Study Notes
Torrefaction Process
- Primary output is biochar, a charcoal-like substance used for energy storage and soil enhancement.
Circular Economy Principles
- Extending the lifespan of products is linked to the principle of "reducing waste through reuse and repair."
Waste-to-Energy Technologies
- Incineration involves burning biomass in the presence of oxygen to generate energy.
Linear Economy Model
- The primary objective is to maximize production and consumption, often leading to excessive waste generation.
Feedstock for Anaerobic Digestion
- Organic waste, including food scraps and agricultural residues, is commonly used as feedstock.
Conversion to Liquid Biocrude
- Pyrolysis is the process that converts organic materials into liquid biocrude through thermal decomposition without oxygen.
Mechanical Biological Treatment (MBT)
- Key objective in waste management is to reduce the volume of waste sent to landfills by extracting recyclable materials and stabilizing organic waste.
Gasification Process
- Materials with high moisture content, such as food waste, are least suitable for conversion through gasification.
Misconceptions about Circular Economy
- A common misconception is that the circular economy is solely about recycling, neglecting other important aspects like repair, reuse, and redesign.
High-Temperature Waste Treatment
- Plasma gasification involves high-temperature treatment of waste in the absence of oxygen to produce syngas and other by-products.
Environmental Benefit of Landfill Gas Conversion
- A significant benefit is the reduction of greenhouse gas emissions, as converting landfill gas to energy prevents methane from contributing to climate change.
