This document describes an experimental investigation into manufacturing bricks using sludge and paper pulp residue. Sludge from wastewater treatment and residue from paper pulp production are industrial wastes that require proper disposal. The study aims to incorporate these wastes into brick production as partial replacements for traditional materials like clay. Bricks are made with mixtures containing fly ash, lime, quarry dust, gypsum, and varying percentages of sludge and pulp residue from 5-15%. The resulting bricks are tested to determine optimum waste content without burning. Using industrial wastes could provide a sustainable building material while reducing pollution from waste disposal.
Indian construction industry is growing at a rate of 9.2% as against the world average of 5.5%.
Construction by nature is not an eco-friendly activity. Construction, renovation and demolition activities lead to the formation of waste.
Growth in construction activities generates construction waste which is fast becoming a serious environmental problem with deadly
consequences. Most of the construction and demolition, waste in our country are not recycled but end up in landfills occupying valuable
land.
The promotion of environmental management and the mission of sustainable development have exerted the pressure demanding for
the adoption of proper methods to protect the environment across all industries including construction.
Construction waste recycling reduces the demand up on new resources. Cuts down the cost and effort of transport and production. Use
waste which would otherwise be lost to land fill sites.

To Study Characterstic Behaviour of Recycled Concrete Aggregateijtsrd
Near about 30 of concrete is produce by concrete industry and it is calculated that in a year 165 million tonnes of concrete is used. Hence, to produce other total sources that are based on waste products, there are many significant incentives. Recycling products are used to produce aggregate Martials for unbound fills, pipe bidding and sub base as the RCA "Recycled Concrete Aggregate" or RCA is not suitable for concrete that is ready to mix because it is blended with another products. Many sites did trials with RCA that mix with ready mix concrete but it was not useful choice. Utilities organizations produce brick, containing stone, clay, Trench arising, asphalt, and concrete but that could be merged in low power concrete which were a cost effective trench product. IN trench reinstatement from RCA formed concrete is used that has 4mm fines and in formed concrete, it has ability to use burner bottom ash. BS 8500 concrete improved the potential for recycling as BS EN 12620. Presently recycled products for concrete is not available but it is a hope that they will be used in future.

Experimental Study of Partial Replacement of Fine Aggregate with Waste Materi...IJRES Journal
The utilization of industrial and agricultural waste produced by industrial process has been the focus of waste reduction research for economical, environmental and technical reasons. This is because over 300 million tones of industrial waste are being produced per annual by agricultural and industrial process in India. The problem arising from continuous technological and industrial development is the disposal of waste material. If some of the waste materials are found suitable in concrete making not only cost of construction can be cut down, but also safe disposal of waste material can be achieved. The cement of high strength concrete is generally high which often leads to higher shrinkage and greater evaluation of neat of hydration besides increase in cost. A partial substitution of cement by an industrial waste is not only economical but also improves the properties of fresh and hardened concrete and enhance the durability characteristics besides the safe disposal of waste material thereby protecting the environment form pollution This paper deals with partial replacement of fine aggregate with the industrial waste from China Clay industries. The compressive strength, split tensile strength and flexural strength of conventional concrete and fine aggregate replaced concrete are compared and the results are tabulated.
An experimental laboratory study on utilisation of e waste as a partial repla...eSAT Journals
Abstract
The Growth in the Electronics sector has been rapid and this rapid growth is due to continuous upgradation of technology and introduction of new technologies to the market. This has led to one of the fastest growing solid waste in the world, simply called as E-waste. India is the 5th highest e-waste producer in the world. The rapid increase in the construction activity in India, has resulted in huge demand for the aggregates to be used in the concrete. This has led to depletion of natural resources and adverse changes in the environment. This rapid development in the infrastructure sector has led to shortage of natural sand. This paper outlines the experimental work carried for utilisation of e-waste as a partial replacement for the fine aggregates. Strength tests and durability tests are conducted on hardened concrete. Results show that the partial use of E- waste as fine aggregates results in much higher workable and less dense concrete. This study gives an Economic, environment friendly and efficient disposal method for E-waste to be used as a partial replacement to the fine aggregates in concrete.

Effective Utilisation of Waste Glass in ConcreteIJERA Editor
Glass is a widely used product throughout the world; it is versatile, durable and reliable. The uses of glass
ranges drastically, therefore waste glass is discarded, stockpiled or land filled. About million tons of waste glass
is generated and around large percent of this glass is disposed of in landfills. This pattern has influenced
environmental organizations to pressure the professional community to lower the amount of glass being
discarded as well as find use to the non-recycled glass in new applications. In relation, the recycling of waste
glass as a component in concrete gives waste glass a sustainable alternative to land filling and therefore makes it
economically viable.The proposed study of utilising waste glass powder(GLP) in concrete as partial replacement
of cement as well as the use of crushed glass particles(CGP) retained on 1.18mm & 2.36mm IS sieve as a partial
replacement to sand, which offers important benefits related to strength of concrete as well as it is eco-friendly.
Recycling of mixed-colour waste glass possesses major problems for municipalities, and this problem can be
greatly eliminated by re-using waste glass as sand/cement replacement in concrete. Moreover, re-using waste
materials in construction can reduce the demand on the sources of primary materials.In this project the attempts
have been made to partially replace the cement as well as sand by waste glass powder and crushed glass
particles with equal combination by 5% interval up to 20% replacement and observe its effect on the strength of
concrete after 7 days and 28 days of curing.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
