Polem composite silo for starch storage in Lithuania
A Polem silo type SKS 7/30/80 was delivered from Lemmer via SRP-Europe to a customer in Lithuania. The silo is used for storing dry starch and is designed for a bulk density of 700 kg/m³. Filling takes place centrally via the roof.
Five new Polem silos in Spoordonk
We recently supplied five new silos to a pig farm in Spoordonk: one measuring 20 m³, two measuring 40 m³, and two measuring no less than 54 m³. They look great next to the new barn – ready for years of reliable storage.Seamless, strong, and smooth as glass. That's Polem quality.
Summer wrap-up: this was Polem this summer
Summer 2025 is almost over. As the first autumn breeze makes its appearance, we at Polem look back on a summer full of craftsmanship, down-to-earth pride, sunshine, and surprising content. No quiet season for us – we stayed fully active.Below is a brief overview of this summer's highlights:1. Composite: the best choice even in the heat We kicked off July with a spotlight on insulation. Because even at 30+ degrees, our silos stay cool inside. Composite = stable, even in extreme temperatures.2. Animal feed storage? Top condition guaranteed From corn to compound feed: with a Polem silo you keep everything dry, fresh and lump-free. We explained how smooth walls and smart hoppers make the difference.3. Salt in July? Absolutely. Planning ahead pays off. In our whitepaper and blog, we called on municipalities and contractors to start working on their winter supplies now. Result: plenty of Expert Check requests.4. Expert Check: summer = planning season Our summer post "Vacation for your silo? Not at all." struck the right chord. Smart companies plan maintenance before it's necessary. Many checks are now scheduled for after the construction holiday.5. Skûtsjesilen & silos: Frisian pride on and off the water From our location in Lemmer, we had a live view of the Skûtsjesilen. We brought it together in a summer blog about precision, balance, and connection to our region.6. Cleaning without hassle Hygiene is top priority in food & feed. With composite, cleaning is no hassle: fewer residues, less water, less downtime. Simplicity pays off.What's coming up?This autumn we'll start with new customer casesWe're launching content about silos for the chemical and food industriesAnd... we'll naturally continue focusing on service, innovations, and international growthThis weekend in Lemmer: Glemmer Beach FestivalFinally: are you coming to Lemmer this weekend?

Sustainable choices from day one: SFP Groningen B.V. invests in composite storage tanks for new biogas plant
Reliability starts with the foundation. This was the guiding principle for SFP Groningen B.V. when developing their new biogas plant in Farmsum. Already in the design phase, they deliberately chose four high-quality composite storage tanks from Polem – a strategic choice for a future-proof installation.Project overview: Farmsum biogas plantA completely new biogas plant is currently being constructed in Farmsum, which will become operational by mid-2025. SFP Groningen B.V. centered their approach around four core values: safety, sustainability, ease of maintenance, and reliability.The storage capacity was filled with:2 composite tanks of 272 m³2 composite tanks of 100 m³Equipped with fixed cage ladders and crossover platforms for safe accessFully tailored to the specific requirements of biogas productionThese tanks are specially designed for the challenges of the biogas sector: chemically resistant to aggressive substances, structurally strong, lightweight, and easy to inspect.Why composite is the smart choice for biogas plantsCorrosion resistance where it mattersBiogas plants work with aggressive substances such as organic acids, ammonia, and hydrogen sulfide. Where traditional materials quickly degrade, composite remains intact for years. This means fewer replacements and a lower total cost of ownership.Seamless quality, optimal hygieneThanks to the seamless and mirror-smooth composite interior wall, the stored material remains free from contamination. No bacterial breeding grounds or product buildup occur – essential for a stable biogas process.Minimal maintenance, maximum uptimeComposite requires virtually no maintenance and lasts for decades. The fixed access systems make inspection safe and easy to perform. More production time, fewer maintenance stops.Optimal space utilizationThe chosen volumes of 100 and 272 m³ provide sufficient storage capacity with a compact footprint – an important advantage in complex biogas installations where every square meter counts.From design to realization: a partnership that worksThe collaboration between Polem and SFP Groningen B.V. proceeded according to plan, without surprises or delays. Our experience with biogas installations and the modular construction of our tanks enabled efficient realization.From design to placement: the process went smoothly. And most importantly: we now have sustainable storage solutions that will serve us for years to come,states SFP Groningen B.V.Sustainable building: investing in the futureThose who choose high-quality materials already in the design phase build peace of mind and security.

