thank you all.
let me be a little more specific.
this is a solution i am trying to find for very poor people living in very mountainous terrein in a country in Africa.
they mainly have donkeys as their work animal and not many cattle. the dung is seen to be necessary for the earth / soil so seen not to be an option to burn this and there would not be enough.
i would need to come up with a product to import together with a heater structure, keeping the heat inside the huts. it is extremely cold with no electricity as an option.
the wood is scarce as they have used this over years to cook with. the heat is required all day.
there are no production sites. it is a case of finding a solution and raising the funds to deliver.
may i ask how does vermiculite work? due to the light weight and high burning temperatures i thought it would be a good option as it is transportable by the donkeys to the villages ?
please note i am by far not an expert in this field and am a management consultant trying to find a solution to a long term problem. your help is appreciated with enormous gratitude.
thank you
