1 Pre-Feasibility Report for Goa Industries Environment Management Association s (GIEMA) Proposed CHWTSDF Facility At Plot No. 5, GIDC, Pissurlem Industrial Area, Pissurlem Post office, Tal. Satari, Dist: North Goa By SMS Envocare Ltd (a group company of SMS Infrastructure Limited).,

2 1. INTRODUCTION 1.1 Introduction Goa has seen a steady growth of industries in the recent years. Government of Goa, while encouraging industrial growth, is also conscious about the Environmental impacts of the industries. Thus, the Governments efforts have been targeted to ensure better compliance to environmental laws and encouraging industries which are low polluting in nature. While the problem of effluent and air pollution can be controlled through readily available & comparatively low cost in-plant treatment technologies, Hazardous waste generated needs treatment and disposal which cannot be undertaken at individual industry level, as this will result in creating pollution hot spots at multiple locations. Thus, highly industrialized states like Maharashtra, Gujarat have installed Common Hazardous Waste Treatment and Disposal Facilities (CHWTSDF) at multiple locations to ensure safe treatment and disposal of wastes. Presently there is no Common Hazardous Waste Treatment Storage and disposal Facility (CHWTSDF) within Goa state. Industries here are required to dispose their hazardous waste in other nearby states which poses following problems : - objections are raised by other states on being used as dumping ground - uneconomical due to high transport cost - hazards during long distance transportation In view of the same, Government of Goa is taking steps to establish Common facilities for treatment and disposal of Hazardous Waste. In order to support the government initiative, Goa Industries Environment Management Association (GIEMA) took active interest and approached Government of Goa to locate a CHWTSDF in Goa. Goa Industrial Development Corporation (GIDC) has allotted requisite plots at Pissurlem Industrial Estate phase I which is a notified Industrial estate. The area of plot is 78,126 sq.m. The proposed facility shall cater the need of entire Goa state s industries. As per EIA Notification S.O.No 1533 dated 14th Sep 2006 and its subsequent amendments the proposed project is falling under Project / Activity 7 (d) Common Hazardous Waste Treatment, Storage and Disposal Facility (CHWTSDFs), Category A (All Integrated facilities having Incineration and landfill or Incineration alone) and requires environmental clearance from Expert Appraisal Committee, at MOEFCC, Delhi. 1.2 Name of the Project Promoters and background: M/s SMS Envocare Ltd.

4 2. BACKGROUND INFORMATION 2.1 Introduction The primary objective of this project is to provide a common Integrated facility for the collection, transportation, treatment and disposal of hazardous waste generated in the state of Goa. GIEMA / GIDC have identified M/s SMS Envocare Limited as service provider for design, finance, construction & operation of the CHWTSDF. 2.2 Brief of project Hazardous Waste disposal is generally done by Incineration (for combustible and highly toxic wastes) and landfilling (with or without pre-treatment). Incineration has benefit of reducing volume and toxicity of wastes. Residues from Incineration are disposed off in landfill. Landfilling is the ultimate disposal and has to be scientifically done to prevent environmental degradation and ground water pollution. This is done by isolating the contaminant pollutants from the environment through pre-treatment and encapsulation. The proposed facility at Pissurlem is an Integrated facility that is it will have facilities for secure landfilling and Incineration designed to meet CPCB standards and will cater to environmentally and economically sound disposal of waste generated in Goa. Aspect Area Capacity Project cost The proposed project finance means shall be as under: Detail 78,126 sq.m. Direct Landfill: 25,000 TPA Incineration: 1.5 Ton/ Hr Rs. 9,000 Lacs Sr No Means Particulars 1 Equity / Owner contribution 30 % of total grants term load 2 Govt grant for TSDF s -- 3 Term loan from Financial institutes / 70 % of (total grants) banks Grand Total Rs. 9, Lacs The site will be operated on BOOT basis. The overall facility shall be so designed in a manner which is reliable and cater for present and for the foreseeable future. The overall objectives of setting up the facility are: To ensure that the environmental impacts due hazardous waste disposal are minimized To ensure that resource conservation is maximized To ensure techno-economic feasibility of the project To enable the TSDF to handle the hazardous wastes in a lawful manner To prevent accumulation of the hazardous wastes at the facility 3

