What not to compost?
thank you for your very informative article about the subject of compost toilets. I always enjoy the topics you cover on Greenidiom.com.
I've got a question. I recently read that one should not compost sawdust from CCA pressure treated lumber because it is apparently saturated with cancer-causing chemicals such as chromated copper arsenate. This material is apparently available to the consumers in many parts of the world. Is this true? If so how can I make sure to use only sawdust that is non contaminated with this kind of poison?
I would love to start my own compost toilet but this subject of poisonous sawdust scares me a little.
I am looking forward to hear from you and hope you can help me.
