Permaculture Alternatives to Waste-to-Energy (W2E)

Waste-to-energy (W2E), particularly incineration, is being promoted as a good alternative to landfills – it gets rid of all that plastic we use and generate energy, right? In this article I’d like to first outline what’s wrong with W2E and then talk about permaculture alternatives.

So What Is Wrong With W2E Incineration?

W2E is a continuation of the ‘take-make-dispose’ economy which lulls people into the belief that we can continue our wasteful ways without changing our behaviour. But we live on a finite planet and most environmental harm comes at the extraction stage – so why would we want to burn resources and get rid of them? It doesn’t make sense. We need to get away from an extractive to a regenerative culture.

There are multiple negative impacts of W2E plants, which are seeing many being decommissioned internationally. For example, the toxic ash that remains after burning still has to be disposed of in a landfill.  This can be up to 25% of the original volume of waste material, but with more toxicity. So incinerators don’t do away with the need for a landfill, instead they require a landfill for more toxic and dangerous waste.

Aside from the toxic ash, W2E incineration plants create an on-going demand for waste to fuel the incinerator. They are very expensive to build, have huge embodied energy, and once built, have to run for years to get a return, locking us into a destructive system.  Right now our planet’s ability to sustain life is seriously at risk. We cannot afford the luxury of investing in bad ideas.

Our young people are calling for Climate Action now and we have a major responsibility to urgently reduce emissions. Incinerators create emissions. New Zealand’s electricity is currently 80% clean (water, wind, solar, geothermal) so why would we want to start burning trash to generate power?  It just doesn’t add up environmentally, economically or socially.

Getting it wrong on recycling

Getting it wrong on recycling

Let’s see what those disparaging America’s rate of recycling as “too high” either get completely wrong or fail to understand. You can read recent commentary suggesting that the recycling rate is too high herehere and here.

The number one complaint is that it costs more to recycle some categories of waste than to put them into a landfill. What the critics fail to comprehend is that unlike a couple of generations ago when most landfills were owned and run by local governments, today most are run by profit-making enterprises such as Waste Management Inc. and Republic Services Inc. which haul some 80 percent of the nation’s refuse. Those enterprises developed their large centralized landfills for the purpose of keeping down their disposal costs.

Since the private waste disposal industry has organized its infrastructure around cheap landfill disposal, it’s no wonder that landfilling seems like the most cost-effective option. It follows that if we Americans had built a waste infrastructure with the goal of zero waste as Germany did, our infrastructure would naturally have delivered lower costs for recycling than it does.

The Germans landfill about 1 percent of their waste compared to America’s 68 percent. Germans recycle about 70 percent of their waste and burn almost all the rest to produce energy. Americans recycle about 25 percent of their waste and burn about 7 percent.

Consider this analogy. You can make your house energy-efficient in two ways. You can build it to be energy-efficient in the first place. Or, you can add energy-efficient features later on. Which do you think would be more cost-effective?

That’s what we’ve been facing with the boom in recycling. We are retrofitting a system designed for cheap landfilling rather than building a system designed for cheap recycling (which ought to be our goal).