Polem's Summer Hit: First-In-First-Out
Just like your favorite summer playlist, every silo has its own rhythm. And we know exactly which 'beat' works best for your product.Why mass flow has the perfect summer vibeThe sun is shining, temperatures are rising, and just as you enjoy a refreshing flow on your terrace, your product in the silo deserves the same smooth treatment. In summer, everything is about flow – and that certainly applies to your storage systems.At Polem, we're big fans of mass flow. Why? Because it's as reliable as your favorite summer hit: it always works, it makes you feel good, and you want it again and again.First-in-first-out: the golden rule of smart storagePicture this: you have a refrigerator full of fresh summer fruits. What do you do? Naturally, you use the oldest fruits first before they spoil. Exactly the same principle applies to your silo with mass flow.First-in-first-out means:The product that enters the silo first also comes out firstNo 'forgotten corners' where product remains stationaryAlways fresh quality, like a cooling lemonade on a hot dayWith mass flow, the entire product moves uniformly downward. Just like guests queuing politely for the swimming pool – everyone gets their turn, no pushing, no chaos.Why your flour and powder love this approachCleaner than a spotless swimming pool Mass flow creates a natural self-cleaning effect. The continuous movement of the product prevents residues from remaining in corners and seams. Your silo stays as fresh as a summer breeze.Reduced risk of clumping Just as you want to avoid lumps in your iced tea, mass flow prevents your flour or powder from caking. The uniform flow ensures everything stays beautifully loose – exactly as it should be.Efficiency that makes you sing With mass flow, you can be sure your product flows smoothly out of the silo. No blockages, no manual assistance needed – just pure, smooth flow. Perfect for when you want to enjoy your summer vacation without worrying about your production process.The secret is in the angle Not all silos are built the same. At Polem, we make the difference with our 40° hopper angle. This seemingly small technical choice has major consequences:40° → Perfect for flour, powder, sugar, and other food products60° → Better suited for abrasive products like fertilizerIt's like choosing the right swim ring for your children – it seems like a detail, but it makes the difference between fun and problems.The Polem promise: no summer slump in your processWhile others might experience a summer slump, we ensure your production process keeps running at full capacity. Our silos with mass flow offer:Constant flow - No interruptions, no stressPredictable quality - You know what you're gettingLess maintenance - More time for important mattersPremium results - Because you deserve the bestMore than just technology – it's your peace of mindA well-functioning silo is like a perfectly organized summer vacation: everything runs smoothly, you don't have to think about it, and you can enjoy the results.

On the terrace... thinking about silos?
