Zero Waste Agriculture is a farming technique that has been developed for well over 3000 years now and is still used with success in today's farming industry.
The Zero Waste Agriculture technique is a system which incorporates a number of farming processes such as the rearing of animals (cows, pigs, chickens, etc), the growing of fungi and plants, fish farming and the production of natural gases and oils, etc.
In theory this particular type of farming produces materials and stock that can be sold to make a profit and in the process of doing so produces no wastage whatsoever. The reason there is no wastage is because all of it is recycled to become a bio-diverse food energy or nutrients that will then be used to feed the stock and other processes such as fertilizers.
Zero Waste Agriculture is a system which is found to be used all over the world it produces materials and stock with little or no waste and is a technique that is totally self sufficient.
The Benefits of Zero Waste Agriculture
There are many benefits to this particular type of farming. Not only is it an ecological farming practice, but it also generates a lot of job opportunities. In areas of poverty it can be used as a reliable source of food, energy and help conserve water supplies.
The Zero Waste Agriculture technique is found to be used and practiced on small family sized farms in third world countries, 
and it complements traditional farming and animal husbandry as practiced in most third world communities. Zero Waste Agriculture also preserves local indigenous systems and existing agrarian cultural values and practices.
Zero Waste Agriculture presents a balance of economically, socially and ecologically benefits as it:
- optimizes food production in an ecological and sound manner
- reduces water consumption through a process of recycling and reduced evaporation
- provides energy security through the harvesting of bio-methane (biogas) and the extraction of bio-diesel from micro-algae all of which form as a by-product of food production
- provides climate change relief through the substantial reduction in greenhouse gas emissions from both traditional agriculture practices and fossil fuel usage
- reduces the use of pesticides through bio-diverse farming
Getting Oil and Bio-diesel from Algae
In sunny climates, a one hectare zero waste farm can produce over 1000 litres of oil in a year from the chlorella micro algae grown on biogas digester effluent in a 500m2 shallow pond. The nutritive high protein waste from the oil extraction process can be used as an animal feed.
