handling and reclaiming of post-consumer plastics
The properties of PET (polyethylene terephthalate) soda bottles and HDPE (high-density polyethylene) bottles and containers make them good candidates for recycling into fibers, carpet, and lumber. Some polystyrene products also are being recovered for similar uses. But with a very few exceptions, such as recycling computer housings into roof shingles, the recycling of non-packaging plastic is a challenge for the future.
However, reports the Polystyrene Packaging Council, polystyrene packaging—including cups, plates, bowls, clamshells, meat trays, egg cartons, yogurt ,and cottage-cheese containers, and cutlery—accounts for less than one percent of solid waste in the United States. And these products have been source-reduced 9 percent since 1974, which means that 9 percent less polystyrene is used today to manufacture the same goods.
Biodegradable plastics, which are primarily cornstarch-based, have been marketed with mixed results in the past decade for products ranging from grocery bags to golf tees. To replace the pervasive packing “peanuts” that love to cling, Eco-Foam—a new
With packaging, the issue is not so much what it is made of as how much it weighs. The use for food protection of paper, foils, and plastic or plastic films—singly or in combination—should be encouraged as replacements for heavier storage containers. More importantly, you should continue to buy concentrates and refills, large sizes, and products with less and thinner packaging to reinforce manufacturers’ efforts to produce green products. We may say we want environmentally friendly products, but at the same time we may buy more convenience products like microwavable foods and tamper-resistant bottles that require elaborate packaging, which, in turn, generates more waste.
Remember the uproar over disposable vs. cloth diapers in the late 1980s? Overnight it seemed that disposable diapers became ecologically unsound. Disposables produce four times as much trash in landfills, noted one critic. But, another critic noted, over the course of a year disposable diapers consume half as much energy as cloth ones, use one-quarter as much water, and generate one-seventh the water pollution.
Paper or plastic? Your choice, and not an easy one.

Just what does degrade in a landfill? Not much. Landfills are designed to keep solid waste from degrading. This containment prevents the formation of harmful gases and bacteria that can leach toxic substances into the water supply and pollute the air. In fact, landfills are covered with dirt to keep out the oxygen and moisture that bacteria thrive on.
Indeed, in a 1980s landmark analysis of landfill content, archaeologist William Rathje of the University of Arizona found newspaper buried for decades that was completely readable, and food such as bananas that was almost intact. He also found that disposable diapers, with the exception of their outer layer, degraded no more slowly than much of the landfill’s paper and took up no more space.
Composting encourages biodegradation. This is because the material in a compost heap is food for the microorganisms present. The more microbial life there is to consume the biodegradable material, the faster material decomposes.
Where recycling is not economically or technically feasible, non-recyclable and solid-paper products such as paper napkins, cups and plates, pizza boxes, and coffee filters provide composting benefits when combined with other organics, according to the American Forest and Paper Association. National Starch and Chemical Company’s Eco-Foam loosefill also is said to be readily biodegradable in compost heaps.
