has made the solid wastes a significant portion of waste generated from households. Solid waste generation across the world Rapid economic development has increased the living standard of the people across the globe. This has directly translated into more material consumption and more waste generation. Driven by consumption of resources‚ high income countryies produce roughly 1.1 to 5.0 kg solid waste per capita for a day; middle-income countries generate between 0.52 and 1.0 kg solid waste per capita

CHAPTER I BACKGROUND OF THE STUDY Solid waste disposal is both an urban and rural problem. Person is a potential generation of waste and thus a contribution to this problem. to generate is one thing‚ the type of waste generated is another and now also the way of generated waste is to manage or dispose of it’s quite different issue. Solid waste is any material which comes from domestic and industrial sources from human activities which has no value to people who possess it and

The very first experiment had the hypothesis that the temperature of a burner flame can be controlled by adjusting the ratio of gas to air in the mixture to be burned. During this experiment‚ my partner and I gathered our materials of the paper matches‚ straight pins‚ copper wire‚ laboratory burners‚ rubber tubing‚ tongs‚ and evaporating dish. Making sure we had our safety goggles on and the material we needed‚ we connected the Tirrill burner into the gas and lit the burner with the match‚ having

A safety audit for the gas-solid fluidization experiment was conducted. The following safety concerns were found when performing the audit: operating beyond the operating limits‚ spillage of the beads‚ risk of head injury from bending over to change the beads in the apparatus or from the low bar‚ and congestion of the workspace. One of the biggest safety concerns with this lab involved the small glass beads that acted as the solid in the experiment. If the gas flow rate goes below 50 standard cubic

AIMS At the end of the experiment‚ students should be able to synthesise pure aspirin using chemical tests such as esterification and recrystallization independently and to also find out the melting point range of aspirin using melting point determination. INTRODUCTION Aspirin‚ which is also known as acetylsalicylic acid‚ is one of the commonly used and widely found in any drugstore or pharmacy. Its properties make aspirin a well-rounded drug that reduces inflammation and fever and also relieves

Photography Write-Up: Separation The camera I use has been rented from the ERC on a regular basis‚ and is a Canon 600D or 700D. The photo’s i’ve captured for this project were shot on the standard lens‚ with a variety of settings. I also often use a mini LED light with a daylight filter in order to create more depth in the shadows in my images‚ I usually place this somewhere away from the camera in order to create angled shadows instead of images being frontlit. To start this project‚ I experimented

and Purification of Solids Melting Point Lab Introduction: The point of this lab was to determine the eutectic point for the naphthalene biphenyl mixture‚ as well as determining the melting point of an unknown substance by comparing it with two known samples. Melting point is a temperature in which a substance changes from solid state to liquid state. Melting points are used to determine whether the given substance is pure or not. Substances that melt sharply‚ less than 1-2°C indicates pure substance

purpose of this lab was to identify the reaction type‚ balance equations‚ and observe the reactions .Our hypothesis was if there was many stations with fire‚ then they’re would be many combustion reactions. The procedure of the first lab was to place a solid piece of magnesium metal in the bottom of the smallest tube. Place this test tube in the test tube holder. Using tongs pick up the large test tube and have it turned upside down‚ ready for the reaction. Place 6 drops of HCL into the small test tube

Parachute experiment Aim: The aim was to find the effect of holes on a parachute‚ varying their size and number. Hypothesis: 1. By increasing the number of holes‚ the time it will take to the parachute to reach the ground will be longer and its flight will be more balanced. 2. By increasing the size of the hole on the parachute‚ the time it will take to the parachute to reach the ground will be shorter and its flight will be less balanced. Apparatus: - garbage bag (squared shape

United States believe that America has been struck with a "trash crisis"‚ however‚ this is not truly case from the recent Environmental Protection Agency (EPA) facts for 2010. Before‚ we start let us take a moment to discuss what trash or municipal solid waste (MSW) is. MSW is the collection of commonly used items that discarded by the general populace‚ many of these include packaging‚ food scraps‚ grass clippings‚ sofas‚ computers‚ tires and house appliances (EPA). Although the information from the
