Need details on water-less urinal & biological-blocks

Meghalaya in general gets 12000+ mm of water through rainfall, nevertheless, scarcity of water is a common issue here. I've recently read many articles on water-less urinals which help in conserving the natural resource & keeps the environment clean at the same time too. Bio-blocks are another alternative to this.

I would like to get contatcs of organizations who manufacture "Odour Trap" for the urinals and the ones who manufacturer Bio-blocks. Ay information on the resource support available for this will also be useful.

I'm willing to introduce these products to the common mass so that the water spent in  these activitities could be conserved & at the same time sanitation could be improved. 

Any suggestions & information on this is welcome
