Can we turn food waste into biogas?
Biogas is produced by breaking down the bacteria in organic waste (such as plant and animal products), in a process known as anaerobic digestion. It is a digestive process that takes place in a specially designed vessel, in an oxygen-free environment.
When turning food waste into biogas or producing biogas from food waste, anaerobic digestion is used to recycle the organic materials.
But that's not all!
The biogas produced by the food waste process separates the energy, produced by the biogas from any other solid run-off, 'digestate,' which may also be used for sustainable living.
Release of biogas from various sources
The anaerobic digestion process can occur naturally in some landfills, natural habitats, and even animal manure processing plants. It's an efficient, regulated procedure that has the potential to significantly reduce your personal contribution to landfills, while also reducing food waste, and potentially saving you money on your energy costs!
Release of biogas from food waste process
The actual production of biogas from food waste takes place in specially designed reactor (vessels).When food waste and organic waste scraps are fed to the reactor, the bacteria inside the reactor breaks down the waste, in different stages, resulting in a cascade of chemical reactions that result in biogas generation, as well as digestate runoff in liquid and solid form.
When multiple forms of organic waste are placed in the reactor simultaneously, biogas from food waste can be created faster. This is known as 'co-digestion.'
Once harvested, biogas may be utilized for a variety of sustainable living activities, including:
• Fuelling engines, turbines, and other technologies for sustainable living.
• It is being converted to bio-methane for use in a natural gas pipeline.
Who makes use of food waste biogas?
Biogas from food waste has so many applications, which include
• Renewable natural gas, including bio-methane, is processed to satisfy natural gas industry requirements. In reality, 40% of natural gas is utilized to power the national system in India. Natural gas is also utilized for heating and cooking.
• Production of liquefied natural gas and compressed natural gas.
• Digestate is produced, which is a liquid and solid by-product of anaerobic digestion.
Who utilizes biogas from food waste?
Anyone interested in sourcing and living a green energy lifestyle, can use biogas.
• Local and federal governments want to replace their reliance on expensive, inefficient, energy sources.
• Individual families want a more renewable energy-focused and sustainable way of life, such as clean energy advocates and homesteaders.
• Industries that rely on non-renewable energy sources.
Benefits of turning food waste into biogas
Using biogas from food waste will have an influence on
· Personal environmental impact, as it will reduce your dependency on non-renewable energy sources. Not only will you be producing green energy, but you will also be contributing less to landfills.
. Your utility bills. Using biogas to cook or even power your house saves money on your energy bill. In fact, one cook would provide you with enough natural energy to last up to 2 hours.
. By converting methane to biogas, you significantly reduce your carbon footprint, and personal responsibility for atmospheric emissions.
. Agricultural plans: Biogas digestate from food waste may be utilized as fertilizer, to continue producing your own organic crops. You could even sell the natural fertilizer, you make at a local farmers’ market, opening up a whole new money stream you may not have considered before.
A home biogas plant must create enough gas to suit your demands, which necessitates a steady supply of food waste. Depending on the kind of biogas plant, multiple technologies such as digestion, pyrolysis, and hydrogasification, can be used to create biogas. Finally, you should consult an expert, like Netsol Water, to choose the optimal biogas production process.
