Rising consumer consciousness is continuing to heighten demand for plastic feedstock that isn’t quite so harmful to our planet. There are a number of strategies for limiting the impact of plastic production, and no single one is likely to solve the sustainability problem on its own.
Taken together, though, the four strategies introduced below represent real promise for limiting the amount of non-renewable feedstock associated with plastic production. They help us to make better use of the materials that have already been produced and ensure that we’re not pushing the problem of petroleum-based plastic production off on the next generation.
We’d like to take some time to call attention to these strategies — especially some of the lesser-known ones — highlighting the merits of each strategy while touching on why sustainable plastics matter at all.
“It would be silly to suggest that we do away with plastics. They are too valuable, too ubiquitous and too useful. What we should do away with, however, is the way that they are made, some of the ways that we use them, and certainly what we do with them when they have done their job.” -- Tom McKeag
What plastics are made of, the way we use them and what we do with them after they’re gone are themes touched on throughout our strategies for more sustainable plastic production. As McKeag suggests, there’s not one thing wrong with the way we’re producing plastics today. The entire lifecycle of these materials needs to be addressed; from the way we select the materials we use to the ways we’re able to dispose of them after their useful life has ended.
Here are our four ways to make plastics more sustainable:
Reducing petroleum feedstock by 25 percent can decrease greenhouse gas emissions equivalent to removing 16.5 million passenger cars from the road every year.
Reducing petroleum feedstock in plastics by just 10 percent saves 280 million barrels of oil a year, reducing CO2 emissions by the equivalent of the CO2 sequestered by 250 million acres of forest.
Though plastic recycling has come a long way, it’s still a process that’s far from efficient. A number of problems, such as the difficulty in collecting and sorting different types of plastic materials, have so far kept high percentages of plastic waste from being effectively recycled. Here's how much one ton of recycled place could save in terms of oil, energy or landfill space:
Solid waste landfills are one of the largest man-made source of methane gas (CH4) in the United States. Methane is a powerful greenhouse gas, 23 times more effective at trapping heat in the atmosphere than CO2.
Increasing the composting of food scraps by 25 percent in the U.S. would decrease GHG emissions equivalent to saving more than 15 million barrels of oil per year.
And reducing waste disposed in landfills can have climate benefits equivalent to removing 21 percent of the U.S. coal-fired power plants.
While the problems of waste and pollution are large and complex, sincere efforts on all of these fronts will decrease the environmental impact of the plastics products we use every day.
