Zero Waste Agriculture
Zero waste agriculture is a type of sustainable agriculture which optimizes use of the five natural kingdoms, i.e. plants, animals, bacteria, fungi and algae, to produce biodiverse-food, energy and nutrients in a synergistic integrated cycle of profit making processes where the waste of each process becomes the feedstock for another process. History The integration of shallow oxidisation ponds of microalgae was demonstrated by Golueke & Oswald in the 1960s. The widespread global implementation of these systems can be largely credited to Prof George Lai Chan-Yu-Thim (02 March 1924 Mauritius-08 October 2016 Mauritius) from ZERI. Zero waste agriculture is now practiced in China (ecological farming), Columbia (integrated food & waste management systems) & Fiji (integrated farming systems), India (integrated biogas farming), South Africa (BEAT Coop & African Agroecological Biotechnology Initiative) and Mauritius. The Brazilian government has adopted integrated farming system as a ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biomethane
Renewable natural gas (RNG), also known as sustainable natural gas (SNG) or biomethane, is a biogas which has been upgraded to a quality similar to fossil natural gas and having a methane concentration of 90% or greater. By increasing the concentration of methane to a similar level as natural gas, it becomes possible to distribute the gas to customers via the existing gas grid and use in existing appliances. Renewable natural gas is a subset of synthetic natural gas or substitute natural gas (SNG). Multiple ways of methanising carbon dioxide/monoxide and hydrogen exist, including biomethanation, the Sabatier process and a new electrochemical process pioneered in the United States currently undergoing trials. Advantages Renewable natural gas can be produced and distributed via the existing gas grid, making it an attractive means of supplying existing premises with renewable heat and renewable gas energy, while requiring no extra capital outlay of the customer. The existing gas net ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sustainable Agriculture
Sustainable agriculture is farming in sustainable ways meeting society's present food and textile needs, without compromising the ability for current or future generations to meet their needs. It can be based on an understanding of ecosystem services. There are many methods to increase the sustainability of agriculture. When developing agriculture within sustainable food systems, it is important to develop flexible business process and farming practices. Agriculture has an enormous environmental footprint, playing a significant role in causing climate change (food systems are responsible for one third of the anthropogenic GHG emissions), water scarcity, water pollution, land degradation, deforestation and other processes; it is simultaneously causing environmental changes and being impacted by these changes. Sustainable agriculture consists of environment friendly methods of farming that allow the production of crops or livestock without damage to human or natural systems. It ...

Miniwaste
Miniwaste was a European project operated from January 2010 to December 2012, designed to "bring bio-waste back to life". In other words, it was intended to demonstrate that it is possible to significantly reduce the amount of bio-waste at a local level. The project was co-funded by the LIFE+ programme of the European Commission. The project emphasized the efficiency and sustainability of bio-waste reduction actions at source, in particular by organising demonstration actions and trainings for the population, and by offering a better way of evaluating and controlling waste prevention. Main goals The project endeavors to demonstrate, in accordance with the recent Waste Framework Directive, that it is possible to significantly reduce the amount of organic waste (also called "bio-waste", covering both food and green waste) at the source in a sustainable way, and to monitor actions for waste reduction in an efficient manner. The Miniwaste project has four main objectives: * to gathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agritech
Agricultural technology or agrotechnology (abbreviated agtech, agritech, AgriTech, or agrotech) is the use of technology in agriculture, horticulture, and aquaculture with the aim of improving yield, efficiency, and profitability. Agricultural technology can be products, services or applications derived from agriculture that improve various input/output processes. Advances in agricultural science, agronomy, and agricultural engineering have led to applied developments in agricultural technology. History The history of agriculture has been shaped by technological advances. Historians have described a number of agricultural revolutions, which identify major shifts in agricultural practice and productivity. These revolutions have been closely connected to technological improvements. Irrigation technology was developed independently by a number of different cultures, with the earliest known examples dated to the 6th millennium BCE in Khuzistan in the south-west of present-day Iran. ...

Biodiesel
Biodiesel is a form of diesel fuel derived from plants or animals and consisting of long-chain fatty acid esters. It is typically made by chemically reacting lipids such as animal fat (tallow), soybean oil, or some other vegetable oil with an alcohol, producing a methyl, ethyl or propyl ester by the process of transesterification. Unlike the vegetable and waste oils used to fuel converted diesel engines, biodiesel is a drop-in biofuel, meaning it is compatible with existing diesel engines and distribution infrastructure. However, it is usually blended with petrodiesel (typically to less than 10%) since most engines cannot run on pure Biodiesel without modification. Biodiesel blends can also be used as heating oil. The US National Biodiesel Board defines "biodiesel" as a mono-alkyl ester. Blends Blends of biodiesel and conventional hydrocarbon-based diesel are most commonly distributed for use in the retail diesel fuel marketplace. Much of the world uses a system know ...

Energy Security
Energy security is the association between national security and the availability of natural resources for energy consumption. Access to (relatively) cheap energy has become essential to the functioning of modern economies. However, the uneven distribution of energy supplies among countries has led to significant vulnerabilities. International energy relations have contributed to the globalization of the world leading to energy security and energy vulnerability at the same time. Renewable resources exist worldwide across every biome except the North and South Poles (only nuclear (and wind in the winter) is feasible), in contrast to fossil fuels, which are concentrated in a limited number of countries. Nations don't switch from unpredictable fossil fuels to renewables overnight. It is a long, continuous process. Rapid deployment of renewable energy, increased energy efficiency, and diversification of energy sources, energy stores, and types of energy machines can use all ...
