ABSTRACT

 

In the rural areas, green leaves and stems mainly from vegetable crops, banana, grapes, etc., are underutilized after harvesting. Some green leaves and stem are used as fodder for animals which is not completely digested by them. Otherwise they are burned or thrown away. Green leaves contain proteinous matter, waxes, resin, lignin and cellulose. Many people are under impression that green leaves and stems produce good manure. They have no idea that cellulose and lignin in these green leaves cannot give good quality of manure and even cannot be decomposed easily. Our idea of a Bio-Village will give biogas to the villagers. The green leaves and the stems are crushed to produce juice. This juice is fermented to produce biogas which can be used for cooking. Also the residual lignin + cellulose (lingo-cellulose) can be used to make the doors and windows of houses, furniture etc. Here, the ligno-cellulose bonds are partially broken and made them to be in-situ bonds again to form dense hard-board. The strength of ligno-cellulose can be enhanced by adding phenol resin to the ligno-cellulose residue. We assume that a group of few villages come forward to produce biogas centrally which further can be distributed amongst them. The low cost set up for manufacture of particle wood can also be established in the village which can provide the employment to the villagers. Gandhiji always said that Villages should prosper, then Country will prosper and then the World.
