Briquetting
Briquetting is a mechanical compaction process of binding together pulverized materials into briquette under high pressure, often with the help of a binder. These high density solid blocks can be used as a fuel to replace fossil fuels or wood for cooking and industrial processes. Furthermore, they are cleaner and easier to handle, and cut greenhouse gas emissions.1 This process is used for forming fine particles into a geometric shape and practically identical weight and it increases the density of bulky materials. It is considered as an energy and waste control measure in the production of briquetted from any biomass wastes. However, depending on the wastes of interest, briquetting can be used as fuel source

This art is subdivided into two parts:-
• Compacting of loose material other combustible waste products to improve the volumetric calorific value of fuel
• Agglomeration of the materials so that the briquette stay in the compressed state for use in energy production.
Compaction mechanism4
Mani et al. (2002) postulated that there are three stages during densification of biomass.
1st stage : . In the first stage, particles rearrange themselves to form a closely packed mass where most of the particles retain their properties and the energy is dissipated due to inter-particle and particle-to-wall

trapped it beneath the rock. Press/heat changed some of it to coal, oil, and natural gas;
The main reason people have not converted to cleaner, healthier fuel is that hybrid and electric cars are more expensive than the cars and gasoline we are using now. However, we could implement a program for selling cleaner fuel at a lower cost than it is now offered. If this program were organized correctly, the increased costs would be minimal in the long run and the benefits would be enormous. After considering several possibilities, I concluded that alcohol-burning cars are more practical than other environmentally friendly options because electric and hybrid cars or cars that run on natural gas are more expensive and are less convenient to refuel.
I have thought it useful, in the interest of science,’ he wrote, ‘to make known the effects of charcoal upon man. I place a lamp, a candle, and a watch on my table, and commence the ceremony. It is a quarter past 10; I have just lighted the stove; the charcoal burns feebly’. (Lewes, 1859, pp.347‑8)
For example, Hydrofracking; What is hydrofracking? Gas industries use hydrofracking to extract natural gases from shale ground in order to power Americans homes. When gas industries hydrofrack, they dig ten-thousand feet into the mantle of the earth and turn perpendicular to the t into shale layers with cement and steel casing to prevent leaks. Then rupture the layer of sediment with high pressures of water, sand and a plethora of chemicals. Once the chemicals are saturated in the crevices of the drill site, they extract the excess fluid and then ship them to market.
Cars are a fantastic invention. They make our lives even more carefree by getting us from place to place quickly while eradicating the need for legs altogether. There is no doubt that the benefits of driving from place to place are numerous. However, driving takes a whole lot of fuel, and everyone knows that fuel for cars isn’t the most plentiful (or cheapest!) of resources.
...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.
Waste incineration units produce a lot of carbon dioxide gas approximately around one third of the greenhouse gasses. It also impacts people’s health as they get exposed to the toxic emissions by breathing in the air or consuming contaminated food and water. Additionally, when the garbage gets burnt by the incinerators they end up as ashes which are then emitted from the chimneys, including the toxic materials and end up in specialist landfill sites for hazardous waste.
It decreases the chances for caking of partially hygroscopic materials, in case of storage as a powder. This is achieved since the moisture is adsorbed onto the surface of the granulated particles and they can still maintain their flowability due to its size(1).
Burning waste is not good at all for human health. It’s disturbing smell cause by burning plastic, rubber and some other artificial object can cause lot of trouble...
Arson is one of the oldest crimes recognized throughout the world. It is defined as the intentional and malicious burning of a structure or building (Montaldo). Arson can cost the lives of individuals and the damages can be costly. In 2010, there were about 260,600 fires (“Arson and Intentional Fires,” n.d.). Many of these fires were intentionally set. These fires have resulted in an estimated 390 deaths, 1,340 injuries, and $1.2 billion in damages (“Arson and Intentional Fires,” n.d.). Most of the fires have occurred outside, but most of the deaths, injuries, and losses occurred in structures, particularly in homes (“Arson and Intentional Fires,” n.d.). Arson is considered to be a property crime to law enforcement agencies, despite that the fires created by the arsonist can injure and kill many people. This paper will discuss the history of arson as well as explaining why arson is difficult to prove, why people commit it, and also provides specific case examples and suggestions on what people can do to reduce the risk of arson.
...on processes. The process of initiation of the process leading to conditions that allow the occurrence, Crystals core formation, the initiation process can be carried out by cooling, evaporation, and combinations. Crystal nucleation is the process of formation, the occurrence of crystallization conditions is a natural occurred in the area above the curve is saturated, and is added from outside of the seed crystal. The process of crystal formation occurs in solute than normal conditions. That is how the process of making coffee works.
