My remark was about "easily accessible" waste ... (for the average person: it is easier to find grass than grease ...)


... but less than manure!

Yes, more accessible, but at the same time extremely seasonal!

Methanisation: the government sets a ceiling on food crops

AFP on July 08 2016

Anaerobic digestion plants can now only use a maximum of 15% of food crops (cereals, oilseeds, etc.) specially grown for energy use, in their supply of raw materials, according to a decree published in the Official Journal on Friday.

According to this text, which stems from the law on energy transition passed in August 2015, anaerobic digestion facilities "can be supplied by food or energy crops, grown as the main crop, in a maximum proportion of 15% of the gross tonnage. total inputs per calendar year ". This text will enter into force from January 1, 2017.

When "whey" turns into energy

When “whey” turns into energy Specializing in the processing and recovery of liquid and solid by-products for the food industry, the Valbio engineering company of the Valgo group offers to transform milk residues into energy. A good way to achieve energy independence for a site, and to develop all of the milk by-products, without waste.

July 08, 2016 batiweb.com

Faced with the steady fall in milk prices, players in the dairy and cheese industry are looking for alternatives to enhance their entire production, at a lower cost.
“Thirty years ago, milk residues also called“ whey ”or whey were used to feed pigs. This residue may also be dried in one of two large French units, based in the north of France, to make a powder intended for animal feed. However, this often generates additional transport costs and is not necessarily profitable, ”underlines François Decker, Deputy CEO of Valbio.
This is why this company, which specializes in the processing and recovery of liquid and solid by-products for the food industry, simply offers to make energy out of it through its newHey offer.
“First of all, we promote this“ whey ”, by producing new derived dairy products, such as ricotta, crème fraîche, butter or even protein powder. This creates real added value. What cannot be reused is then redirected to the methanisation unit, ”specifies François Decker, who had to“ adapt the technology to this complex product ”.

In the methanizer, the remaining liquid, sweet and charged with microorganisms, will transform under the action of bacteria into biogas, rich in methane. The unit - having two patents - allows with biological treatment, to obtain a purifying yield of 99%. The treated water can then be discharged into the natural environment, without the risk of pollution.
"Compared to a conventional treatment station, electricity consumption is divided by 10 and the formation of sludge by 5, which makes it an economical treatment solution", underlines François Decker.
Electricity production of 1 inhabitants

Last year, Valbio set up its largest unit of this type in Alberville in 2015 for the Union des Producteurs de Beaufort.

Called Savoy Milky, the plant processes 200 liters of whey every day, or 000 million liters per year, and the site produces 55 million KWh per year - the equivalent of the electricity consumption of 3 inhabitants.
"Newhey will allow milk and cheese producers to expand their production and open up new commercial outlets, while becoming producers of green energy, 100% renewable", says François Decker.

This offer also has good potential for the years to come. “We believe that the French market will develop, because our offer makes it possible to give autonomy to manufacturers and producers. In numbers, this could translate into the establishment of a hundred units in Europe, "advises the Deputy CEO cautiously.
The company does not focus solely on the French market. It has already set up around twenty methanisation units in Canada between 2008 and 2011 "a country which cares more for the environment than the cost of energy, inexpensive" and will install a first unit in Chile next October " where access to energy is difficult ”.

METHELEC, the largest agricultural methanization unit in France

Posted by Frédéric DOUARD on November 25, 2016

Several hundred visitors attended the METHELEC inauguration on October 5, 2016 and were able to discover this multi-energy site located on a Limagne farm. Coupled with the production of photovoltaic energy, the METHELEC anaerobic digestion unit is the largest agricultural anaerobic digestion unit in France.

Developed by the LHOSPITALLIER family, a farmer based in the town of Ennezat in Puy-de-Dôme, the project has been since 2012 co-developed with the LANGA group, an independent producer of renewable energy. The project consists of producing biogas by treating livestock effluents and waste from local food industries.

Méthelec uses 36 tonnes of biomass annually, more than 000% of which is from farm effluents or by-products from the farm or neighboring farms.. The balance of biomass comes mainly from the surrounding food industries. To do this, the unit has the X-line® incorporation line, exclusive to XERGI installations, which allows it to anaerobic digestion of manure and other plant biomass in large quantities. The installation performs total biomass hygiene using the FlexFeed® system coupled with an exclusive energy recovery system.

Panorama of renewable gas in 2016

22 Feb 2017 Dorothée Laperche actu-environnement.com

With a jump of + 162% in the injection of biomethane into the network, the sector seems to be flourishing. However, this figure should be put into perspective: production represents only 0,05% of French consumption. State of play of actors and perspectives.

Injection has the advantage of making better use of gas, because cogeneration does not always find an outlet for heat ...

But it has the disadvantage of only being profitable for fairly large units - hence a tendency towards concentration. Whereas a territorial network would optimize the system by reducing transport ... Of course, this does not play a role when the installation is linked to a huge WWTP, which already "concentrates" the biomass by nature ...

Brittany launches its largest bio-methane unit

By Frédéric De Monicault on 08/03/2017

The Vol-V group commissioned the Guelen power plant in Finistère on Friday. It will cover the equivalent of the gas needs of 10% of the population of Quimper.

Little by little, the bio-methane sector is pushing its pawns in France. Admittedly, green gas still represents less than 1% of gas consumption in France, but it can be based on a number of developments. As proof, the Vol-V group, specialized in renewable energies, inaugurated the largest bio-methane unit in the Great West on Friday. It is located precisely in the Guelen activity area, in Finistère, near Quimper. The production target displayed ranges from 2 to 2,5 million cubic meters injected into the GRDF network per year: these volumes are directly intended for local consumption. In comparison, these deliveries represent the equivalent of the gas consumption of 6 people, or around 350% of the population of Quimper.

"This project is fully in line with the energy transition, with a production loop which illustrates well the circuits of the circular economy," explains Cédric de Saint-Jouan, president of Vol-V. Thus the nine farmers who are partners of the installation contribute almost 50% to the supply of the bio-methane unit with substrates. ”These substrates are all vegetable raw materials which, in the context of a natural chemical reaction, produce energy. The farmers in question are located within a radius of 7,5 kilometers around the power plant. Their farms - cattle, pig and poultry farms - cover an area of ​​almost 2 hectares.

Bus fleet

Cédric de Saint-Jouan also recalls that his teams traveled throughout Breton territory in 2011 to find the territory most suitable for the future installation. "The Quimper region had all of the advantages that the bio-methane sector is looking for in general," explains the interested party, "namely the presence of industrialists in the agro-food sector producing methanisable waste, the proximity of farms, the agglomeration’s commitment to the energy transition and its gas-powered public transport system. ”Quimper has a fleet of gas-powered buses and, still by way of comparison, the production of Guelen power station will produce twice the equivalent of the annual consumption of this fleet.

Finally, it should be noted that Vo-V development projects are not limited to Brittany. Currently, four biogas plants are under construction in France, including units in Normandy and Beauce. "By 2021, we have the ambition to become the leading producer of bio-methane in France with a target of more than 0,5 terawatt hours (TWh)", concludes Cédric de Saint-Jouan.