A cooling perspective on composite silos during hot summer daysA cold iced tea in hand. View over the water. The sun high in the sky. Nothing for a moment. Or perhaps... something. A thought about silos.Why? Because even on such a scorching hot day, it's striking how cool a good design can stay. And that's when we think of composite silos from Polem.The heatwave in the yardWhile you enjoy the shade, your storage stands right in the sun. Temperatures rise above 30°C. The asphalt is too hot to walk on. And you wonder: how does my silo actually hold up in this heat?With many traditional storage systems, summer is a problem. Metal silos turn into ovens. The contents clump together. Condensation causes mold. Products lose their quality. And the cooling system? It runs overtime.Composite: the natural air conditioningWhere steel expands in heat, puts connections under stress and creates vapor, composite simply remains... cool. No condensation. No clumping. No extra cooling needed.The secret? Thermal insulation.Composite: λ = 0.17 W/m·KSteel: λ = ±50 W/m·KThat's 300 times less heat conduction. In other words: the heat stays outside, your product stays at temperature inside – without energy consumption.Case study: July in BrabantA compound feed producer in the south of the Netherlands told us about a hot week with temperatures above 30°C.Two silos next to each other: one steel, one Polem composite. Both filled with the same compound feed. After a week:Steel silo: condensation on the inner wall, clumping at the bottom, increased moisture contentPolem silo: dry product, perfect discharge, no quality lossThe investment in composite had almost paid for itself that week, according to the owner.Why composite makes the difference on hot daysTemperature stability Heat stays outside, coolness inside. Ideal for temperature-sensitive products.No condensation Insulation prevents temperature differences – and thus condensation. And with it, moisture problems or mold.Energy-efficient Less or no cooling needed = lower operational costs and a smaller ecological footprint.Product quality is maintained Whether it's flour, salt, feed or chemicals – your product remains in top condition.Less maintenance No expansion, no stresses in connections. Less wear, longer lifespan.More than just coolnessA Polem silo excels in more than just temperature control:Seamless and hygienic designMirror-smooth inner wallPerfect discharge, even in summerResistant to UV and thermal stressFlexible to adapt or expandThe summer test: do you recognize this?Do you experience problems in summer with:Condensation on the inner wallClumping of stored productHigh energy costs due to coolingQuality loss or mold formationThen it's time to switch to composite.Cool advice for hot daysShould storage also be refreshing? Then choose Polem. Seamless, strong, mirror-smooth – and summer cool.Our specialists are happy to think along with you. Whether it's a compact silo or an industrial installation, we deliver the right solution for your situation.Or design your silo directly via our configurator.Every grain. Every drop. Quality in, quality out.It's not a silo or tank. It's a Polem.
Did you know…? The Summer Edition of Polem
The sun is high in the sky. Everything feels just a bit lighter: clothes, conversations, calendars. But did you know this also applies to silos and tanks?Light in weight. Heavy in performance.Polem composite silos and tanks are up to 70% lighter than their steel counterparts. And you’ll notice the difference. In transport. In installation. And especially when the temperature rises above 30 degrees.Lightweight? Yes. But without compromise. Composite, or glass fibre reinforced plastic , is extremely strong, corrosion-resistant and low-maintenance. Ideal for summer. And every other season.Why lightweight is such a smart choice in summerFewer transport movements. Lighter silos and tanks mean you can transport more in one go. That saves trips, fuel and time. Just what you need when roads are hot and margins are tight.Easier installation. No or less heavy cranes required. Which means no hassle on hard-to-reach sites, whether in urban areas or tight production environments.Reduced foundation requirements. A lighter silo or tanks demands less from the ground. Perfect for soft soils, sand, or temporary installations. Like road salt storage before winter arrives.Better working conditions. High summer temperatures call for smart choices. Lightweight components are less physically demanding and faster to install. Good for safety, good for your planning.Sectors that benefitFood industry Time is money – and composite silos are installed faster than stainless steel. Their seamless, ultra-smooth inner walls make them ideal for hygienic storage.Animal feed Composite silos and tanks can be placed closer to existing buildings without exceeding static loads. That shortens feed lines and increases efficiency.Road salt When weather turns, time is critical. Composite salt silos or tanks are quick to install – and fully corrosion-resistant. That means decades of use, even in tough conditions.Industrial & chemical sectors Composite silos and tanks are perfect for compact sites and existing platforms. Less weight, more flexibility – with no loss of safety or durability.Technical benefits in hot weatherMinimal expansion. Unlike steel, composite barely expands in heat. That means fewer stresses on flanges, less maintenance, and no shifting or ‘working’ silo.Better insulation. Composite hardly conducts heat. The result: more stable internal temperatures. Great for temperature-sensitive products and energy savings.Reduced condensation. Thanks to its insulating properties, less condensation forms inside the silo. This helps prevent clumping and spoilage – especially important during humid summer periods.Light in weight. Heavy in benefits.Polem composite silos and tanks last 20 to 30 years with virtually no maintenance. Easy to clean, fully adaptable, and always ready for change – whether that’s relocation or reuse.And the best part? Less weight = a smaller environmental footprint. Fewer emissions during transport. Less energy in production. Longer lifespan with minimal waste.Ready to invest in smarter storage this summer?Contact our specialists. We’ll be happy to advise you on the best solution for your application.Polem – The Right Flow Since 1972 Every grain. Every drop. Quality in, quality out.
