SFP Group

1What does SFP Group do?
SFP Group focuses on producing sustainable, green fuels and thus wants to contribute to a circular economy.
2Who is behind SFP Group?
SFP Group was founded by Erik Brouwer and Niels Peters.
3How does SFP Group produce sustainable fuels?
Biogas is initially produced by fermenting organic residual flows. Biogas is then upgraded to green gas; green gas is liquefied into bio-LNG.
4Where is SFP Group located?
SFP Group has production locations in Zeeland, Friesland and Groningen. The head office is located in Berlikum, Friesland.

SFP Friesland

1Where will the installation be built?
The location for the construction of the installation is in the Nieuwe Industriehaven on the Lange Lijnbaan in Harlingen.
2Why at this location?
The location is convenient. Transport by water and road is optimally arranged. In addition, potential buyers are a short distance away and suppliers of biomass are nearby.
3When will the construction of the installations start?
We expect to start construction with the installation in 2022 so that we are ready for production in 2023.
4How long will construction take?
The expected construction period is more than a year.
5Are local entrepreneurs involved in the construction?
We aim to use local businesses as much as possible. A number of (important) suppliers are located a stone's throw from our location. Local entrepreneurs are important to us, partly in view of the future (service, maintenance, speed).
6Is the construction of the installation sustainable?
The installation will be built on the basis of the latest, proven sustainable techniques. For example, solar energy (solar panels), optimal insulation and sustainable materials will be used.
7When will the actual production start?
Production will start in 2023. The installation is expected to be in full production after approximately 6 months.
8What is ultimately produced?
In the installation, organic residual flows are processed into an extremely sustainable fuel, bio-LNG. This is a liquid gas with a sustainable origin.
9What is the importance for Harlingen and Friesland?
Harlingen and the province of Friesland have the ambition to be a sustainable city and province. The UNESCO world heritage "the Wadden Sea" plays a prominent role in this. By producing bioLNG here and also using it (ferry service), Harlingen is put on the map. It will be the first port in the Netherlands and Europe to offer bioLNG in this way.
10Impact on employment, how many employees/staff?
Work will be offered immediately to 7 employees (including management). Indirectly (ie including suppliers) it will provide structural work for approximately 30 FTEs. During construction there will be 50 -75 FTEs.

Bio-LNG Installations

1What is bio-LNG?
Bio-LNG is a very sustainable fuel. "LNG" is the abbreviation for "Liquified Natural Gas" which means that the gas has been liquefied. "Bio" as an addition indicates that the liquefied gas is made from renewable, organic material. SFP makes biogas from organic residual flows. So no use is made of fossil natural gas, as is the case with LNG. Our biogas is made from everything that is on the ground and is therefore not a gas that is extracted from the ground. We close the loop.
2What is bio-LNG used for?
Bio-LNG is used as a fuel for heavy transport such as trucks and shipping. Renewable energy in the form of electricity, for example, is not possible in this sector. This has to do with the distance in relation to the consumption. Bio-LNG is therefore the best replacement for fossil fuels such as diesel. The bio-LNG is made available via the regular infrastructure for LNG, at filling stations.
3How is bio-LNG produced?
Initially, biogas is made from the organic material through fermentation. The biogas is then upgraded to green gas. Green gas is eventually cooled to -162 ⁰C, making the gas liquid. This reduces the volume by a factor of 600. This makes it possible to use bio-LNG as fuel for trucks, for example. In addition, it is much less dangerous than regular gas (volatile). This makes it very suitable for heavy transport (trucks & shipping).
4What residual material is used?
In Friesland, only vegetable bio-based materials are used. These are residual flows that can no longer be used in food and/or animal feed production. This includes residual flows from arable farming, (greenhouse) horticulture and rejected animal feed products. In Zeeland we also use animal manure. Under no circumstances does SFP process woody residual flows.
5Where do these organic residual flows come from?
In order to make the process as efficient and circular as possible, everything is purchased locally as much as possible. This prevents unnecessary transport. SFP has its own covered storage capacity.
6How does fermentation work?
The organic residual flows are collected in concrete, closed tanks. On average, the residual flows stay in these tanks for 60 days, during which time bacteria convert the organic components into methane and CO2. This is called biogas. This process takes place without oxygen (anaerobic). The residual flows are stirred in the tanks using mixers, so that it is liquid and the bacteria can optimally convert the residual flows into energy.
7Can you use everything to ferment?
No, you can't just use everything. There are extensive regulations about what can and cannot be used for fermentation. These rules are strictly observed so that the continuity of the company is guaranteed.
8Does household waste (GFT) go in?
Household waste is not used. Only legally permitted residual flows that are no longer used in the food and/or animal feed industry are used.
9What are the residual products from bio-LNG production?
CO2 is also released during the production of bioLNG. In fact, this is bioCO2. This is stored and used in, for example, greenhouse horticulture, but also in the food industry. In addition, digestate remains after fermentation. This is processed into a biological soil improver and is used in the agricultural sector as a replacement for fertilizer.
10Are organic residual flows also incinerated?
No, SFP only produces biogas (as an intermediate product for the production of bioLNG) by fermenting easily digestible, organic residual flows. This is a natural process. SFP does not use woody (bio)mass, but only 100% non-woody organic waste streams.
11What is so environmentally friendly about this fuel?
The use of bioLNG ensures that CO2 emissions in heavy transport (freight transport by road and water) are reduced by approximately 98% compared to fuel oil and/or diesel. In addition, the production of bioLNG is circular, it concerns renewable energy that creates a cycle.