6 2.4 Brief Description of Nature of the Project The proposed project is a Common Hazardous Waste Treatment, Storage, Disposal facility (CHWTSDF) located at Pissurlem Industrial area phase I, Goa, and will cater for safe disposal of hazardous waste for the entire state of Goa Need for the Project and its importance to the country or region There is a growing concern all over the country for the disposal of hazardous wastes generated from anthropogenic sources. The waste generators find it difficult to dispose their hazardous wastes without causing environmental disturbance; very few scientific disposal facilities are available. The Hazardous Waste (Management And Handling) Rules 1989 subsequently revised in 2000, 2003 & 2008, promulgated under the Environment Protection Act 1986 govern the generation, handling, storage, treatment and disposal of Hazardous Wastes. Schedule I and II of the 2008 Rules clearly identify hazardous waste from processes, their characteristics and concentration levels beyond which a waste will be termed as hazardous. As per the Rules, the hazardous wastes need to be disposed off in a secured manner without causing environmental damage. CPCB has published several Guidelines for waste characterization and criteria to choose disposal pathways. Efforts to draw up inventories of Common hazardous waste generated in the country were initiated in year as a follow up to the recommendations of the High Power Committee (HPC) set up under Chairmanship of Shri MGK Menon and Supreme Court Monitoring Committee (SCMC) established by Hon Supreme Court of India. Many reports by CPCB, Delhi have pointed to the need for Common Facilities for Hazardous Waste Disposal in moderately generating HW states like Goa, considering the total quantity of waste generated (estimated 21,925 MTPA from 204 units in ). The primary objective of this project is to provide scientific treatment/ disposal of Hazardous Wastes through Incineration/ common landfill facility to cater to the hazardous wastes generation in Goa state. 2.5 Justification of the Project (Need of the Project and its importance to country and or region) Currently Hazardous Waste TSDF at Goa is being sent to other nearby states for its disposal. There is no CHWTSDF facility presently in the state of Goa. At present there are 18 Industrial estates in Goa state having about 3000 industries as follows: S.no Industrial estates No. of No. of No. of industries industries industries Total in started but yet to start production now closed 1 Tuem Industrial Estate Colvale Industrial Estate Pilerne Industrial Estate Tivim Industrial Estate

7 5 Mapusa Industrial Estate Bicholim Industrial 77 Estate Honda Industrial Estate Pissurlem Industrial 7 Estate Corlim Industrial Estate Madakim Industrial 43 Estate Kundaim Industrial 164 Estate Sancoale Industrial 102 Estate Bethora Industrial 81 Estate Verna Industrial Estate Margao Industrial Estate Kakoda Industrial Estate Cuncolim Industrial 57 Estate Canacona Industrial 26 Estate Total S.no Waste category Estimated quantity 1 Landfillable TPA 2 Incinerable TPA 3 Recyclable TPA Considering the quantity of hazardous waste available from Industries is around 25,000 TPA. Based on this figure the total land available for the Common hazardous Waste Treatment Storage Disposal Facility (CHWTSDF) will suffice for period of about 15 years. As mentioned above currently there is no hazardous waste disposal facility in Goa, hence in order to meet the requirement for treating land fillable, recyclable waste and other types of waste, a Common Hazardous Waste Management Facility is proposed in North Goa district to meet the demand of the state of Goa. 2.6 Required Manpower (Employment generation direct / indirect due to project) Details of the skilled and unskilled manpower for the proposed project during construction and operational phase were given in table below. Sr No Details Construction Operation Remark 1 Management/skilled - 3 Permanent 2 Semiskilled - 9 Permanent 6

