Title of Invention	A METHOD FOR TREATMENT OF SOLID MUNICIPAL WASTE TO OBTAIN PULP FOR MAKING PAPER
Abstract	The production of the pulp from compostable matter of the Municipal Solid Waste (MSW) is carried out first by cooking the solid waste with Sodium bicarbonate for one hour. The solid mass is then filtered and hammered vigorously for one hour and washed. It is then mixed with the above filtrate and water, boiled to 90 ° c and then hot mixture of Sodium Hydroxide and Sodium Sulphide is added to the solid mass. This mixture is heated for two hours between the temperature 85° C to 90° C. Again it is filtered and washed. Finally it is bleached with Sodium Hypochlorite followed by H2O2 solution to get white pulpy mass.

Key Words : MSW, NaOH, Pulp, Sodium hypochlorite , H202 Description of the invention; All human activities inevitably produce high quantities of waste. Rapid industrialization and urbanization has resulted into generation of large quantities of solid waste. In the desired production of goods and services, the quantity of waste generated is so high that, the natural process of recycling and degradation itself is insufficient.

Billions of tons of solid waste is generated annually, of which millions of tons remains untreated causing massive environmental pollution. Central Pollution Control Board .India reports that India generates approximately one lakh tones of MSW per day. Due to no segregation followed by improper treatments and disposal methods coupled with pressure of inadequate resources, urban local bodies are experiencing the tough time in MSWM system. Every year millions of rupees are drawn from national exchequer to deal with the MSW without any concrete outputs. The strategies involved in MSWM with respect to economics are garbaged by the implementing authorities. Though the government is spending huge amounts on MSWM, the backup system is lagging in pushing up the clean environment drive. Thus the strategies and planning in MSWM system would simply will not serve the purpose, but it is the will and thought of ownness that will bring about the sustainable developments in the process of MSWM system. The present work, which is on the production of pulp from Municipal Solid Waste, will not only tackle with the MSW but will also add to economy. The municipal Solid waste was collected and segregated to remove the inert materials such as glass, plastic, rubber, metal, debris etc. The remaining portion or the compostable matter, the typical composition is illustrated in the table 1, was dried in the oven at 105 ° c for one hour. The crispy material is then pulverized to fine particle size. Of this pulverized material 100 grams is taken in the beaker with 500 ml of tap water, boiled and 2 grams of Sodium bicarbonate is added slowly to the mass. The mixture is then cooked for one hour with continuous stirring. The volume of the mixture is maintained to 500ml with frequent addition of the water. It is then filtered (this filtrate is reused in the second step reaction) and hammered vigorously for one hour. This solid mass is then washed and transferred to reaction beaker along with filtrate and made up to 500 ml with tap water. It is then heated to 90 0 c. The hot aqueous mixture of Sodium Hydroxide 20 grams and Sodium Sulphide 2 grams in a tap water of 100 ml is added slowly to the hot mass in a reaction beaker. The entire mixture is heated and stirred continuously between the temperature 85° C to 90° C for two hours. It is then filtered, washed and bleached with 20 ml 5% Sodium hypochlorite solution followed by 5 ml of 20% hydrogen peroxide solution. The white pulp is them removed by filtration, washed, dried and weighed. Municipal Solid waste being the good source of the Cellulosic fiber, the application of the pulp recovery from the biological component of Municipal Solid Waste will be a good environmental economics. Thorough experimentation was carried to reach the desired final product as in fig. 3. The fig 1 and fig 2 are the initial experimentation results. In most of the pulping processes Sodium Carbonate is used as a make up chemical. On the contrary in this process Sodium bicarbonate was successfully used as an initial cooking chemical to loosen the fibres and accelerate the next step of reaction thereby reducing the requirement of the caustic.

On an average 37% recovery of the pulp was observed from the biological fraction of MSW collected from the different sites. Environmental Aspects The recovery of the pulp from the MSW can have good environmental and economical balance. The recovery of the pulp from MSW will add to the economics simultaneously reducing the tons of the MSW to the pulp.

On an average about 37 % of the pulp is produced from biological matter in MSW. The production of pulp from MSW can be economical and eco-friendly. It will reduce the burden on the forests for pulp production, thereby playing important role in conservation of environment. Management of MSW is a global issue. The huge quantities and the versatility in the composition of the MSW receive challenges in collection, segregation, transportation treatments and disposal methods.
