How Companies that Process Liquids can be More Sustainable

Sustainability is at the forefront of just about every industry’s long-term commitment. The process industries, which range from food, confectionery and beverage manufacture to paints, coatings, industrial lubricants, homecare, household and personal care products, are no exception.

Carbon reductions, water reductions, and waste reductions are important parts of the environmental commitments of companies that process liquids.

One place that companies may find that they struggle to reduce their environmental impact is during the processing stage of production. A large amount of liquid can remain in pipelines during product changeovers. What is more, some types of product can cling to the sides of pipelines, requiring excessive amounts of flushing with water and chemicals to prepare the pipeline for the next product batch.

In industries where hygiene protocols are paramount, there is a need to ensure pipelines are clean before moving on to producing the next batch of product.

This is where HPS Product Recovery Solutions technology can help companies that process liquids to reach their environmental goals.

Pigging and sustainability

Concern for the environment has grown and companies are now subject to regulations on carbon emissions, the release of effluent into natural water sources, and waste going to landfill. Many companies have released statements and plans for how they will reduce their individual impact on the environment within the next five years, ten years, and so forth.

Therefore, companies looking to reach their environmental goals should consider investing in a high-quality pigging system (here’s more information on what is pigging).

Also known as liquid product recovery, pigging systems enable companies to reduce their water usage and lessen their carbon footprint.

Pigging systems are valuable to the environment because they enable companies to use measured amounts of water and chemicals, decreasing the amount of effluent and waste product being either released into the environment or transported to facilities for waste treatment.

The decrease in the amount of product that needs to be transferred to other facilities has a significant impact on the reduction of carbon being produced by transportation vehicles. Pigging also helps to decrease the amount of greenhouse gases that are produced during the manufacturing process. Water quantities can be reduced, reused, and recycled. Cleaning and CIP (clean in place) chemical quantities can be decreased. Electricity and gas usage can be decreased. And importantly, product can be processed and packaged rather than thrown away.

Companies have become especially keen to reduce their impact on the environment and their reputation amongst customer bases. The value of a product is not just based on performance but also on ethical value; having a hygienic and sanitary pipeline product recovery system is a highly ethical practice that benefits the environment and future generations of humans.

Specialist Pigging Systems

HPS provide a range of pigging systems that are compatible with a wide variety of products, processes, and pipelines.

Each HPS pigging solution is bespoke designed to our clients’ needs. Just about every factory and process is different, so we make sure we supply a system optimised for your individual system, as well as your precise requirements, goals, and objectives. Our dedicated team of process system experts will be able to help you identify the pigging system that will benefit you the most, be that by recommending a system that will prevent aeration or, depending on the scale of production, discussing the viability of having either a Rotomatrix Rotary Manifold or Automatrix Automatic Valve Manifold installed.

HPS are also able to provide you with a state-of-the-art pig detector and pig detection system, so you always know how your pigging system is functioning. The pig detectors are installed at strategic points along the pipeline and indicate to the control system the appropriate time to speed up and slow down the pig.

Why Choose HPS

The primary goals of an HPS pigging system are usually to reduce waste, increase yields and capacity, and save money.

The HPS product recovery system enables up to 99.5% of the residual product that remains in the pipelines at the end of a batch to be recovered. By pushing the HPS sanitary pig through the pipeline, the product remains uncontaminated and can either be sent on for further processing, stored or packaged.

The HPS pig is unique on the market because of its design. It maintains contact with the pipeline constantly, even when going around sharp bends, ensuring that as much product as possible is recovered.

Our pig is sanitary and is compatible with clean-in-place procedures. It is constructed from FDA approved material, with a flexible magnetic core that enables optimum product recovery. The lack of fins on the HPS pig means that there is minimal risk of the pig chipping or breaking and contaminating the product within the pipeline.

How much product are you currently having to send to waste because you need to flush it out with water and chemicals?

Most of that product can be saved. It can be processed. It can be packaged. It can be sold.