8 3 Unskilled On Contract Total Indirect employment during project construction stage will be around 50 The local areas will be benefited by way of generation of employment opportunities. The project creates employment to about 42 persons once the facility comes to the operational stage and for 50 persons during construction stage. Top priority will be given to locals for semi-skilled and unskilled jobs. 7

11 3.3 Details of Alternate sites considered and the basis of selecting the proposed site: Alternate Sites: Presently no alternate sites have been considered. Previously, Government of Goa has notified 1,10,390 sqm of land at Survey number 193/3 for development of CHWTSDF the Environmental clearance for same was obtained in 2008 (from MOEF) (which was valid upto 19/2/2013) and renewed on 21/03/2013 by SEIAA, Goa. However, development of site could not take place due to Public opposition at the site Selection of the Proposed Site The selected site at Pissurlem Industrial estate is based on CPCB Knock-out criteria that are based on certain parameters such as characteristics of land, geology, hydro-geology, ground water conditions and ecological considerations etc. 3.4 Size or Magnitude of Operation: The proposed project will be set-up on 78,126 sq.mtr (over 14 Acres) land at Pissurlem GIDC. The capacity of the proposed site shall be as follows: Sr. No Description Quantity, TPA 1 Direct Landfill 25,000 2 Incineration 1.5 tons/hr 3.5 Project Description with Process Details Common Hazardous Waste Treatment Storage Disposal Facility (CHWTSDF) is a facility where hazardous waste are collected, transported & scientifically disposed off from small/ medium / large scale industries. Collected wastes are stored as per the guidelines of Maximum quantity of 10MT or a minimum period of three months whichever is applicable and taken to the facility for safe and scientific disposal. Common Hazardous Waste Treatment Storage Disposal Facility (CHWTSDF) is meant for final disposal of hazardous waste generated from various production activities. The proper functioning and implementation of necessary treatment schemes installed at this site will reduce the environmental risks expected to be generated from malfunctioning and mismanagement of disposal of hazardous waste. The entire facility will be divided into the following phases: Phase I: Development of weighing scale Construction of temporary storage Laboratory Pre-treatment Development of 1st Cell of secured disposal facility [landfill] Leachate treatment plant [LTP] Phase-II: 10

12 Second Stream of Incinerator or plasma based technology with Air Pollution Control System for treatment & disposal of Incinerable waste as per the HW Rules 2008 & amendments. 3.6 General Features of the proposed CHWTSDF The following are the general features of the proposed CHWTSDF plant. Secured Land Fill (SLF) Facility: Capacity: MT / Annum Period: 15 Years Area Required: 8 Hectares As per CPCB Guidelines, Secured landfills may be designed to accept the following hazardous waste: Wastes which do not exceed biodegradable organics more than 5 % and total Organic content more than 20% and wastes which do not have calorific values more than 2500 Kcal/kg. Sludge from effluent treatment plants Air pollution control dust and sludge Incineration residues Organic chemical residues amenable to stabilization Oil refinery waste and sludge amenable to stabilization Pesticide bearing waste amenable to stabilization Waste from paints and coating industries amenable to stabilization Waste from pharmaceutical industries amenable to stabilization. The waste maybe either sent for landfilling directly or after necessary pretreatment. Thus proposed facility can be broadly divided into following sections Waste Receipt, Characterization and storage Secured Land Filling Landfill After Treatment Waste Receipt Characterization and storage: Treatment of chemical waste and its disposal is mainly accomplished through three processes viz. physico-chemical, Incineration and secure landfill. But in this case we are not going in for Incineration facility in phase I. Prior to taking up effective treatment it is necessary to collect, segregate and store adequate quantity of waste in most scientific manner through safe transportation system and storage facility. The storage facility shall therefore comprise of temporary storage and permanent storage for separate storage of treatable and intractable / incompatible waste. The requirement / selection of proper treatment shall be met through appropriate laboratory analysis / equipment which enable to select appropriate treatment viz. direct disposal to landfill without any preliminary treatment or giving pretreatment before doing the landfill. The provision for secondary treatment for waste water treatment etc. shall also be made to meet desired disposal standard set for liquid discharge by regulatory authority. 11

