II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
The potential difference above the equilibrium value required to produce a current which depends on the activation energy of the redox event.

This idea can be applied to logistics as well. In the past, logistic cost has been defined in purely monetary terms. However, as not only in the EU but also in the USA and other countries became more and more aware of environmental problems ,for instance because of climate change, air pollution, noise and accidents, environmental considerations has been taken in logistics kfield. This is how Gree
