Biogas plant Modell 1: with storage bags

Summary
Environmental and agricultural scientist Katrin Pütz (Germany) developed her own small biogas plant with compost recycling in storage bags while working in development aid in Africa. She now applies this model for her own house with a garden. The only requirement is a certain amount of biomass and some water per day to keep the fermentation process running. In times of energy shortages in Germany under Scholz, Baerbock, and Habeck, she also sells the mini biogas plant with storage bags in Germany, along with instructions, for 550 euros.

Building a house with wood, straw, and clay including solar panels and a biogas system with storage bags
Katrin Pütz, together with her sisters, is building her own organic house made of wood, straw, and clay (52''). On the roof are solar panels, and in the garden, under a curved foil roof, is the central gas bag with the gas production from the biogas system:

Into this biogas system, bio-waste along with dishwater is poured in there, which is broken down by anaerobic bacteria using a portion of cow dung, thus producing the biogas. Under the bag is a heating blanket powered by solar electricity from the house roof. The gas bag should be fed every day. If you don't feed it again, the gas simply won't be produced. The bacteria remain present (2'25'').

Under the gas bag where the fermentation takes place, a heating pad is installed, because fermentation requires warmth [10] -

Water pipes and gas stove
Between the gas bag and the house, a water hose is installed. The biogas system in the garden is practically pressure-free; it is an almost non-pressurized system, so the gas can also flow through normal water pipes from the hardware store (2'47''). The gas pipe with the biogas goes through a gas meter into a storage bag under the house. From the storage bag, a gas pipe leads to the gas stove, and this way you can cook with your OWN biogas (3'29''). Enjoy cooking with your own biogas (3'34'').

[It should be possible to produce electricity with the gas, and in this way, the biogas plant would be independent of solar power].

The development of the home biogas plant with storage bags in Africa
[In hot countries, no electricity is needed. The warmth is doing the work].

Ms. Katrin Pütz first developed this home biogas plant for Africa and now also sells the system in Germany because "energy poverty is right on the doorstep" [or let's say like this: because the Green Party's Baerbock and Hahahahabeck want a Stone Age Germany]. There, larger biogas producers can also sell storage bags filled with biogas (3'51''). Katrin Pütz developed the biogas backpack so that people can buy and transport biogas on foot. People with a lot of organic waste can also produce biogas for their neighbors and thus generate income with biogas (4'19'').

Official development aid is inefficient
Official development aid gives away free biogas plants in Africa, but they are not efficient [because only those people who have a lot of organic waste can produce a lot of biogas]. For this reason, Katrin Pütz is in contact with African activists to keep the biogas system running - AGAINST official development aid, which wants to destroy it (4'45'').

Ms. Katrin Pütz also sells her mini-biogas plant along with training in Germany [where energy is needed for the warmth of fermentation] (4'50'').

The residual fertilizer ("digestate")
Another product of biogas production is the liquid, organic residual fertilizer ("digestate"), which is poured into the garden or onto raised beds (5'13'').

Katrin Pütz's mini-biogas plant along with instructions is being sold for 550 euros (5'32'').

The biogas backpack (gas storage backpack) - patent from 2011

Quote (translation):

The biogas backpack is a gas-tight bag equipped with a gas connection and carrying straps. It can be filled with biogas [without pressure] and transported.

Ms. Katrin Pütz was a student at Hohenheim University (near Stuttgart - link) making her doctoral tesis for becoming an agrarian engineer working out this principle [of the gas storage backpack]. With the Institute of Agricultural Engineering in collaboration with the University of Addis Ababa (link), she developed this principle up to an item for the market [1]. Since 2011, the biogas backpack has been patented [2] which makes biogas transports in the countryside possible from biogas plants to the home. Biogas plants can sell in this way their surpluses from their plants. So, this biogas can replace wood for cooking which is a great advantage for preserving ecological resources, for saving eyes and lungs from damage by steam and gases during cooking with wood or coal.

The backpack is made of multiple layers of plastic, which are welded and stitched together. With a length of two meters and a weight of four kilograms, it holds one cubic meter of biogas. This amount is sufficient for the daily needs of a family. To operate a gas stove, the biogas backpack must be connected with a hose and there must be put a weight on the sack [for producing a little bit of pressure]. Since the backpack is filled without pressure, there is no risk of explosion. Even if the entire backpack ignites, it burns in a controlled manner. The biogas backpack has been tested by the German Product Control "TÜV" and the Ethiopian "ECAE" and found to be safe. The backpack is sold locally by independent licensees and business partners at the usual market prices in their respective regions. This prevents interference with other products on the market, which is often the case with donated development aid, but still opens up a business opportunity for entrepreneurs in terms of development cooperation.
