DURIAN PEELING AS SUBSTITUTE MATERIAL FOR HANDMADE PAPER BACKGROUND OF THE STUDY: Paper is a fundamental part of most of the society: worldwide‚ a total of approximately 300 million tons of paper are produced each day‚ and approximately 90 % of this paper is produced from mature pulp wood. In addition‚ the demand for paper is expected to increase. Today the finest of papers are produced all over the world. But one dismaying fact is that millions of trees are used to make paper.Trees do so much

The Identification and Production of Materials 1. Fossil fuels provide both energy and raw materials such as ethylene‚ for the production of other substances. Students Learn To: .2 Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum. • Ethylene is produced either from natural gas or crude oil‚ which are mixtures of hydrocarbons. One method involves… Cracking: a process by which hydrocarbons with higher molecular

There is no clear description regarding food waste in a universal matter either historically or presently‚ making it perplexing in definition and comparison. What is clear is that food waste continues to grow at a rapid pace with the expansion of a world population experiencing societal and agricultural developments in an era where land and other resources are becoming more limited. The increase in waste and category of foods which people throw away has transformed with time through the advancement

Waste Disposal Waste disposal has been one of human being’s biggest problems ever since the dawn of civilization. Humans create loads of waste every day ranging from empty bottles to excretions to banana peels. What to do with all the garbage that the people create has been the discussion of panels ever since the Roman senate got together. Most of the people are not aware of the fact that putting the garbage out of their trash cans can cause many safety and environmental problems. People tend to

Batch Production Batch Production is a way of creating items in bulk. In batch production‚ general-purpose equipment and methods are commonly used to produce small quantities of items that will be made and sold for a limited time only. Usually a similar design and process will be used to make a new product‚ cars are a good example of this. Often after car has been made another version will be created that has got new features. In batch production specialized tools or items for construction purposes

the Calorific Value of Fuels Aim: To quantify the amount of energy produced by different fuels and to determine which fuel is more efficient (has a higher calorific value). Introduction: The easiest way to achieve our aim is by heating a substance with a known specific heat capacity and using the energy released from burning our fuels. This will give us the value of the heat energy released by the combustion of our two fuels. The chemical reaction for combustion: FUEL + O2

an additional 100 years? Will we raze our forests for our energy needs? I certainly hope our country will never come to those conclusions. However‚ someone must make a conclusion hopefully toward an alternate fuel source. The fuel source I would propose is biomass fuel derived from hemp. Hemp is the world’s most versatile plant. It actually improves the soil in which it grows‚ without chemical fertilizers‚ while choking out weeds by virtue of its fast dense growth. According to the U.S

will result to production of wastes and deploring public health conditions. Furthermore‚ as development progresses‚ population also grows; and apparently population growth directly affects generation of wastes‚ be it solid or liquid. As a result‚ some of the offensive wastes during the first half of this century were hazardous. Indeed‚ rapid urbanization‚ population growth and changes in lifestyles in low- and middle-income countries contribute to increasing the per capita domestic waste generation
