HPS Pigging Systems Reduce Carbon Footprint by Tonnes of Carbon Every Day
Liquid product recovery (“pigging”) systems are increasingly being used to recover the residual liquid from process pipelines. They’re an incredibly effective way to increase yields and capacity, save on waste treatment and disposal costs, speed up changeovers, decrease cross-contamination, plus much more.
Another major benefit of product recovery and pigging systems is that they improve environmental sustainability. This includes lowering carbon footprint.
This is reflected in a recent report from sustainability and energy consultancy Carbon-Zero.
According to the report, companies that pump liquids or wet products through a pipeline can reduce their carbon footprint by tonnes of carbon every day by using HPS pigging technology.
How Pigging Works
Pigging works by using a specialist projectile to recover, rather than waste, residual liquid in process pipelines, for example when there’s a changeover in products.
The projectile (the ‘pig’) has an interference fit. As the pig travels through the pipe, very little liquid can get past it. So, this enables the pig to recover practically all the product to its destination, instead of wasting it.
Tonnes of Carbon Dioxide Saved Daily
Pigging systems are used in a wide variety of sectors, industries, and applications.
Foods, beverages, confectionery, personal care, cosmetics, lubricants, pet food, homecare, paint, and coatings – the list goes on.
However, the Carbon-Zero report specifically focuses on water-based and solvent-based paint production as examples.
The report finds that approximately 2.6 tonnes of carbon dioxide equivalent are saved every time there’s a product changeover. This is compared to conventional flushing processes and in terms of equivalent carbon savings.
And with many companies using shared pipelines for different configurations of product, they make several changeovers every day.
The Problem with Conventional Flushing
Conventional line flushing is frequently used to remove residual liquid product remaining in the pipeline when changing from one product to another. This process often uses significant amounts of water, energy, and resources.
In addition, the flush water often goes down the drain at the end of the cycle, which is a considerable waste.
However, with a pigging system in place, a significant amount of carbon dioxide is saved every time there’s a product changeover.
The Carbon-Zero report also highlights that, even when accounting for the embodied carbon used in manufacturing the pigging system, the carbon payback periods are instant. In addition, savings of over 95% carbon emissions per changeover are achievable.
Lowering Carbon Footprint by Pigging
So, why is pigging technology more effective at reducing carbon in comparison to conventional flushing?
Because pigging recovers so much product from the pipe, it reduces the need for long and continuous water flushes between product transfers and changeovers. In this way, pigging reduces water use considerably.
Also, pigging technology cuts waste, decreases the use of CIP chemicals, and lowers related transport and disposal costs. So, pigging systems have a positive environmental impact, while offering significant carbon savings.
Additional Benefits of Pigging
In addition to the environmental benefits, pigging systems deliver a wide range of additional benefits to companies that pump liquids.
These benefits included higher product yields, increased capacity, faster changeover times, reduced downtime, minimized contamination and cross-contamination risks, improved productivity, and better margins.
That’s why pigging systems are increasingly being implemented in liquid processing plants throughout the world, especially in hygienic, sanitary, and other liquid processes.
Can Be Applied to All Sectors
Although the report by Carbon-Zero is based on carbon savings in paint production, the findings can be applied to all sectors that process liquids.
Essentially, for companies that pump liquids and wet products and implement a pigging system, the carbon savings are going to be high compared to the conventional flush process.

About us
If you pump or process liquid or wet product, HPS proven pigging technology will increase your yields, reduce waste, speed up changeovers, improve your environmental sustainability and save you time and money.
By saving product instead of wasting it, HPS systems give you a high return on investment year on year. You’ll also get further gains from improved operational efficiency, less water and CIP chemical usage, and lower waste disposal costs.
How It Works
HPS pigging systems propel a specially designed projectile (the pig) through your line. This recovers the residual product you would usually flush to waste. This recovered product is perfectly usable, so you can continue to process it, pack it or sell it along with the rest of the batch.
HPS systems typically recover over 99.5% of product in a full pipeline. Exactly how much this is in terms of value depends on several factors (pipe length, diameter, product cost etc) but it’s nearly always significant. Meaning payback on your investment is rapid.
Plus, by pigging your pipeline you’ll make CIP and flushing a lot quicker and easier. So changeovers are faster and you save on cleaning agents, water, flushing, energy and labour.
