We recycle or reuse what we can and burn the rest. I know, bad for the ozone layer probably, but at least none of our waste goes into a landfill - and most of it is paper products, anyway; feed bags, food packaging, cardboard boxes. Our solar system produces much of our own electricity, and we burn clean LP gas for heat. We don't drive much since we're both retired and homebodies. Diesel fuel for the tractor and such takes a chunk out of our budget, though. We don't very well conserve water, since the livestock and garden use so much and it's abundant in our region anyway. I do have an HE washer that I run only on full loads, and wash dishes only on full loads, bathe 2x a week.
We buy sodas, but usually in cans or 2-liter bottles; the cans are sold with our scrap metal for recycling, and the bottles are reused for emergency water storage and ice for the chicken processing tubs. Likewise, I reuse plastic milk jugs. But mostly we drink iced tea or water in our own bottles. We grow as much of our own food as we can, including beef and pork. I spend summers canning produce and fruit, and processing chickens. I'm growing mealworms to help with the chickens, and of course no produce scraps ever go to waste. We don't have much in leftovers; I'm being more frugal about cooking, and freezing meal-sized portions if there's enough. We waste very little food.
I wish we could spend less on farm expenses, though. The tractor and bobcat repairs are crippling us financially. And we go through buckets and buckets of hydraulic oil, that gets leaked all over the damn place. (I reuse those buckets for everything!)
