Waste to Energy Solutions by YellowHaze

Waste to Electricity:

Electricity Production from Waste takes place mostly through combustion (Incineration) process where waste is Incinerated to produce heat, which then is used to produce electricity. Other methods of electricity production from waste include indirect methods where waste is used to produce a combustible fuel commodity, such as methane, methanol, ethanol or synthetic fuels and then these products are used to produce electricity.

Plastic Waste to Diesel:

Plastic is derived from crude oil through a process called polymerization and at the plant thermo-chemical depolymerisation process is done to reconvert plastic to crude oil. In this process #plasticwaste is heated in a reactor at a very high temperature of between 350-600 degree Celsius in the absence of oxygen, and three components from it –hydrocarbon gases, toxic mix of gases called syngas and carbon black – are derived. Afterwards pyrolysis oil is derived, which is a high grade diesel variant after the hydrocarbon gases are condensed. Instead of letting the toxic gases out into the atmosphere, these are captured in a balloon and reintroduced as heating agents into a process. The entire process is not only energy efficient but also completely green. Also, the process is zero effluent and zero emission.

The #Plasticwaste to Diesel plants convert about 1 tonne of plastic waste into 150-200 litres of diesel, which will sell at a cost of Rs 45-50 per litre. The diesel is not usually auto-grade but can be used as substitute for diesel generators and factory set up. Instead of using furnace oil, factories can use this oil. One of the main advantages of this oil is that it is 25 per cent cheaper than furnace oil. Also, its very low in sulphur content and, hence, less polluting.

Organic Waste to Biogas

Bio-gas is produced naturally through a process of anaerobic decomposition from waste / biomass sources like agriculture residue, cattle dung, sugarcane press mud, vegetable market waste, slaughterhouse waste, municipal solid waste, sewage treatment plant waste and industrial wastes & effluents etc. After purification, it is compressed and called CBG, which has pure methane content of over 95%. Such projects are being set up in a number of industry sectors namely distillery, paper and pulp solvent extraction, dairy, starch industries, sugar mills, pharmaceutical industries, etc., and sewage treatment plants.

Food Waste to Biogas for Cooking

Institutions like residential schools, colleges, medical academic institutions, hospitals, NGO’s, hotels, companies that have institutional setup of mess (cafeteria’s) can utilise their uncooked & cooked food waste to generate bio-gas that can be used as substitute for cooking LPG gas. As per our data, 100 Kgs of food waste provides  approximately 7 Kgs equivalent of LPG gas. Our modern food-waste to biogas plants are space efficient with 1 ton waste per day processing plant occupying only about 50 square meters of area.
