In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface.
Prevention of food waste infers all actions that reduce food production and ultimately prevent food from being produced in vain, such as food donations or re-processing into new food products. Valorisation on the other hand comprise actions that recover the materials, nutrients or energy in food waste, for instance by producing animal feed ...

The material flow management process utilizes the Sankey diagram, and echoes the circular economy model, while being represented in media environments as a business model which may help lower the costs of production and waste. An important tool for MFM is the Sankey diagram.
Eliminating land disposal—land disposal means placing waste on or in land (e.g. injection wells, landfills, etc.), and the Land Disposal Restrictions (LDR) program (under HSWA) forbids untreated hazardous waste from land disposals, and requires the U.S. Environmental Protection Agency (EPA) to set specific treatment standards that must be met ...
