and has an average of 26oC. Sandikhola has a two-season year made up of the dry and wet seasons. The dry season runs from October to May and the wet season from June to September. 2.1 Fuel for cooking Villagers use firewood, which they get, from community forests where each community has its own allocation of wood. Buffalo and cow dung mixed with water and then fed into a reactor is used to provide villagers with biogas. 2.2 Effects of the cooking techniques used Firewood storage takes up a lot of
people rely on biomass, such as fuel wood, charcoal, agricultural waste and animal dung; to meet their energy needs for cooking. In many countries, these resources account for over 90% of household energy consumption. In the absence of new policies, the number of people relying on biomass will increase to over 2.6 billion by 2015 and to 2.7 billion by 2030 because of population growth. That is, one-third of the world’s population will still be relying on these fuels. There is evidence that, in areas
happen everyday. Two main natural chemical changes are; combustion e.g; wood burning, and the metabolism in the human body. Two man made chemical changes are; gas bombs which are used in the military, and the rusting or iron (nails). Combustion is a chemical combination or change resulting in the production of heat and light. Essentially, wood burning is one of the main forms of combustion. When wood is burnt, the carbon in the wood reacts against the oxygen in the air which then creates ash and smoke
key points. A fire needs three elements: air, fuel, and an ignition of some kind. For a campfire the air element is easily accessible; it's the air a person breaths or oxygen. Fuel is equivalent to wood. Sometimes lighter fluid is used to start big fires immediately, but usually when dealing with a campfire the fuel is wood. Ignition can come from a spark, match, or lighter. It is anything that initially starts the fire. Going deeper into wood, there are three categories to classify it under
Investigate whether firelighter, wood, ethanol, paraffin or wax contains the most energy Energy In Different Fuels Aim: I am going to investigate which fuels contain the most energy between; firelighter, wood, ethanol, paraffin and wax. Prediction: I think that the fuel that contains the most energy is the one that produces the highest rise in temperature of the water. I know this because… Heat + fuel + oxygen => CO2 + H20 + energy. The energy realised is heat and light energy, which is dependent
As the basic material for buildings, transportation, and fuel, wood was a necessity for the growth and development of the ancient civilizations. Wood was the key resource used in the construction of houses and ships and it was the primary fuel source for light and heat in households and public facilities. As a result of the many needs the resource satisfied, the word wood in the Greek and Latin languages was synonymous with substance or matter (Hughes P. 74). The constant use and growing demand
would have to use wood. People have been using wood for years, but do you know which kind of wood to use so that your fire burns for the longest amount of time possible or for the shortest amount of time? Fire is chemical reaction between oxygen and a type of fuel. To make a fire you must heat the fuel to its ignition temperature. Things that can light wood are matches, focused light, friction, etc… These things heat the wood to its ignition temperature, but different types of wood can have an unsimilar
an epidemic of forest depletion that gradually spread to the lands they encountered. Beginning in the early fourteenth century, wood fueled the increased production of exploratory sea vessels. The loss of trees coincided with the rapid rate of shipbuilding. Eventually, Europeans exploited their timber reserves to such an extreme that they began looking elsewhere for wood, including colonies in North America and Southeast Asia. With newfound resources, the European shipbuilding machine churned on,
Wood chippers are available in a variety of sizes, so pick one that best fits the size of the wood you need to turn into mulch. Remember also to have the wood chipper rental shop give you thorough instructions on how to safely and effectively operate the wood chipper you lease. Log Splitter Mulch isn't the only thing you can make from the wood left over from tree-trimming. You can likewise transform that heaping log pile into a vast supply of heating fuel to use in your home's
passed down from grandfather to father to son. Wood from downed trees is our primary source of heat via fireplaces and wood furnaces. Few people comprehend the real dangers involved with cutting down a tree. Every year, thousands of people are hurt in tree falling related accidents. These six steps will provide instruction on how to safely cut down a tree. First, the chainsaw should be filled with the proper fuel to operate. Most saws need mixed fuel, which is gas mixed with oil. This is necessary
or electric wood splitter but these can be very expensive. So we are going to focus on the most economical tool for the job, the mall. While at first glance a mall can be mistaken for an axe but it is much heavier than the latter. A mall is also a little duller then the axe because it is meant for severing and not slicing. You need to keep your mall reasonably sharp so it does not bounce of the wood.
Pennsylvania with papermaking plants and wood yard located throughout the United States. Glatfelter also has international operations in Germany, France, United Kingdom, Canada and the Philippines. The Chillicothe plant is a pulp and papermaking plant. Essentially it is two plants in one since pulp and papermaking are sometimes separated. The papermaking process begins with pulp. Pulp is cellulosic fibrous material extracted from cellulosic fiber from wood. Glatfelter uses the Kraft Process to make
In terms of sustainability, initial decisions in the design process can significantly help deliver results. Evaluations and explorations through the impact of materials, such as concrete, wood, bricks, masonry, and steel, can help improve reductions in energy through its applicability to a building. While wood and steel are simply identified for their strength, durability, and functionality in structures, accentuating these materials’ embodied energies and recyclability offer a more comprehensive
resources and opportunity. Settlers began using trees and wood in a plethora of ways. Not only was it used for families own use, many began logging forests as a business; a very profitable business at that. Once wood started being used for beneficial purposes, a snowball effect occurred by the settlers to cut down every tree in sight and turn it into a profit. Logging was the process of cutting down numerous amounts of trees to use wood in a capitalist way or to clear land for agricultural purposes
organization of this company does not have a steady foundation due to the political structure of Honduras. Guajilote also the amount of mahogany wood was limited and was being threatened by forest fires, illegal logging, and slash and dash burn agriculture. Wood trade was even restricted internationally. Guajilote was force to take lower price for its wood due to that there was only one distributing area. Most if not all of Guajilote employees had any education beyond primary schooling, and some were

Rainforests are the most productive and most complex ecosystems on Earth. Amazon rainforest alone produces 20% of the world’s oxygen. Therefore, the consequences of destroying it will be very harsh on us humans. If we take the resources such as wood from the rainforest, for our everyday use now, we will be the ones suffering in long term. Rainforest use to cover 14% of our earth, and now its left with only 6%. From looking at the rainforest from different perspective actually tells us a

quickly feel a very cold chill. You than get up to look if there is any windows open but you remember that there is no heat, you than have to go outside in the -40 weather and get logs for a wood fire. Without our furnaces or air conditioning systems we would need to have wood stoves in our homes and refill them with wood every couple hours, which would take some time and energy than just touching a button to adjust the temperature. Next you go to the washroom and quickly jump in the shower because you
