Criticize recycling and you may as well be using a fume-spewing chainsaw to chop down ancient redwoods, as far as most environmentalists are concerned. But recent research into the environmental costs and benefits and some tough-to-ignore market realities have even the most ardent of recycling fans questioning the current system.
No one is saying that using old things to make new things is intrinsically a bad idea, but consensus is building around the idea that the system used today in the United States on balance benefits neither the economy nor the environment.
In general, local governments take responsibility for recycling. The practice can deliver profits to city and county budgets when commodity prices are high for recycled goods, but it turns recycling into an unwanted cost when commodity markets dip. And recycling is not cheap. According to Bucknell University economist Thomas Kinnaman, the energy, labor and machinery necessary to recycle materials is roughly double the amount needed to simply landfill those materials.
Right now, that equation is being further thrown off by fluctuations in the commodity market. For example, the prices for recycled plastic have dropped dramatically, which has some governments, many of which have been selling their plastic recyclables for the last several years, re-thinking their policies around the material now that they may have to pay for it to be recycled. It’s a decision being driven not by waste management goals or environmental concerns, but for economic reasons that could feasibly change in the next couple of years.
Not only that, but in some cases recycling isn’t even what’s best for the environment.
The solution, according to economists, activists and many in the design community, is to get smarter about both the design and disposal of materials, and shift responsibility away from local governments and into the hands of manufacturers.
Material World
Because most people dispose of used aluminum, paper, plastic and glass in the same way — throw them into a bin and forget about them — it’s easy to think that all recycled materials are created equal. But this couldn’t be further from the truth. Each material has a unique value, determined by the rarity of the virgin resource and the price the recycled material fetches on the commodity market. The recycling process for each also requires a different amount of water and energy and comes with a unique (and sometimes hefty) carbon footprint.
All of this suggests it makes more sense to recycle some materials than others from an economic and environmental standpoint.
A recent study by Kinnaman provides research to back up that assertion. Using Japan as his test case — because the country makes available all of its municipal cost data for recycling — Kinnaman evaluated the cost of recycling each material, the energy and emissions involved in recycling, and various benefits (including simply feeling good about doing something believed to have an environmental or social benefit). He came to the controversial conclusion that an optimal recycling rate in most countries would probably be around 10 percent of goods.
But not just any 10 percent, Kinnaman cautions. To get the most benefit with the least cost, we should be recycling more of some items and less — or even none — of others. “Although the optimal overall recycling rate may be only 10%, the composition of that 10% should contain primarily aluminum, other metals and some forms of paper, notably cardboard and other source[s] of fiber,” he wrote in a follow-up piece in The Conversation. “Optimal recycling rates for these materials may be near 100% while optimal rates of recycling plastic and glass might be zero.”