Organic Fertilizers

1What is meant by organic fertilizers?
Organic fertilizer is a soil improver, consisting of valuable minerals. The organic fertilizers are extracted from digestate (the by-product of biogas production).
2How is the organic fertilizer produced?
The remainder of the biogas production is called digestate and is a valuable substitute for fertilizer. By separating the digestate into a thick and thin fraction, you can produce high-quality fertilizer.
3What is the application of organic fertilizers?
The fertilizer is used as a soil improver in the agricultural sector. This fertilizer replaces artificial fertilizer and thus also closes the cycle. After all, biogas production is based on residual flows from the same sector. The production of fertilizer uses a lot of natural gas, making organic fertilizers a sustainable alternative.

Environment & Risks

1How are raw materials and end product transported?
Raw materials can be supplied by water as well as by trucks. The end product (bio-LNG) is stored and then transported by tanker. The digestate, the end product that remains after fermentation, is upgraded to a sustainable, vegetable fertilizer. We expect to be able to ferment approximately up to 300,000 tons of vegetable biomass. This is comparable to 150 inland vessels.
2How much freight traffic around the installation, at what times?
The opening hours of the location will only be on weekdays from 06:00 to 20:00. During the weekend there is production, but there are hardly any transport movements.
3Pavement/concrete on site (due to noise)?
All sites are or will be asphalted. Inside, the buildings are provided with concrete floors.
4Are harmful substances released during the production process?
The biogas production process is carried out in oxygen-free and closed silos. The processing hall, in which the biomass is unloaded and stored, is equipped with underpressure. All areas are extracted and the air is exhausted through air scrubbers and a bio-bed. In this way, processes from which odors can arise are treated and there will be no odor nuisance.
5Does the installation cause air pollution/harmful emissions?
No, there are no emissions of harmful substances and gases. Biogas consists of methane (CH4) and CO2. The methane is completely converted to Bio-LNG and the CO2 is completely converted into liquid, 'food-grade' CO2.
6What could go wrong?
The installation has been designed on the basis of our knowledge, expertise and experience, whereby the possible risks that could be present have been minimized. A lot of redundancy and security are built into the installation and there are clear instructions for staff and visitors. In addition, all required laws and regulations in this regard are complied with.
7What are the consequences if things go wrong (for the environment and the environment)?
Due to the built-in safety checks and construction of the installation, a possible calamity will have little or no impact on the surroundings and the environment.
8Is fuel storage dangerous?
Bio-LNG is colorless, odorless, non-flammable or toxic. The bio-LNG in the storage tanks is inert and can therefore neither explode nor burn.
9Do the fermenters cause odor nuisance?
The tanks, in which the fermentation process takes place, are completely closed. The tanks are fitted with a concrete roof, which eliminates the risk of odor leakage. The products we use are all stored in a locked building. Any air that may be present in the building is continuously extracted and cleaned via an air scrubber. This prevents unpleasant odors. We already work in this way at our location in Zeeland, which satisfies the environment.
10Is it possible to refuel (as with LPG) / will there also be a filling station?
The bio-LNG is bunkered in an LNG storage tank/silo. The storage silo will be 'emptied' several times a week by the customer, who will then transport it to a tank location. It is therefore not possible to refuel at our locations.
