Impacts of solid waste including bottom ash, fly ash, scrubber water, and various miscellaneous waste streams and other residues like such as lime and activated carbon, themselves with condensedor absorbed contaminants • Initial sorting of municipal-solid to remove stream of large items unsuitable for burning (such as whole refrigerators, gas stoves, and auto batteries. • Knowledge of the intrinsic properties of the material, including the physical, chemical, and leaching properties by the incinerator operator. • Solid waste to be handled managed and disposed according to the Environmental Management and Coordination (Waste Management) Regulations 2006. • Abinya Solutions Limited to contract a NEMA licensed waste collection company to be collecting all solid waste from the apartments. • Solid waste to be collected daily from the apartments for disposal at NEMA licensed disposal sites only. • Only NEMA licensed vehicles to be used to collect and transport waste from the facility. • Waste handling bins to be provided, each bin should have a lid which should always be covered. • Colour code to be used to distinguish waste bins of different waste; • Waste to be sorted at source. • There should be no scattering of waste during transportation to and from disposal site. Ash handling at site • The ash be contained at all times both inside and outside the facility. • Use of water to quench the ash, simultaneously reducing dust generation and minimizing the possibility of ash-dust inhalation or ingestion by workers. • Enclosed ash-handling systems throughout the incinerator. Ash disposal • Fly ash residues are to be transported and disposed of only after it has been solidified in the incineration plant. • Ash be handled and disposed in a secure hazardous-waste landfill that is designed to ensure that there will be no groundwater pollution. • Regular testing of ash to determine its toxicity. Scrubber waste disposal • Wet-scrubber wastewater be discharged to on-site wastewater-treatment system. Operational inefficiency leading to GHG emissions • Screening incoming wastes at the plant to reduce incineration of wastes (such as batteries) that are non-combustible and are 4216 4216 Possible Impacts Mitigation Measures likely to produce pollutants when burned. • Certification procedure for incinerator control-room operators. • Emissions be reduced by modifying operating characteristics such as furnace temperature, air-injection rate, flue-gas temperature, reagent type, and injection rate, and be selecting optimal combustor designs and emission-control technologies. • Use and continued calibration and maintenance of continuous monitors of emissions and process characteristics provide real-time feedback and facilitate maintenance of optimal operating conditions at all times by incineration operators. • Computerized continuous emission monitors CO, O2, SOx, NOx, and HCl. • Survey furnace emission-control devices equipment regularly to ensure that they continue to be operative and properly sealed and insulated.
