Area of interest:

 
Carrying out R,D & D on decentralized energy technologies (biogas plants and peripherals) and energy system integration into rural life from 1980. Early studies had revealed, being energy resource deficient, rural South India will continue to depend on biomass as the primary energy resource - biogas option has a great potential to convert all compostable organics to fuel gas and rich organic manure. Cattle dung based biogas plants have already spread but have finite potential. Thus new processes / technology for other biomass have to be developed. This is my conviction. Biomass biogas plants can be built to meet all current and future base-load energy needs in villages. Unless such plants are built, operated and managed by people in rural areas, there is not likely to be major impact on policy. My efforts is largely in R&D on biomass biogas plants, demonstrating their use in various areas, making them more attractive to end-users and finally pushing towards a green bio-energy policy. R,D & D efforts are spread over four areas, namely
 
  1. BIOGAS: Semi-continuous Solid Phase and Plug Flow type Biogas Fermenters for untreated herbaceous biomass, USW other fermentable wastes. Low cost plastic film bag type biogas plants, Resource and Cash Recovery Techniques from spent biogas plant feed stocks e.g. mushroom, vermin-compost, safe pest repellants, etc. Biogas production from agro-processing wastes: whey, coffee pulping, small-town sewage etc; Sand-bed filters for water recovery from biogas spent slurry: Evaluation and policy recommendations.
  2. DECENTRALIZED / SUSTATAINBALE RURAL ENERGY: Micro-planning Sustainable Biomass Energy Planning for village agricultural ecosystems - total biomass energy villages, Bioenergy-based irrigation in semi-arid areas - equitable access and sustainable use models.
  3. WATER PURIFICATION: Low cost rapid fecal contamination test, drinking water purification with silvered surfaces: low cost water purifier for rural India.
  4. APPROPRIATE AGRICULTURAL TECHNOLOGIES: Participatory Technology Development, technology acceptance and adaption among rural areas especially among resource poor farmers.
New design biogas plants are at different stages of field testing, demonstration and dissemination phases - depending upon the sector's affordability. At least three different types of biomass based biogas plants are being disseminated - the plug-flow like biogas plants, solid-state stratified bed (SSB) biogas fermentor and biomass immobilized bioreactors for coffee and agro-processing waste waters.
