Turning Food Waste into Energy
Humans currently waste around a third of all the food produced on Earth. Why is that such a problem? When food rots in landfills, it emits methane, a potent greenhouse gas that contributes to climate change.
The resources needed to grow our food and power our economies are having a tremendous impact on natural energy resources. Increasing populations and growing energy demands are depleting these resources at ever-increasing rates.
The growing scale of food waste for many countries has significant implications on public health, environmental pollution, and shortages of safe and secure dumping land far from human settlements. A global response to combating these and other growing problems has seen numerous countries pledge to reduce greenhouse gas emissions.
Through the conscious and responsible use of food waste, households, businesses, and governments can make use of what can no longer be used and turn it into a renewable energy source.
Anaerobic digestion is a process whereby microorganisms break down biodegradable material (such as food waste) in the absence of oxygen. The energy captured through this process in the form of Biogas can be burned to produce electricity and heat.
The benefits of using Biogas as a renewable energy source to help us in reducing our dependence on fossil fuels cannot be understated. As a non-polluting energy source, turning food waste into energy means improved air quality as fewer toxic gases are released into the air and smaller landfill sites.
For businesses, adopting standard management practices for food waste and recycling means reduced costs. Companies can produce their own energy and avoid paying fees for excess waste removal.
The value of food waste as a natural resource will also continue to increase as new and improved methods can be applied to manufacture fuels, chemicals, and materials such as plastics and feed clean energy back into national electrical grids.
ALLGAIER's process technology is perfectly suited to the preparation and processing of highly diverse food waste types.
GOSAG densimetric tables efficiently separate products with different specific densities. Its robust design makes it suited for operating in harsh conditions where wear protection is needed to ensure a long lifespan.
Both dry and moist food waste can be separated using GOSAG densimetric tables, especially effective when used to separate low-density products and medium particle sizes.
For foodstuffs with a high density and grain size, up to 80mm, the GSort beats established sorting methods with an increase in performance of up to 80%.
The GSort reduces processing costs while also being environmentally friendly. Dry separation of products improves water management and significantly helps in reducing energy consumption per metric ton. Its easy handling, operation, and versatility are an example of an intelligent combination of the latest technology and traditional engineering
ALLGAIER has recently launched the CDry Foodan indirectly heated contact dryer specially designed for the food industry.
Developed to be space-saving and efficient, this innovative dryer meets the food industry's strict hygiene guidelines and standards for dealing with foodstuffs and waste by-products.
The CDry Food also allows for significant control of the taste of end products not destined for energy production. Able to accommodate a wide field of applications, the CDry's numerous advantages make it a leading technology for any process application in the foodstuffs industry.
