Waste to Energy Introduction Waste to energy (WTE) is a process that converts waste materials into energy. This can be done through a variety of methods, including incineration, gasification, and pyrolysis. WTE can be a valuable tool for managing waste and reducing greenhouse gas emissions. How does waste to energy work? There are a number … Read more
What is Cogeneration? Cogeneration is the simultaneous production of two useful forms of energy, such as electricity and heat, from a single fuel source. This is in contrast to conventional power plants, which only produce electricity. Cogeneration can be used in a variety of applications, including hospitals, hotels, schools, and manufacturing facilities. How does Cogeneration … Read more
Combustion/Incineration Combustion is a chemical reaction that occurs between a fuel and an oxidizer, releasing heat and light. The most common type of combustion is the burning of fossil fuels, such as coal, oil, and natural gas. Combustion is also used in many industrial processes, such as the production of electricity and the manufacture of … Read more
Pyrolysis/Gasification Pyrolysis and gasification are two thermochemical conversion processes that are used to convert organic materials into a variety of products, including fuels, chemicals, and biochar. Pyrolysis is a thermal decomposition process that occurs in the absence of oxygen, while gasification is a partial oxidation process that occurs in the presence of a limited amount … Read more
Anaerobic digestion is a process that converts organic waste into biogas and digestate. Biogas is a renewable energy source that can be used to generate electricity, heat, or fuel vehicles. Digestate is a nutrient-rich soil amendment that can be used to improve crop yields. Anaerobic digestion is a natural process that occurs in the absence … Read more
Phytoremediation: A Green Approach to Environmental Remediation Phytoremediation is a cost-effective and environmentally friendly approach to environmental remediation that uses plants to remove, transform, or stabilize contaminants in soil, water, and air. How does phytoremediation work? Plants take up contaminants through their roots and either transform them into less harmful compounds or store them in … Read more
Mycoremediation is a process that uses fungi to clean up environmental contamination. Fungi are naturally occurring organisms that have the ability to break down and absorb pollutants, making them ideal for use in environmental remediation. Mycoremediation can be used to treat a variety of contaminants, including heavy metals, pesticides, and petroleum hydrocarbons. Fungi can also … Read more
Biopiles are a type of bioreactor that uses organic materials to treat contaminated soil. They are typically constructed in a lined trench or lagoon, and the organic materials are added to the pile along with water. The organic materials provide a food source for microorganisms, which break down the contaminants in the soil. Biopiles can … Read more
