Alternate Fuel & Raw Material Facility

Ajay Kumar. Hazardous waste of various type of industries generate hazardous impact on environment the dispose of hazardous waste is very intricate Problem. Lack treatment and disposal facilities cause hazardous wastes (HWs) destruction of municipal landfills and open spaces, raising serious environmental threats. The dispose of hazardous waste through Alternate Fuel and Raw Material Facility gives substitute of fossil fuels as well as reduce the harmful impact on environment.


Introduction
Various types of Industries play an important role in the economy of the country but every industries extract various type of hazardous waste. In the last decades industry, government and the general public have become increasingly aware about hazardous waste the disposal of hazardous waste is huge environmental problems .If it disposal done in proper way it will beneficial for environment. The AFRF is the ideal way of handling and disposal of hazardous waste by this way we can get an option such as reuse, recycle and recovery of energy. Through AFRF Concept hazardous waste can be use as a substitute for fossil fuels or raw material in the cement industries. Pre-Processing hazardous waste fed into the kiln or the pre-calciner. It needs to be noted that certain constituent of the preprocessing hazardous waste should be line with as per specification of ". Central Pollution Control Board (CPCB) in the year 2010, issued "Guidelines on Co processing in/Cement/Power/Steel Industry"

Specifications of hazardous waste for use Energy Recovery
Sr. Does it come in CPCB Guideline Criteria? Will it suitable for AFRF process? Hazardous waste will be adjusted to desired levels as per the possibility and sent to cement industry as an alternative raw material? It will check by Operator (Operator means a person who owns or operates a facility for collection, reception, treatment, storage or disposal of hazardous wastes) laboratory after laboratory Analysis is being decided whether waste have to accept or reject.
Waste transport from the Occupier (Hazardous waste Sources):when hazardous waste shall be collected from the occupier that time waste should be in close and spillage proof containers with labeling (Corrosive, Reactive, Ignitable or Toxic) as per CPCB Guideline and also should be transported in vehicles as per CPCB Guideline along with 6-copy of manifest (as per CPCB Guideline) To be carried by the occupier after taking signature on it form the transporter and the rest of the four copies to be carried by the transporter. Copy 3 (Yellow) To be retained by the operator. Copy 4 (orange) To be return to the transporter by the operator of the facility / recycler after accepting waste.

Copy 5 (green)
To be return by the operator of the facility to State Pollution Control board/Committee after treatment and disposal of the waste. Copy 6 (blue) To be return by the operator of the facility to the occupier after treatment disposal of hazardous materials/wastes.

Preprocessing of waste: -
Before Proper handling and operation of hazardous waste their characteristics should be take into account 1. Ignitability: -ignitability is the characteristic used to the define the waste which may be cause of a fire during transport, storage or disposal 2. Corrosivity: -it characteristic indicated by pH. hazardous waste with high or low pH can react dangerously with other waste and result may be form in corrode, fire , or violent reaction 3. Reactivity:-Unstable waste can generates toxic gases, vapors, or fumes it may be harmful to human health as well as environment 4. Toxicity: -hazardous waste which shows leaching characteristics their improper management leachate percolate in ground water and eventually ground water becomes toxic. Semi solid / tarry waste:-Hazardous waste which are neither liquids nor solid it type of waste found in semisolid state and certain waste are tarry or sticky in nature and some time it is difficult to remove from the drums. Semisolid and terry waste are operated by sigma mixer we use liquid waste with semisolid and tarry waste for mixing and kneading after proper homogenous mixing we convert the semisolid/ tarry waste into liquid form and transfer it to Production storage tank for tanker loading process.

Three types of waste to be processed in AFRF Operation
Note: -whenever mixing and transfer is occurred operation process then compatibility process should be done at all stage of operation otherwise fire, explosion, highly exothermic reaction and Violent Reaction, can be occurs.
