As 2025 comes to a close, we’re taking a moment to look back at the content, conversations, and milestones that mattered most to HPS and the liquid processing industry this year.
From the topics manufacturers engaged with most to key moments for our business, here’s our HPS 2025 Wrapped.
Top 3 HPS Blogs of 2025
These were the most-read blogs on the HPS website this year, reflecting the challenges manufacturers are actively working to solve, from waste and product quality to cost pressures and efficiency.
1. How to Clean a Chocolate Transfer Pipe Using Product Recovery Pigging
This article saw particularly strong engagement from chocolate manufacturers. It explains how pigging removes residual chocolate from pipework before cleaning and changeovers, helping to reduce waste and product loss.
It also explains why traditional cleaning methods often fall short in chocolate production, where water can cause chocolate to seize or solidify, leading to waste and additional cost. The article also explores common alternatives and why these approaches are time-consuming, costly, or inefficient.
The blog then introduces hygienic pigging technology as a practical solution, showing how pigging can recover up to 99.5% of residual chocolate from pipelines before cleaning. By clearing the pipework effectively, pigging reduces the need for butter and oil, shortens changeovers, prevents product solidification, and keeps product from sitting stationary in the pipeline.
2. How Much Does a Pigging System Cost?
One of the most-read articles of the year, this blog tackles a common (and often misunderstood) question.
Rather than offering fixed prices, it explains why there is no such thing as a standard pigging system and how costs are determined by each customer’s process, requirements, and level of automation. It also outlines what’s typically included in a pigging project, the role of commissioning, and why pigging systems usually deliver high ROI with short payback periods.
The article finishes by explaining how to obtain a tailored quote or budgetary estimate, reinforcing that each system is designed around how the process actually operates.
3. Benefits of Pigging Systems for Food Companies
This article explains why pigging systems are widely used across the food industry to recover residual product from pipelines, helping manufacturers reduce waste and increase usable yield.
It also explores the wider operational benefits of pigging, including faster changeovers, reduced flushing, lower water and chemical use, and improved plant uptime. Together, these benefits make it easier for food manufacturers to manage shorter runs, growing SKU ranges, and increasing cost pressures.
Top 3 HPS LinkedIn Posts of 2025 (by Impressions)
Throughout 2025, our LinkedIn content focused on real projects, real results, and real challenges facing manufacturers. These three posts generated the highest engagement and impressions across the year.
1. Project on Its Way to the USA
This behind-the-scenes project update was our most viewed LinkedIn post of the year. It showcased a skid-mounted pigging system undergoing final testing before shipment to a chemical and consumer goods manufacturer in North America.
The post resonated strongly with our audience by highlighting:
- Real project delivery
- Pre-installation testing
- Collaboration with our valve partner Bardiani Valvole
The practical benefits of pigging, including improved yields, reduced waste, and lower cross-contamination risk
It was a great example of how transparency and real-world engineering content continues to drive engagement.
2. The Sweet Solution for Chocolate Producers
With cocoa prices at record highs, this post struck a chord with chocolate manufacturers under pressure to protect margins.
It highlighted:
- Pigging recovering up to 99.5% of product from pipelines
- Significant reductions in rework and flushing losses
- Real-world examples from UK and US chocolate producers
- Coverage in International Confectionery
The combination of industry context, real savings, and external media coverage helped make this one of our most shared and discussed posts of the year.
3. Project Spotlight: Cutting Waste & Costs with Pigging
This case-study-led post focused on a pet food manufacturer facing significant product losses due to material left in pipelines, amounting to over £4 million annually.
The post detailed:
- Product losses of up to 700 kg per batch on larger lines
- High water usage and disposal costs
- The impact of automated pigging on yield, waste reduction, and changeover time
The strong engagement reflected ongoing interest in measurable, operational improvements, particularly in high-volume food manufacturing.
Why These Posts Mattered
Across all three, the common theme was clear: manufacturers are looking for proven, practical ways to reduce waste, improve efficiency, and protect margins, without compromising quality or hygiene.
Top 3 Moments at HPS in 2025
Beyond content and campaigns, 2025 was a milestone year for HPS. Here are three highlights that shaped the year for our business and our team.
1. HPS Celebrated Its 30th Birthday
2025 marked 30 years of HPS, celebrating three decades of helping manufacturers recover product, reduce waste, and improve process efficiency. It was an important milestone that recognised our history, experience, and continued focus on innovation and engineering excellence.
2. Sunday Times Top 100 TECH Recognition
Being named in the Sunday Times Top 100 Tech was a proud moment for the entire HPS team. This recognition reflects our people, culture, and ongoing commitment to delivering high-quality solutions and support to manufacturers worldwide.
3. HPS Webinars
In 2025, HPS hosted a series of webinars focused on practical process challenges faced by manufacturers, including waste reduction, product recovery, and efficient pipeline design. These sessions allowed us to share technical expertise, real-world insights, and engage directly with manufacturers across food, beverage, and industrial sectors.
Looking Forward
The engagement across this year’s blogs, LinkedIn posts, and company updates highlights the topics manufacturers are focused on. reducing waste, protecting product value, and improving process efficiency.
Thank you to everyone who followed, read, attended a webinar, or engaged with HPS during 2025. We’ll continue sharing practical insight, real project examples, and technical expertise in the year ahead.
