An Innovative Waste-To-Energy Solution - BIOTHENE Technology.
Energy & Nutrients from Solid Trash Automated Recovery System [EN-STAR] is a revolutionary integrated wasted hydrocarbon recovery system suited for solid wastes including Municipal Solid Waste (MSW), Agricultural Waste, Sewage Waste, Water Hyacinth, Food & Kitchen Waste, etc.
As per estimates more than 55 million tons of MSW is generated in India per year with an estimated yearly increase of about 5% to 8%. it is assessed that solid waste generated in small, medium and large cities and towns in India is about 0.1 kg, 0.3 — 0.4 kg and 0.5 kg per capita per day respectively. The estimated annual increase in per capita waste generation is about 1.33 % per year.
The total estimated potential for Energy from all MSW across India is about 1457 MW (2002). MNRE estimates the energy recovery potential from municipal solid wastes to be about 1500 MW and this could go up to 5,200 MW by 2017 – 18.
An Unsegregated Waste Management System
In India, the biodegradable portion dominates the bulk of MSW. This is mainly due to food and yard waste.Segregation of MSW is a major challenge. Manual segregation is an inefficient and ineffective process.
In the area of municipal solid waste, EN-STAR technology is ideally suited for automated segregation and processing of unsegregated waste to meet the needs of developing countries. The un-segregated waste is treated with water at high temperature and pressure resulting in leachate formation, thereby segregating the hydrocarbons from inorganics for further processing. The Inorganic waste Is passed through a density separator to segregate plastics, metals, wood, glasses,etc. Residual water will be recovered from the leachate after processing using BOOMTUBE FP-STAR, a patented wastewater treatment technology and recycled back in the process.
In the area of non-municipal waste, solid hydrocarbons like agriculture, water hyacinth, etc. are pulverized, diluted and directly fed for processing.
The level and quality of segregation is difficult to be ensured to the level required by the subsequent process of anaerobic decomposition of organic part. To solve this problem, MSW is fed into a Leachate Extractor, where it is washed with water at high temperature and high pressure. The extreme condition ensures that most of the organic matter is converted to Leachate (organic matter slurry) and is collected in an underground Leachate holding tank. The inorganic matter remaining in the Leachate Extractor is sanitized and then passed through a Trommel Screen where the lighter plastics and the heavier solid organic matter like wood, bottles, metals, etc are separated.
The wasted hydrocarbon (leachate from municipal waste or pulverized solids) is fed into reactors for bio-mining and gas refining processes, based on patented MIBR technology. This ensures that the natural gas produced is Grid Grade (IS 16087:2013), high in methane content (95 to 97%), free from Hydrogen Sulphide (H2S) & Carbon Monoxide (CO) and odorless. The entire process is safe and causes very minimum or no air pollution. No incineration or burning is used in the process making it Pollute-Zero (PZ) technology.
The leachate is passed into a patented high quality Microbe Incubated BioReactor (MIBR) where the organic matter is broken down, under anaerobic conditions, in a series of steps to produce methane and carbon dioxide, which can be refined into Organic Natural Gas and used for automobiles, cooking, electricity generation or other thermal applications. The generated gases from the process are stored in tanks to ensure easy management and to prevent air pollution. The added advantage of this solution is that the Hydraulic Retention Time ( HRT ) is as low as 15 to 21 days.
The liquid digestate from post biothene process is fed into BOOMTUBE FP-STAR, which is a patented technology for Wastewater Recovery and Management. Here, the liquid wastewater is bombarded with shortwave frequencies, resulting in removal of electrostatic charge of the dissolved and suspended particles. At this stage, the particles start to collide and agglomerate under the influence of Van der Waals forces, thus separating water from solids. The recovered water can be used back in process after the suspended solids are filtered out with specialized filtration systems.
