RECYCLING OF PAPER WASTE IN PLASTER COMPOSITE MIXTURE

RECYCLING OF PAPER WASTE IN PLASTER COMPOSITE MIXTURE.

PAPER Is a thin material mainly used for writing upon, printing upon or for packaging. PAPER WASTE Is the term used for the paper that is no more helpful for intended use. Paper waste is generated from different sources like offices, Institutions, Industries, household activities and many more. Effects of paper discarded to landfill or sent back to industry. PAPER RECYCLING Paper recycling is the process of recovering waste paper and remaking it into further useful products..

PROBLEM STATEMENT Paper when not left for any intended use is usually discarded, which contributes to the waste generation and pollution. The discarded paper either cause load in the landfills or sent back to the industries. Most of the times, the solution found to reduce paper waste is to burn it, which is a great source of air pollution. Paper contains many toxins that leak into the soil from open and covered landfills and into soil, where it causes ecological damage. In such case we can only do Recycling of paper to saves oil and energy and cuts air and water pollution. By keeping this approach we are going to recycle paper waste and use it as a plaster material.

AIMS AND OBJECTIVES. Calculating the waste generation rate (Ibn-e-Sina block) and characterizing the types of paper wastes. Designing and installing the bench scale setup for the production of plaster mortar. Evaluating the performance of bench scale system for paper recycling. Performing different tests to evaluate the strength of plaster mortar.

METHODOLOGY. Waste generation Rate Waste generation rate is calculated by collecting samples from different offices in kg/capita/semester and the waste is characterized. Table below shows some of the calculated waste generation rates.

2. Waste Collection Waste paper is collected from approximately every office of ibn-e- sina block . Waste paper type include Copy papers, A4 papers, and cardboard . 3. Identification of mortar ingredients and processes Mortar ingredients are identified like sand, cement, paper &purchasing..

4. Mortar making processes Ratio 1:1.5 Shredding and mixing by Hand Paper is soaked in water for 48hrs, shredded and mixed in other mortar ingredients manually II . Shredding and mixing by machine Paper is shredded in Machine and mixed with other mortar products in mortar mixer..

III. Shredding by machine and mixing by hand Paper is shredded in Machine and mixed with other mortar products in mortar mixer. By each method molds are prepared, and placed for 24 hrs. to dry..

5. Testing Compressive strength Prepared molds were placed in water for 7, 14 , 21 days and tested on respective days..
