28. How does Bio Drying Work? © GJ ECO POWER PVT LTD 2016. All rights reserved. 28 The existing naturally occurring bacteria in the waste is used to generate heat, which then evaporates the moisture and dries the waste to just below 30% moisture level Once the correct moisture level is reached, the heat is allowed to increase to the point where the bacteria can no longer survive. The bacteria dies, the waste is now sanitised and Safe for the staff to handle and move.

39. Flue Gas and Air Emissions Kochi Waste to Energy plant does not rely only on cleaning the flue gas but a combination of things. Good emission values are achieved by a combination of: fuel content control; (Waste reception and Bio drying areas) fuel preparation quality; (MRF Material Recovery Facility) fuel feed control; (Blending bunker system) gasifier design and operation – to break down hydrocarbons combustion chamber design – to ensure control of CO and maximise burn-out of heavy hydrocarbons and particulate matter; boiler design – to control dioxin and furan formation by preventing de Novo synthesis; flue gas cleaning measures;

41. Item 1 – Urea Injection Item 2 – Active Carbon Injection Item 3 – Hydrated Lime Injection To control emission of NO x gases into the atmosphere a Selective Non-Catalytic Reduction (SNCR) injection system is installed. The SNCR system injects a urea solution into the gas stream, which breaks down to form ammonia, and reacts with the NO x gases in the combustion gas stream to form nitrogen, carbon dioxide, and water. The injection of urea into the gas stream occur between 760°C and 1090°C and is injected into the flue gas outlet from the primary combustion chamber. Active carbon is used as an absorption material to ensure the capture of dioxins, volatile organic compounds (VOCs), furans and heavy metals vapours such as. (cadmium, thallium, mercury, tin, arsenic, lead, chromium, copper, cobalt, manganese, nickel, vanadium etc.);   Lime is used to control the levels of acidity and aid the capture of Hydrogen Chloride (HCI) Sulphur Dioxide ( SOx ) and Hydrogen Fluoride ( HF); Item 4 - Bag House Filter   Item 5 - DCS Downstream of the injection of Active Carbon and Lime. The fabric filter captures fine particulates, heavy metals, dioxins and furans. Which cannot pass through the filter.   APC and Fly ash from both the Boiler and the Bag House filter is remo0ved by a rotary valve and conveyed to a storage receiver.   The Continuous Emission Monitoring Unit (CEM) continually sends a signal to the Distribution Control System (DCS)   If the flue gas is outside of the set parameters, the DCS will increase/reduce the injection of the various flue gas cleaning chemicals. If this fails to correct the problem, the main Control System will complete a controlled shutdown of the plant.   Emission Control Methods

42. Water Water Requirement for power generation. Cooling water make up - 1.80 MLD Boiler Water make up - 0.15 MLD Service Water make up - 0.04 MLD Raw Water Requirement – 2 MLD Source of water A. Surface water : Kadambrayar and Chitrapuzha B. Ground water : Open wells, Borewells and Water Conservation area (1.4 Acres) C. Rain water Harvesting : Roof space (38000 sq. mtr ) and underground

43. Rain water harvesting Modular Rain Water Harvesting Storage Tank Storage capacity: 3000 KL Rain water harvesting: 38024 Sqm x 50=1901200 Lts = 1901 KL Rain Water Harvesting Rain water harvesting is designed to reduce utilization of precious water resource. Rain water run off from plant roof (38000 sq. mtr ) will be captured and stored for plant requirements. Excess rain water is diverted thru storm water drain to water conservation area (1.45 Acre). Strom Water drains are designed and routed to avoid contamination with Leachate or other Effluents

44. Leachate treatment & reuse Leachate is captured at the points where it is released by the incoming waste & delivery trucks (estimated at not more than 106.2m 3 per day) Technology chosen is proven with operating sites globally After the Leachate has passed trough an aeration tank, a proportion (10%) of the leachate is then sprayed on to new waste as it goes to the Bio Drying area The remaining leachate is passed through a number of treatment filtration processes. 90% or an average of 86m 3 per day of the processed leachate is converted to fresh water and reused on the site

45. 45 Project is located in Brahamapuram, Vadavukode-Puthencruz Panchayat, Kanayannur Taluk, Ernakulam District The Project location Coordinates 9°59'34.83"N, 76°22'6.46"E Project site is within the continuum of the Ambalamugal industrial cluster and adjacent to Brahmapuram Diesel Power Plant KMC has earmarked 9.66 hectares next to their existing waste facility in Brahmapuram Waste to Energy plant is planned in an area of 8 Ha [~ 20 acres], PROJECT LOCATION
