The first important step is to understand what the different types of waste that need to be managed are. Data on quantities that are generated, their category number as classified by Schedule I of the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016, properties with an MSDS if available, method of storage, etc. is collected.
In order for waste to be accepted at our facility, it is paramount that the waste generator has authorisation from KSPCB to generate and dispose of the waste to a common incineration facility. It is also important that Haat has authorisation for the same categories of waste which are to be disposed of by incineration by the waste generator. If the category numbers do not match, then waste cannot be accepted. The only exception would be if the waste generator has a one-time authorisation from the KSPCB to dispose of the waste to a common facility.
Pricing is dependent on type of waste, quantity generated, distance from facility and several other factors. Before acceptance of waste at our facility, a PO is mandatory. Clients who wish to have long term arrangements are encouraged to enter into an agreement with Haat as they then get priority over other clients.
A monthly transport schedule is prepared and discussed with clients to fix up dates of transport as per their convenience. The vehicle undergoes daily checks to ensure key elements required for hazardous waste transport are met such as functionality of lights, validity of certificates, GPS signals, spark arrestor, awareness and training of driver and loading staff, route plan and emergency response.
Waste received is unloaded into empty drums, labelled and sent to the waste storage room. It is ensured that reactive wastes are not mixed or kept next to each other. The process of waste receipt and incineration is carefully managed to ensure FIFO. The room is well ventilated with natural air draught exhausts to prevent build-up of VOCs. Adequate protection against rain water and prevention of seepage into the ground is ensured. A series of powder based fire extinguishers which automatically dispense fire retarding material beyond a certain temperature are installed for immediate action day or night. Entry of people is regulated and a dedicated emergency exit is provided.
In order to ensure a consistent heat value of material being fed into the incinerator, wastes are packed by mixing high and lower calorific value types in bags or boxes. The packing activity is considered a high risk task and operators are instructed on safe methods. Substantial hazop studies have been done to try and eliminate risks where possible after which risk management plans are in place to ensure safety of staff.
