  2. Waste management - Wikipedia

    en.wikipedia.org/wiki/Waste_management

    Different types of waste input (such as plant waste, food waste, tyres) placed in the pyrolysis process potentially yield an alternative to fossil fuels. [53] Pyrolysis is a process of thermo-chemical decomposition of organic materials by heat in the absence of stoichiometric quantities of oxygen ; the decomposition produces various hydrocarbon ...

  3. Bulk modulus - Wikipedia

    en.wikipedia.org/wiki/Bulk_modulus

    where is the initial density and / denotes the derivative of pressure with respect to density. The inverse of the bulk modulus gives a substance's compressibility . Generally the bulk modulus is defined at constant temperature as the isothermal bulk modulus, but can also be defined at constant entropy as the adiabatic bulk modulus.

  4. Thermodynamic diagrams - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_diagrams

    The main feature of thermodynamic diagrams is the equivalence between the area in the diagram and energy. When air changes pressure and temperature during a process and prescribes a closed curve within the diagram the area enclosed by this curve is proportional to the energy which has been gained or released by the air.

  5. Packaging waste - Wikipedia

    en.wikipedia.org/wiki/Packaging_waste

    This is a major issue for low income countries who do not have an efficient waste management system to clean up their environments and being the main sources for the global ocean pollution. [4] But 'litter louts', individuals who lack the motivation to recycle and instead leave their waste anywhere they want are also major contributors ...

  6. Van der Waals equation - Wikipedia

    en.wikipedia.org/wiki/Van_der_Waals_equation

    Thus he argued that in his case the attractive pressure was proportional to the square of the density. [13] The proportionality constant, ⁠ a {\displaystyle a} ⁠ , when written in the form used above, has the dimension [pv 2 ] (pressure times molar volume squared), which is also molar energy times molar volume.

  7. Relative density - Wikipedia

    en.wikipedia.org/wiki/Relative_density

    A United States Navy Aviation boatswain's mate tests the specific gravity of JP-5 fuel. Relative density, also called specific gravity, [1] [2] is a dimensionless quantity defined as the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material.

  8. Reference atmospheric model - Wikipedia

    en.wikipedia.org/wiki/Reference_atmospheric_model

    (See graph.) Of course the real atmosphere does not have a temperature distribution with this exact shape. The temperature function is an approximation. Values for pressure and density are then calculated based on this temperature function, and the constant temperature gradients help to make some of the maths easier.

  9. Food loss and waste - Wikipedia

    en.wikipedia.org/wiki/Food_loss_and_waste

    Food and agriculture nonprofits (FANOs) are an understudied player in food system sustainability and food waste management ([81]). FANOs play an essential role at every step of the food supply chain ([81]) including in creating or preventing food waste ). Food waste can be defined as edible food discarded by consumers.
