Torrefaction
Torrefaction of biomass, e.g., wood or grain, is a mild form of pyrolysis at temperatures typically between 200 and 320 °C. Torrefaction changes biomass properties to provide a better fuel quality for combustion and gasification applications. Torrefaction produces a relatively dry product, which reduces or eliminates its potential for organic decomposition. Torrefaction combined with densification creates an energy-dense fuel carrier of 20 to 21 GJ/ton lower heating value (LHV). Torrefaction makes the material undergo Maillard reactions. Torrefied biomass can be used as an energy carrier or as a feedstock used in the production of bio-based fuels and chemicals. Biomass can be an important energy source. However, there exists a large diversity of potential biomass sources, each with its own unique characteristics. To create efficient biomass-to-energy chains, torrefaction of biomass, combined with densification ( pelletisation or briquetting), is a promising step toward ...

Agricultural Waste
Agricultural waste are plant residues from agriculture. These waste streams originate from arable land and horticulture. Agricultural waste are all parts of crops that are not used for human or animal food. Crop residues consist mainly of stems and leaves. It is estimated that, on average, 80% of the plant of such crops consists of agricultural waste. The four most commonly grown agricultural crops worldwide are sugarcane, maize, cereals and rice. The total weight of all these crops is more than 16,500 billion kilograms per year. Since 80% of this consists of agricultural waste, many tens of thousands of billions of kilograms of agricultural waste remain worldwide. Some 700 million tonnes of agricultural waste is produced annually by the EU. Recycling agricultural waste Agricultural waste consists mainly of cellulose, hemicellulose and lignin. Agricultural waste is poorly digestible and in unprocessed form not widely suitable as animal feed. Globally, most agricultural waste i ...

Biochar
Biochar is the lightweight black residue, made of carbon and Ash (analytical chemistry), ashes, remaining after the pyrolysis of biomass. Biochar is defined by the International Biochar Initiative as "the solid material obtained from the thermochemical conversion of biomass in an reducing atmosphere, oxygen-limited environment". Biochar is a stable solid that is rich in Pyrolysis, pyrogenic carbon and can endure in soil for thousands of years. The refractory stability of biochar leads to the concept of pyrogenic carbon capture and storage (PyCCS), i.e. carbon sequestration in the form of biochar. It may be a means to Climate change mitigation, mitigate climate change. Biochar may increase the soil fertility of acidic soils and increase agricultural productivity. History The word "biochar" is a late 20th century English neologism derived from the Greek Language, Greek word , ''bios'', "life" and "Char (chemistry), char" (charcoal produced by carbonisation of biomass).

Charcoal Burning
A charcoal burner is someone whose occupation is to manufacture charcoal. Traditionally this is achieved by carbonising wood in a charcoal pile or kiln. Charcoal burning is one of the oldest human crafts. The knowledge gained from this industry still contributes to the solution of energy problems today. Due to its historical and cultural importance, charcoal burning and tar distilling were incorporated in December 2014 into the register of the Intangible Cultural Heritage in Germany by the ''Kultusministerkonferenz''. History and technique Medieval charcoal burners Since the Iron Age, high temperatures have had to be produced for iron smelting, for glassmaking, and for the working of precious metals. Charcoal has been used to do this for centuries and, in order to produce it, entire forests were felled. With the increasing use of stone coal from the 18th century, the charcoal burning industry declined. Even in ancient times, charcoal was manufactured in kilns. Logs were ...

Stubble Burning
Stubble burning is the practice of intentionally setting fire to the straw crop residue, stubble that remains after grains, such as rice and wheat, have been harvested. The technique is still widespread today. Effects The burning of stubble has both positive and negative consequences. Generally helpful effects * Cheaper and easier than other removal methods * Helps to combat pests and weeds * Can reduce nitrogen tie-up Generally harmful effects * Loss of nutrients * Pollution from smoke. Including greenhouse gases and others that damage the ozone layer * Damage to electrical and electronic equipment from floating threads of conductive waste * Risk of fires spreading out of control Alternative to stubble burning Agriculture residues can have other uses, such as in particle board and biofuel, though these uses can still cause problems like erosion and nutrient depletion, nutrient loss. Spraying an enzyme, which decomposes the stubble into useful fertiliser, improves the soil, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Pollution In Delhi
The air quality in Delhi, the capital territory of India, according to a WHO survey of 1,650 world cities, and a survey of 7,000 world cities by the US-based Health Effects Institute in August 2022, is the worst of any major city in the world. It also affects the districts around Delhi. Air pollution in India is estimated to kill about 2 million people every year; it is the fifth largest killer in India. India has the world's highest death rate from chronic respiratory diseases and asthma, according to the WHO. In Delhi, poor quality air irreversibly damages the lungs of 2.2 million or 50 percent of all children. On 25 November 2019, the Supreme Court of India made statements on the pollution in Delhi saying "Delhi has become worse than '' narak'' (hell)". Supreme Court Justice Arun Mishra said that it is better to get explosives and kill everyone. During the COVID-19 pandemic lockdown in India, The water quality of the Yamuna and Ganges river basins have improved as indus ...

Fossil Fuel
A fossil fuel is a hydrocarbon-containing material formed naturally in the Earth's crust from the remains of dead plants and animals that is extracted and burned as a fuel. The main fossil fuels are coal, oil, and natural gas. Fossil fuels may be burned to provide heat for use directly (such as for cooking or heating), to power engines (such as internal combustion engines in motor vehicles), or to generate electricity. Some fossil fuels are refined into derivatives such as kerosene, gasoline and propane before burning. The origin of fossil fuels is the anaerobic decomposition of buried dead organisms, containing organic molecules created by photosynthesis. The conversion from these materials to high-carbon fossil fuels typically require a geological process of millions of years. In 2019, 84% of primary energy consumption in the world and 64% of its electricity was from fossil fuels. The large-scale burning of fossil fuels causes serious environmental damage. Over 80% of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