13 3.6.2 Details of Secured Land Filling: The Construction of Secured Land Fill site shall consist of following steps:- A. Site Investigation: For detailed engineering design, a detailed investigation program shall be carried out which will comprise of, a) Subsoil Investigation b) Ground Water c) Topographical Investigation d) Hydrological Investigation e) Geological Investigation and Seismic Investigation B. Study of Characterization and Quantification of Waste: A comprehensive survey of waste generators, its quantity, and its characteristics has been carried out. C. Land Area Calculation: Considering the quantity of hazardous waste available from Industries is around TPA. Based on this figure the total land requirement for development of Common hazardous Waste Treatment Storage Disposal Facility (CHWTSDF) for period of about 25 years has been calculated to be about 1,50,000 Sq.mt. (i.e. Approx. 15 Hectares). In this estimation, the growth rate has been taken as 5 %, the specific gravity of the waste as 1.2, the height of the landfill as 9.5 meter and inclination 1:2. It is estimated that the available land will suffice the needs of Goan industry for next 15 years. D. Planning and Detailed Engineering Design: After studying all site investigation result and EIA results, SMSEL will be able to finalize the master plan. Plan shall comprise of following component Construction of water supply, wastewater / sewage disposal system, surface water drainage system, treatment facility for waste water & leachate etc. Secure Landfill with bottom liner, side liner as per the requirement of norms, with leachate collection system. Intermediate storage facility with the entire necessary requirement like liner system as well as leachate collection system. Solidification /Stabilization plant including crusher, trolleys hopper and mixer. The weighbridges to ensure the quantity of wastes received at the facility. Analytical Laboratory for segregation of waste before treatment. An administration office to manage the day to day operation and management of the facility and also for maintaining the records of waste management Entry gates guarded by the security to prevent the unauthorized movement of waste vehicles, animals and humans. Approach roads for easy access and transportation of waste within the facility. Monitoring well, in the upstream and downstream of the facility to assess and monitor the ground water quality in and around the facility. 12

14 Wheel washing station to facilitate the cleaning of vehicles to avoid the spillage and contamination of roads within the facility and outside facility. Green belt development: It is proposed to be developed all along the boundary of CHWTSDF for reducing the soil erosion, suppress dust generation and enhancing the aesthetic value of the area. E. Phase of operation: A detailed chemical & physical analysis of a representative sample of waste will be conducted before shipment of waste. The purpose of the full characterization before shipment is to satisfy the following requirements. Determine if the waste is acceptable for receipt at the facility in terms of (a) the facility s permit and (b) the capability of the facility to treat or dispose of the waste. Identify the inherent hazards of the waste so that appropriate precautions can be taken during its handling and storage at the facility to prevent incidents. Determine the physical characteristics and chemical constituents of the waste to allow selection of effective waste processing and disposal methods. Select the verification parameters to be tested upon arrival at the facility. These parameters would ensure that each shipment of waste is the same type as the fully characterized waste. Select any treatability parameters to be tested that could vary so as to influence how waste processing would be programmed. Develop an estimate of the cost of treatment of disposal Waste Receiving: Waste shipment is done by the GSPCB authorized transport vehicle as per the Hazardous waste Transportation Rule from generators to the common facility. After arriving of the shipment at the gate following steps shall be followed. Check the pre shipment analysis has already completed and the shipment scheduled. The truck is weighed. Representative sample is collected for testing & verification of parameters. The laboratory analysis a portion or verification. The truck is directed to an unloading area. Unloading area can be temporary hazardous waste storage area, storage area for stabilization of waste or direct to secure land filling. After unloading truck is directed to wheel wash area. The truck is then reweighed before it leaves the facility Waste Storage and Preparation: Main objective of storage and preparation are: Store the waste safely before introducing as feed into the system of unit treatment and disposal process. Provide adequate accumulation time during periods when treatment and disposal process system are out of service. Facilitate mixing, blending and repacking of waste as deemed necessary. At the storage & preparation stage following safety considerations is taken: Fire prevention and protection & adequate waste supply for this. Water sprinklers. 13

