Produce No Waste

In a natural system, nothing is wasted. A leaf falls, decomposes, feeds the tree above it. An animal dies, becomes food for scavengers and microbes, returns to soil. Every output is somebody's input. The system runs in closed loops.

Mollison's third principle: produce no waste. Or put another way — every output of one element should be designed to be the input of another. When something is leaving your site as "garbage," that's a design failure. The waste is real; the design just hasn't caught up yet.

Everything your site produces falls into one of three buckets:

• Feed back into the system — kitchen scraps to compost, leaves to mulch, prunings to firewood. The biggest bucket in a well-designed system.
• Store for later — preserved food, saved seeds, dried herbs. Outputs that you'll consume yourself in time.
• Leaves the site — surplus to neighbors, recycling, landfill. The smallest bucket — and the one a permaculture design tries to shrink.

The job is to push as much as possible from the third bucket into the first two.

Most homes start with kitchen waste because it's the easiest. A typical household generates 4-6 lbs of kitchen scraps a week. That's 200-300 lbs a year going to landfill — and it could all be soil.

Routes for kitchen scraps:

• Compost pile — for everything plant-based. Bedrock of the system.
• Worm bin — for fruit and vegetable scraps, coffee grounds, paper. Produces the richest fertilizer on earth.
• Chickens — for almost everything edible. Get eggs and pest control on the way to compost.
• Bokashi bucket — for what compost can't handle (meat, dairy, oily scraps). Ferments and then gets buried.

Most kitchens can route 95%+ of their food waste this way. The remaining 5% is bones the dog can't have and the occasional wrapper.

Garden output is even bigger than kitchen output by volume. Every pulled weed, every pruning, every spent plant, every leaf that falls — all of it can be designed back in.

• Chop and drop. Pull a weed, cut it into pieces, leave it on the soil where it grew. The plant's nutrients return to the same square foot it pulled them from.
• Mulch piles in place. Rake autumn leaves directly onto garden beds where they'll break down by spring. Don't even bag them.
• Habitat piles. Stack prunings in a corner. Rotting wood becomes habitat for beetles, lizards, salamanders, and beneficial insects.
• Cover crops. Plant a quick-growing crop (clover, vetch, buckwheat) on bare beds between vegetables. Grow biomass while the bed isn't producing food, then chop and drop it for the next round.
• Coppice. Some trees (willow, hazel, mulberry) can be cut to the ground every few years and they regrow stronger. Free firewood and biomass forever.

The biggest waste stream from a typical home isn't kitchen or garden — it's human waste and water. Closing those loops is the most powerful and the most culturally taboo.

• Greywater (sink, shower, washing machine drain water) can be diverted into garden beds. A simple greywater system requires no electricity and waters trees indefinitely.
• Composting toilets turn human waste into safe soil amendment over a 1-2 year cycle. Used worldwide for decades. Code-compliant systems exist.
• Humanure is real — but it requires care, knowledge, and willingness to handle a topic most people avoid. Don't start here unless you're committed to learning the safety practices.

These systems aren't for every household. But understanding that they exist — and that millions of people use them safely — changes how you think about "waste."

Even with full closed-loop systems, some waste genuinely leaves. That's OK.

• Plastic packaging — recycle what you can, refuse what you can ahead of buying it.
• Bones, hard shells — eventually compost but slowly. Some sites bury them in long-term beds.
• Industrial-process outputs (treated wood, painted materials) — these don't belong in your loops. Deal with them as conventional waste.

The metric is: how small can the "leaves the site" pile get? A conventional household fills a 96-gallon trash bin weekly. A serious permaculture household can run a small kitchen-scraps-only bag every other week.

Produce no waste is the principle that turns "trash" into "uncashed checks."

What to take away

• Waste is just resources in the wrong place. Every output should become an input.
• Three buckets — feed back, store for later, leaves the site. Goal: shrink the third.
• Kitchen first, garden second. Compost, worm bin, chickens, bokashi.
• Cover crops and chop-and-drop are how you close the garden loop.
• Greywater and composting toilets close the biggest loops most people ignore.

Mistakes to skip

• Don't set up everything at once. One loop at a time, well-tuned, beats five half-broken systems.
• Don't buy fancy gear before learning the basic version. A homemade compost pile teaches you what a $400 tumbler hides.
• Don't feel guilty about the residual waste. Some leaves the site. The goal is "as little as reasonably possible," not zero.
