I'm not sure how much of this is being green, and how much of it is just fallout from how I live my life, but here goes:
* I compost all my food waste. Since I'm vegan, almost all waste from the kitchen goes onto the compost pile, which eventually is turned into the soil for the vegetable garden.
* I grow vegetables using water-wise methods, growing varieties that do well in my area. For example, smaller varieties of tomatoes take less watering, and produce more for a longer period in my area's hot, dry climate than larger ones, so I grow cherry tomatoes.
* I use the containers from our vegan butter substitute to sprout seeds and grow seedlings. When the seedlings are ready to plant in the garden, the containers go to the recycle bin.
* Cardboard boxes get broken down into long strips, which are used under pavers for garden paths. They keep the weeds down, and decay well. Once a year, I pull up any paths that are getting weedy, replace the cardboard, and throw the pavers back down.
* I buy in bulk, and reuse the packaging. Anything bought in bulk in a plastic bag goes into a glass container when it gets home, and the bag is used for paper trash in the kitchen. Most of the glass containers are old mayo or peanut butter jars, with Mason jar lids.
* If there's any trash left after all that, it gets sorted and recycled. I put trash out maybe once a month, compared to my neighbors' twice a week. I just don't have much to throw out.
