First of all, you need the right climate (average day/night temperatures above 15°C) so HomeBiogas can work optimally.  Second, you need a space with good solar access to put the HomeBiogas. It should be placed outdoors in an easy-to-access area within 20 metres of where you intend to cook.  Finally, you need a regular source of organic waste to feed HomeBiogas. You can use your leftover food scraps from the kitchen, or animal manure.
