In Argentina on weekends we cook barbecue with fire generated with woods and paperboard. We don't use gas like in the USA. I know there are some things that cause cancer and other illness like OSB wood because it has glues. So I would like to know which wood, paperboard, paper, etc. is not healthy. I'm thinking about painted paper.

  • This question appears to be off-topic because it is not directly related to sustainability.

  • Why not? The question is about (dangerous, imo) practices to keep cooking techniques more sustainable--using replaceable fuels instead of fossil fuels. Identifying bad fuels to use for cooking is totally on topic. Apr 10 '14 at 17:28