15 Systematic runoff collection and drainage system. Adequate separate storage area for incompatible waste Waste Treatment: After maintaining the waste in storage the treatment schedule is developed from the laboratory analysis report. The waste is treated & head to the final disposal facility. The flow diagram for the same is shown in Figure Residual Management Each waste treatment process produces wastewater effluents which are required to treat further. For this residuals proponent have proposed to take the Leachate water or wheel wash effluent shall be taken to effluent treatment plant for proper treatment. Figure I Process Flow Diagram for Hazardous waste Management- Phase I Secured Landfill Cell Secured landfill is the part of waste management facility. This place is final graveyard for the hazardous wastes. This secure landfill is prepared as cells. These cells have bottom, side liners and top liners. The impermeability and reactivity of these liners is of prime importance. Once the bottom and side liners are complete, waste is dumped. On complete filling of waste the top liners are placed and packed. In other words its encapsulation of waste. Leachate collection system is provided in cell in order to collect leachate in well for the further treatment and disposal. The CHWTSDF will consist of number of such Secured landfill cells, having a life much above 20 years (total about lac tons). The additional life will take care of the projected growth rate of waste generation and receipt, which has been taken at 5 % in the line with the growth rate of industries of the region Construction Features The construction of landfill and development phase requires proper planning and proper selection of the earthwork/lining material. The containment system of landfill is proposed with double liner system with a view to avoid the leachate infiltration into the ground.

Super fund for any unforeseen event Incineration Plant For Organic And Toxic Hazardous Waste Destruction Introduction Incineration process is adopted for the destruction of toxic and organic hazardous waste received at the site. The total numbers of industrial estates in Goa are 18 and approximately 1865 industries are present in 18 industrial estates. There are different kind of industries like Pharmaceutical industries, Pesticides industries, Distilleries, Cosmetics, Tyre industries and Industrial lubricating oil, automotive lubricants & solvents which are generating large quantum of incinerable waste. The total quantum of Incinerable waste is TPA. At present Goa is not having any facility or technology to treat and handle incinerable waste. As Goa is not having any treatment facility so they are transporting their incinerable waste to different states and transportation of hazardous waste is an unsafe method. In the second phase of our Setting up of Common Hazardous Waste Treatment, Storage & Disposal Facility at Pissurlem Industrial Area, Goa we have proposed an incinerator facility at site. Incinerator facility will handle and treat the incinerable waste from all 18 industries estates. In incineration process rotary kiln is provided as primary combustion chamber and is operated in presence of excess air where minimum Deg C The temperature is maintained by controlling excess air and by support of fuel such as LDO through temperature controller. The flue gas from the primary combustion chamber is taken to post combustion chamber where flue gas temperature is elevated to Deg C provided minimum 2 seconds retention time to achieve destruction of toxic organic compounds. Bottom ash is collected in solid form from the bottom of the furnace. Flue gas from the secondary combustion chamber is then treated in Air Pollution Control System to achieve the flue gas disposal norms before it is vented to atmosphere. Plant Capacity: Solid / Semisolid / Liquid waste 1500 kg/hr Average CV of waste 4000 Kcal/kg Thermal capacity 6 Million Kcal / hr Average characteristic of waste. 17

Ash left out in Rotary Furnace falls at the bottom hopper of the secondary furnace from where it is discharged through ash removal system. Ash will be collected in underground RCC tank where it is allowed to cool down. Secondary Chamber Hot flue gas from the rotary furnace shall be fed to the secondary chamber. Secondary chamber shall be stationary vertical brick lined furnace.. Here, flue gas temperature is raised to 1200 C using an oil burner. This oil burner is also provided with burner management system to control temperature, oil to fuel ratio and flame failure device. Here 19

