Anaerobic Digestion is one of the more promising biological technologies for sustainable waste management and has the potential to turn a large and worsening agro-headache into a growing opportunity for sustainable farming. It can extract useful biogas energy and high quality fertilizer from manure and other problematic agro waste products while also reducing the air and water pollution and emissions of greenhouse gases from a farming operation. Anaerobic Digestion harnesses natural living biological processes to maintain the natural carbon cycle and extract useful energy and fertilizer byproducts from what had been problematic waste streams. It is well suited for many types of farming operations and is an important sustainable farming practice.
UPDATE: Department of Agriculture announced a public/private partnership to help spread the use of anaerobic digester technology in dairy operations with the goal of reducing their greenhouse gas emissions by 25% by 2020.
Energy Returned on Energy Invested (ERoEI) – also sometimes referred to as EROI — is a key energy accounting metric that measures the net usable energy that can be obtained from some potential energy source after all of the various energy costs necessary to produce usable energy from the potential energy source have been subtracted from the estimated life time energy production of the potential source.
It is rapidly becoming a rather widely quoted statistic, but remains poorly understood by many people who are starting to use it or are becoming exposed to it for the first time. ERoEI is deceptively simple and seems very straightforward, but it masks a complex underlying computation that is subject to some important and arbitrary decisions. These underlying assumptions and boundary decisions have profound effects on the resulting ERoEI figure. For this reason, if for no other, it is important that as wide an audience as possible become more educated about what ERoEI means and how the many assumptions that go into a particular ERoEI calculation can lead to significantly different ERoEI figures for the same energy system.
The Lopez Community Land Trust, a non-profit, community-based organization that acquires land to hold in trust in order to provide for permanent affordable housing in an environmentally sensitive and socially responsible manner. It is offering summer and fall internships in sustainable agriculture that will offer work experience on organic farms and research work for future projects. Opportunities are available for touring permaculture operations and biodynamic farms in the area as well.
