You didn't say what the project at home you wanted to do with them was? If it is for livestock feed, store things and such then go for it but to reuse for food storage unless it is wrapped in something I wouldn't. Storing canned goods etc. would be ok. I just use them for livestock and winter storage for blankets that are in plastic bags and barrels are placed in the barn. No rats or roaches as I tape the rims shut. Sometimes dampness can cause a problem so I put some charcoal briquettes in each barrel to absorb the moisture. Everything in the south has a moisture problem. lol.
