Liquid product recovery (pigging) is in wide use by personal care, cosmetics, and homecare product manufacturers. It delivers an extremely attractive return on investment (ROI) with quick payback.

From Colgate Palmolive, L’Oréal and P&G to Unilever, Henkel and Clorox, pigging is helping these manufacturers increase yields, cut waste, speed up changeover times, and boost environmental performance.

How Pigging Systems Work

With raw material prices constantly fluctuating, competition increasing, margins getting tighter and the need to reduce waste and meet sustainability goals, manufacturers are realizing the significant cost savings and efficiency gains they can achieve by recovering product from their pipelines, instead of wasting it. In a wide range of industries that process liquids, pigging has become a must.

Sanitary (hygienic) pigging systems work by propelling a specialist projectile (the ‘pig’) through process pipelines. Because the pig fits tightly in the pipeline, it reclaims the liquid product that would otherwise be discarded during changeovers and cleaning.

Products that can be pigged include everything from deodorant, shower gel and moisturizer to detergent, washing up liquid, toothpaste, perfumes, and bleach. In fact, just about any product that can be pumped, can be pigged. However, the more valuable the product, the longer the pipework and the larger the diameter, the more there is for manufacturers to gain from pigging.
