Because biogas plant silage storage is one of the least discussed components of anaerobic digestion, we provide you our top Silage Clamp Tips here. It is, nonetheless, critical. It serves as a feed storage facility at periods when other feedstocks are scarce. However, for a good clamp operation, every silage clamp requires a great deal of attention. So keep reading for our Top 12 Silage Clamp Success Tips, including how to utilise clamps to store Biogas Digester Feedstock.
The ability to feed the digester every day of the year is something that every digester operator need.
The most important thing is to use a sturdy silage clamp.
The difference between a lucrative crop-waste-based biogas plant and a liability can be determined by silage success.
Top 12 Silage Clamp Recommendations
We share our top dozen silage clamp suggestions in the video posted on this page. In compliance with the Defra SSAFO requirements, here is some top advice for the safe and legal storage of AD feedstock in the UK.
In the video above, and again below, each of the twelve suggestions is presented and explained. After watching our video presentation (see above), come back to learn more about Anaerobic Digestion Plant UK's SSAFO compatible silage clamps.
1. The UK silage clamp rules (SSAFO Regs (UK)) must be followed when designing and installing silage clamps.
2. Silage clamps with earth bank walls sunk into the field and no other means of sealing are not SSAFO compliant.
3. The weight of the machinery used to condense clamps nowadays is substantially greater than the weight that a traditional silage clamp can sustain. Many are currently being built to the same standards as they were when they were first built. Always utilise the most up-to-date design requirements while creating.
4. The most cost-effective silage wall heights, according to concrete retaining wall providers, are up to 3m. They may, however, supply 4m-high precast walls, which can be useful for bigger clamps especially those at anaerobic digestion facilities.
5. It's critical to select an oxygen barrier film/cover membrane that will adhere to the clamp's surface closely. This is necessary to avoid pockets of trapped air from accumulating on the top and shoulders of clamps, which can lead to considerable aerobic deterioration.
6. While feeding the digester, leaving clamps open at both ends increases the total footprint without providing any operational benefits.
7. Prior to sealing and consolidating, a layer of at least a grab depth of fresh grass can be placed on top of a whole crop (e.g. maize silage) filled clamp to increase silage quality.
8. Make every effort to keep your silage-making clamps, as well as any pipes and tanks, in good working order. In this approach, the need for costly dirty water cleanups can be avoided.
9. Regulatory fees paid by the UK Environment Agency (EA) are based on the expenses of monitoring each biogas facility and storage clamp. Avoiding non-compliance occurrences that might cause the regulator to designate a digester operation as requiring particular attention will reduce licencing payments.
10. Ensure that silage AgBags, which are a source of concern for the EA and might result in more AE inspections, are always secure, well-maintained, and in the proper position.
11. There's always the temptation to push that extra piece of silage into the silage pit/clamp, but doing so may be extremely dangerous since it can cause the surrounding walls or silage pit/clamp to collapse, especially if the grass is too wet.
12. Air stress during storage and exposure to air during feed-out both lower biogas output. Without using an additive, tests on seven days of feed-out exposure to air revealed that up to 17% of the methane potential of maize was lost.
