Large Scale Kitchen Waste Biogas Plant

Using Kitchen wastes like left over food, Vegetable peel offs, Fruit peel offs, non Edible Flour, Starch etc, Biogas can be generated. Large Scale Units ranging from 100kg to 2000kg can be set up. Medium and large scale units have been already installed at K R hospital, Mysore and Administrative Training Institute (ATI) respectively and JSS Educational Institutes, Suttur, two plants of 100Kg per day capacity are on the verge of completion The Biogas produced from these units can be effectively used for Cooking and also to generate Power for plants with capacity of more than 1000Kg per day

Kitchen Waste Compact Biogas Plant

Kitchen waste compact biogas plant, uses kitchen waste which are daily available at households for the production of biogas, which can be used for cooking. The small unit consists of two PVC tanks of 1000Lts and 750Lts and generates 0.6 m3 of gas everyday for 2Kg of kitchen waste per day. Till date we have successfully installed 60 plus units in Karnataka

Fuel Efficient Biomass Small Cook Stoves

It consists of 2 pans and a heat recovery vessel (2+1). The stove is completely built using locally available materials like Bricks, Red soil, sand etc. and local manpower. The stoves give a overall thermal efficiency of 40% for a burning rate of 1.2 kg firewood per hour. Of this, the first pan accounts for 15%, the second 10% and the third 15%. This burning rate is adequate for cooking a normal meal of rice, sambar and vegetable for a family of five, the cooking getting completed in 60 min.

Fuel Efficient Biomass Large Cook Stove

Cooking in hostels, hotels, and canteens come under this category. Stoves used are 2+1, 1+1, and single pan types. The stove is completely built using locally available materials like Bricks, Red soil, sand etc. and local manpower. This stove gives the advantage of adequate area for heat transfer at the same time providing hot water for subsequent cooking operations.. This stove gives a thermal efficiency of 40-45%.

Fuel Efficient Biomass Bath Water Stove

Fuel efficient Bath stoves can be built for meeting hot water requirements. The combustion is carried out similar to that in the ASTRA Ole and the large cook stoves. Thermal efficiency is 40-45%. The stove is built using locally available material and manpower.

Biomass Based Drier

Recognizing the need for A drier for dehydrating processed food at remote places where there is no access to grid electricity, a biomass fuelled, and thermally efficient drier suitable for small scale drying in rural areas. This design has been successfully field tested for areca, cardamom, and cocoa beans. Also the drier can be successfully deployed for dehydration of fruits and vegetables.

Biomass Gasifier Plant

A biomass gasifier system involves partial combustion and reduction operation of biomass with air under sub-stoichiometric conditions, resulting in generation of producer gas. The Producer gas generated can be used in the existing DG plants for power generation with 80%(gas) and 20%(diesel) ratio or in gas engine with 100% gas without use of any conventional fuel. The plant can be designed from 100 KW up to 200 KW capacity. Fuel can be any solid biomass with bulk density over 250 Kg/m3

Charcoal from leafy litter

Urban solid waste consisting of leafy litter, trimmings of trees and hedges, and paper waste can be charred in this kiln. For a load of 6 kg leaves per batch 2kg char can be obtained. Briquettes can be made from the obtained char.

Hand operated Briquetting Machine

The Charcoal produced in the above kiln is powdered and mixed with suitable binder. Then load it to this briquetting machine and extruded into char briquettes.

Fuel Efficient Charcoal Cooker

It is a non-pressurized cooker in which the char-briquettes are used as fuel. The cooker has a stainless steel body with a built-in charcoal brazier. 100gm of charcoal is sufficient to cook food in 45 min. it is available in 3 sizes.

Bio - Diesel

Diesel (Petroleum) sources are diminishing with time. There exists no energy security to replace crude oil. The alternative to the diesel can be any oil after transesterification. In fact Rudolph Diesel, the discoverer of Diesel engine ran the engine for the first time with peanut oil, but using edible oil as biodiesel is not advisable as it leads to scarcity of food commodities. The oil extracted from NON EDIBLE seeds like pongamia (Honge), Simaruba, Neem, surahonne, naga sampige, caster, jatropha etc. can be used as biodiesel after transesterification. These oils can be used in blend with diesel up to 40% by volume. Karnataka State Biofuel Board has taken up initiatives to popularize the concept of biodiesel in Karnataka.
