Recycling isn’t enough when demand for aluminum is soaring. We have to use less of the stuff.
Everybody knows that aluminum is recyclable; it is the most valuable thing in the bin. Everyone has heard the statistic that it takes 92 percent less energy to make a can out of recycled aluminum than it does to make one out of virgin aluminum. And everyone feels good about this; that is why recycling was invented, to make you feel good about consuming disposables.
But only two-thirds of aluminum cans are actually recycled, and so a lot of virgin aluminum still has to be made, a lot of bauxite has to be mined, and a lot of electricity has to be used to separate out the aluminum. In fact, because of increased demand for aluminum in cars and trucks, primary production of aluminum is skyrocketing.
According to Richard Woodbury of the CBC, some brewers are refusing to buy into the beer can hype. When Henry Pedro co-founded Boxing Rock Brewing in Nova Scotia, he refused to use cans because of the environmental damage caused by bauxite mining and – because he is in Canada – he had access to refillable bottles.

Other breweries justify their use of cans because that’s what the customers want; Joshua Counsil, the marketing director of Good Robot brewing told the CBC:
This being TreeHugger, where we make decisions purely on environmental reasons, the answer is pretty clear: We have to do everything we can to reduce primary aluminum production, particularly now that the American Government has put a tariff on imported aluminum that is made using hydro-electric power. Single-use packaging like aluminum cans should be the first thing on our list to go. As Carl Zimring concluded in his book Aluminum Upcycled: sustainable design in historical perspective, recycling and even upcycling of aluminum doesn’t work if we keep having to mine more bauxite and extract more aluminum.
Every can of pop or beer just compounds the problem. Recycling isn’t enough; we just have to use less of the stuff, starting with single-use packaging.
