ABSTRACT
Various biological treatments produce solid sludge, which needs to be treated further or disposed. The sludge can be incinerated, landfilled or can be used for various construction purposes. The domestic waste can be used for production of ethanol like products. Also various options like vermicomposting and anaerobic treatments are very useful. The methanol synthesis is added advantage of the anaerobic treatment. Aerobic treatments are also very common because of ease and acceptability. Paper waste is generally recycled. It can be recycled for limited number of cycles. Paper waste sludge can be used in concrete with better results. Also biofuel synthesis from the waste papers is reported. Production of ceiling boards, bioelectricity production, and fuel gas generation are some of the cost effective applications of waste papers.
Key words: Reuse, recycle, hypo sludge, strength, enzymatic deinking, bioelectricity.
