One of the most utilized ways to preserve food is to seal it in bags and store them in food grade buckets. With this method you can store a lot of food in a small space, your food will have a very long shelf life, and you can reuse the buckets as many times as you want. But there’s another bonus to using buckets that many people forget: In a long-term disaster you can use them for all sorts of other things. Although most of the uses for buckets listed below will work with any type of bucket, you still need to know how to tell the difference between food-grade and non-food-grade so you don’t mix them up. First, look at the recycling symbol on the bottom. There should be a number between 1 and 7 inside a triangle made of arrows. The numbers that indicate food-grade are 1, 2, 4, and 5, but the best is 2 because it means the bucket is made of high-density polyethylene, one of the most stable forms of plastic. If there isn’t a number on the bottom of the bucket, check for other symbols such as a cup and fork (food-safe), radiating waves (microwave-safe), or a snowflake (freezer-safe). All these indicate the bucket was designed to contain food. If none of those symbols are there, look for a price tag or manufacturer’s label for information.
1. Build A Rocket Stove
Large metal buckets are great for making rocket stoves. In case you don’t know, rocket stoves are cheap to make and incredibly efficient. They heat up food and water very quickly and run on small branches and twigs. The principle behind a rocket stove is simple–rather than cooking on an open fire, you burn wood in an insulated chimney. Rocket stoves are highly efficient and easy to make. They run on twigs, so you can avoid cutting down a whole tree just to cook dinner.
