Aristotle says, for example, that the ratio 2:1, and number in general, is the formal cause of the octave. Efficient, or agent The efficient or moving cause of a change or movement.
The final action is disposal, in landfills or through incineration without energy recovery. This last step is the final resort for waste that has not been prevented, diverted, or recovered. [18] [page needed] The waste hierarchy represents the progression of a product or material through the sequential stages of the pyramid of waste management ...
Economic returns – more efficient use of products means reduced costs of purchasing new materials, improving the financial performance of a company. Public image – the environmental profile of a company is an important part of its overall reputation and waste minimisation reflects a proactive movement towards environmental protection .
Material efficiency is a description or metric ((Mp) (the ratio of material used to the supplied material)) which refers to decreasing the amount of a particular material needed to produce a specific product. [1] Making a usable item out of thinner stock than a prior version increases the material efficiency of the manufacturing process.
The adoption of a unique bin for a wide range of recyclables may cause contamination problems, [127] but it has the side-effect of diminishing the number of trucks (and consequently air pollution), required for the collection processes. [50] The contamination of the materials collected causes the diversion of recyclables to landfills.
Again, this reduces the distance that vehicles have to travel between the initial and final destinations. Railroads that reach all the way to ports are a significant way to produce less toxic pollutants, as this eliminates the need for less-efficient trucks to transport the goods from the coastal port to the inland railroad infrastructure.

Aristotle categorized the four types of answers as material, formal, efficient, and final "causes". In this case, the "cause" is the explanans for the explanandum, and failure to recognize that different kinds of "cause" are being considered can lead to futile debate. Of Aristotle's four explanatory modes, the one nearest to the concerns of the ...
Pollution is the introduction of contaminants into the natural environment that cause harm. [1] Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