21 flue gas is given retention time of more than 2 seconds to ensure complete destruction and removal efficiency of organic constituents. Secondary furnace shall be insulated from outside for reducing surface heat loss. Hazardous waste destruction shall be carried out in rotary kiln furnace followed by post combustion chamber. 3.7 Air Pollution Control Section Five stage flue gas cleaning system is provided to meet the final emission limit. Stage 1: Gas Quencher Gas quencher shall be installed immediately after secondary combustion chamber. It shall be designed to take gas inlet temperature of 1200 C. Here gas shall be cooled down in circulation of water mixed with aqueous waste (scrubber bleed liquor / effluent) by evaporation of the water part. Gas is cooled down to C in spray tower by evaporation of water. Stage 2: Bag Filter Saturated gas from gas quencher is fed to reverse pulse jet type bag filter system. Before bag filter activated carbon is injected into gas stream for adsorption of any VOCs left out on surface of activated carbon. Bag filter is provided with SS casing and internals with Teflon coated glass fiber bags which can withstand temperature of gas up to C on continuous basis. Bag filter is provided with 0.8 to 1 M/Min Air to cloth ratio. Bag filter is provided with complete assembly of cages, venturies and compressed air injectors with sequential control systems. Collected solids from the bottom of bag filter are removed through air sealed rotary valve. Bag filter is also provided with heater system to maintain min C inside bag house to avoid condensation of moisture on the bag. Stage 3: Ventury Scrubber From Bag filter clean gas is passed through ventury scrubber where gas is quenched to saturation temperature along with pollutant gases such as HCl and SO2 is absorbed in continuous circulation of alkaline scrubber solution. Free alkalinity in the scrubber solution is maintained by continuous addition of caustic lye in the scrubber liquor. Part of the scrubber solution is continuously bled off from the system. Suspended solids are filtered in filter press and then bleed liquor is sent outside for treatment in effluent treatment plant. Stage 4: Polishing Scrubber Cooled and saturated gas at 78 0 C shall be taken to polishing scrubber. In polishing scrubber provided polishing scrubbing for the removal of traces of pollutant gases. In the second stage of polishing scrubber gas is cooled down to 50 0 C by direct cooling of gases through circulating liquor through cooling tower. Due to cooling of gas evaporated waste water in the system is condensed into liquid stream. Additional scrubber liquor thus generated is sent to effluent treatment plant for the further treatment. ID Fan A centrifugal fan is provided to maintain negative draft in the system and to overcome pressure drop in the entire system. Negative pressure in rotary kiln is controlled automatically by controlling speed of the fan through inverter drive. Stage 5: Stack A rubber lined stack shall be provided after the scrubber system with flue gas sampling port, platform, ladder with safety ring. Emergency Stack The emergency stack is located on top of the secondary chamber. It is pneumatically operated. In case of system stoppage, solid waste present in the Incinerator will continue to 20

22 generate gas due to heat. The flue gas generated during this period needs to be vented out. This is achieved by automatic opening of emergency flap. Emergency Overhead Tank Though emergency stack vents the gas to atmosphere during power failure, additional safety system consisting of overhead tank is provided to quench the residual flue gas present in the quencher. This can cause damage to downstream equipment because of overheating. In order to protect the same, water from emergency overhead tank floods the quencher allowing cooling of flue gas. Operating standard as per CPCB Guidelines Emission standards Metals: While operating properly at rated capacity, the system shall have an emission rate from the discharge of stack to atmosphere less than or equal to Metals: Emission Limit (mg/nm3) Cd+Th (& its compounds) 0.05 Hg (& its compounds) 0.05 Sb+As+Pb+Cr+Cu+Mn+Ni+V (& it s compounds) 0.5 Note: All values above shall be corrected to 10% oxygen on dry volume basis.
