Re: [papercreters] Re: New Scientific Paper



Yes, Florida is quite warm and humid, I understand - several other southern states as well. Do we have anyone on the list who has been experimenting with papercrete in that type of climate? Are you including a greater percentage of cement? Any estimate of drying times? Anybody using something like a lumber/firewood drying shed to cure blocks?

I live and work in Indonesia and a close colleage also working here is from India. There is, to some extent, less of the "throw away" behaviour embedded into the cultures of these poorer countries. Indeed there are the "constantly burning landfills" - but overall there is less waste in poor countries where a large portion of the people are scrounging to survive. And in these poor countries there is still a very large element of the "traditional markets" that do not require all the processing and packaging.

For some years now (nearly 10), waste paper (and plastic materials) has been on the list of scrap dealers. My Indian colleage says the situation in many parts of India is similar to Indonesia.

The biggest waste in most of these poor countries is plastic bags that replaced wrappings of not so long ago like banana leaves and other natural materials. Paper is not the largest problem of the trash - but this plastic is.

The higher ambient temps and humidity mandate a labrinth of trial and error adjustments to possible papercrete mixtures that are suitable - and this New Scientific Paper has shed more light on that than anything else I have seen so far..

BTW - to my knowledge - doesn't Florida and some states like it have high temps and humidity?

Cheers, Dave