Why composite? That's why.
Choosing a silo or tank might seem simple. But those who truly delve into material choice, application and lifespan quickly realize: not every material is equal.At Polem, we have been working exclusively with composite for over 50 years. And we have good reasons for that. Composite isn't a buzzword, it's a thoughtful choice. For you, and for your process.No corrosionComposite is naturally resistant to corrosion. That makes it ideal for aggressive substances, humid environments and outdoor storage. Where steel or stainless steel will eventually rust, composite remains intact. Even without coating.Lightweight and strongComposite silos are up to 70% lighter than steel. That means: easier transport, lighter foundation, faster installation. And at the same time: incredibly strong and resistant to high loads.Insulating propertiesComposite has excellent thermal properties. It limits condensation formation and keeps the temperature in the silo more stable. Perfect for food safety and product quality.Seamless designOur silos and tanks are produced as one whole, without seams or welds. No weak spots, no leakage. A smooth wall from top to bottom.Hygienic and easy to cleanThe inner wall is mirror-smooth. That means: fewer product residues, less cleaning time, and less chance of contamination. In food & feed, that's pure profit.Less maintenance, longer lifespanComposite is low-maintenance. No rust treatment, no additional coatings, no annual repairs. Simply: years of reliable use, with minimal downtime and lower TCO.A Polem silo isn't an option. It's the solution.Our customers don't choose composite 'because they can'. They choose it because it's smarter. More reliable. More sustainable. And future-oriented.Whether you're active in food, feed, industry, chemicals or de-icing: composite is the material for modern storage solutions.Want to know more?Would you like to know how composite silos and tanks fit into your process?

Cleaning without hassle – composite makes it easy
In sectors where hygiene is crucial, every detail matters. Whether it's storing raw materials in the food industry or in the animal feed chain: a clean silo is essential for quality and safety.At Polem, we understand that. That's why we manufacture silos and tanks from composite. Not only strong and durable, but above all: easy to clean.Smooth inside. Clean by itself.What makes composite so suitable for applications where hygiene is important? Simple: the inner wall of our silos is seamless and mirror-smooth. As a result, much less product remains in the silo. Residues that can stick to other materials simply slide down here.Less dirt buildupNo seams or gapsFaster cleaningReduced water and detergent usageShorter downtime.Simplicity pays – literallyLess downtime = more profitEvery minute of cleaning is a minute that your process is down. In food and feed, those minutes add up. Thanks to the smooth wall structure of composite silos, you save up to 60% on cleaning time compared to steel or stainless steel (without special coatings). And that means:More productive hoursLower cleaning costsLess chance of contamination or product lossHow to clean a composite siloDepending on the industry and the stored product, there are different cleaning methods. Fortunately, composite is compatible with most common techniques:Dry cleaning (e.g., with brushes or air): fast, efficient and sufficient for dry substances like flour, grain or powderWet cleaning (high pressure or foam cleaning): suitable for applications with higher hygiene requirementsCIP (Cleaning in Place): for automated plants, composite is highly resistant to detergents and temperaturesUnsure about the right approach? Our service department or market specialist is happy to advise you.An investment in simplicityCleaning is often a hidden cost item in the management of silos and tanks. By choosing composite, you make a smart choice that pays off in the long term. Fewer actions. Fewer risks. More control.Done with scrubbing? Time for composite.Want to spend less time on maintenance?
