Industries produce various types of waste which includes biodegradable, non-biodegradable, toxic, and radioactive, out of which 10 to 15 % are non-biodegradable and hazardous waste. Examples are plastic, glass objects, silver foil, gypsum etc. The increase Industrial wastes are categorized into two types:
It is estimated that 50 million tons of E-waste are discarded every year. And only 15-20% of this waste is recycled. E waste includes: Cathode Ray tubes, Printed circuit boards, Computer wires, Plastics from body of the devices etc. E wastes are non-biodegradable and toxic. E waste contains hazardous components like:
At present, contaminated industrial waste is contaminated, and the uncontrolled discharge has become a major issue. Heavy metals are non-biodegradable, persistent and continue to exceed the permissible concentration of very large compounds in cells and cause cellular toxicity. The only way to think of them is to eliminate them is immobilizing. For this purpose, there are predefined traditional methods of chemistry, oxidation, reduction, filtration, electrochemical, evaporation, concentration and exchange of ion exchange resins. These techniques require more energy consumption, especially reducing solutions.
Here, microbial biomass provides a financial opportunity to eliminate heavy metals through the biosorption phenomenon. Some reactive groups, such as carbohydrates, congenital, imidazole, phosphate, sulfhydryl, sulfate and hydroxyl groups are metal sequestrants on their cell surface due to lack of biomass or death. This process can be achieved economically by using biomass from biomass from industry. Using a batch or direct drive without biomass is a constant process for removing heavy metals that can develop into a fixed bed reactor. The additional biosorption probability of biomass is improved by various physical and chemical treatments. The diversity of microbial biomass and its potential availability of metal bonding make it an economical and sustainable choice for developing a waste water treatment process for removing and recovering heavy metals.
Solidification is the physical stabilization process aimed to improve the engineering parameters of the materials, such as compressive strength, bearing capacity, wear resistance and erosion prevention strength, and permeability so that the happen of release of contaminants from solidified blocks in a disposal site can be decreased. Binders such as cement, pozzlonas, and thermoplastics are used to immobilize contaminants in sludge. The extent of stabilization is tested using leachability analysis.
