Economad: Turning farm waste into biogas and fertiliser

Livestock are often seen as drivers of climate change - but Economad's new anaerobic digestion system, specifically designed for small to medium sized farms, can turn animal waste into valuable biogas and fertiliser. This cuts climate damaging methane emissions and helps farm businesses become more sustainable. Economad is one of the first projects to supported by the SHAKE Climate Change programme www.shakeclimate.org

Livestock itself is Not doing any harm. It's factories that do aome pollution, Still no harm. Big difference

I searched through your website and Instagram page for more information on this. Will be very interesting to see lab reports nutritional values of the bio fertiliser being produced from this.

lol you do realize this is how farmers up in North America grow your crops, right? We use cow manure dug out of barns in the spring to spread onto fields using trailers. Same thing here. They're just mixing it with water to get biomethane, and whatever solid/sludge is left gets recycled into fertilizer.

@@youseff500 bar there's no organic matter left in biogas residue, so in theory all you're doing is turning farmland into one giant hydroponic site.

[@marcosmizrahi8497]

Do you have any paper where I could find all the information?

[@atleandersen1924]

Its a bit deceptive to portray this as some sort of technological novelty or grand new idea. Large scale biogas facilities in conjunction with agriculture have been operating for more than 30 years now. Denmark, even though a small country, produced 18 PJ (petajules) of partially manure based bio-methane in 2020. From the perspective of technological challenges, its not the production of biogas, that is the issue - that basically happens automatically. The main challenges consist of stripping the roughly 50% co2 that the raw gas contains, as well as managing sulfur that often occurs in the thousands ppm range. These are unbelievably energy hungry processes, that would offset any climate gains in a heartbeat, if all you do is digest manure. Its worth mentioning that manure and slurry only has a gas potential of 15m3/tonn. This makes it un-viable without adding other types of fat/protein/carbohydrate based biomass, such as meat waste, grains, glycerine, molasses or similar. Wheat that is unfit for consumption, coarsely ground, has a methane potential of around 400m3/ton and glycerine in some cases 600m3/ton plus.

[@paddydoyle4234]

So in theory it'd pay to do away with the cows and just put the crop straight in.

[@atleandersen1924]

From a biogas perspektiv, yes, absolutely. Grains, sugar beet, corn silage, even grass silage has a far higher methane potential. However, the amount of dedicated energy crops you can use, is highly regulated and quite limited. From 2024 its just 4% of total biomass

[@estebancorral5151]

What use would put the CO2 to? Otherwise at 50% byproduct it is a pollutant.

[@ericomfg]

Why would that co2 be bad...? Wouldn't that be good?

[@estebancorral5151]

@@ericomfg it is greenhouse gas which deprives oxygen for humans to breathe.

Hi, what size thickness Geomemberane should I use for this biodigester ?

How can I connect with your group? I am always looking out for such sustainable solutions which can change people's live

[@rtmproject]

hello, may i ask where did you buy the digester bag?

[@bobdebouwer7835]

You could easily make it yourself. Get edpm or pvc foil. Fold it double and you only have to glue 3 edges closed.

Can you proof that it has all nutrition for plants

[@kevincalcome]

the fertilizer has nitrogen phosphorous and potassium which all plants need

[@gu3610]

You can build this yourself. Just search biogas digester.
