From North America's first continuous rendering plant to today's wide range of rendering installations worldwide, Dupps has pioneered innovations in the protein recycling industry. Whether your needs require a complete system renovation or an upgrade to a single piece of equipment, Dupps engineering experience is ready to keep your operation running at peak efficiency.

To better support rendering facilities across the globe, we're committed to bringing the very latest design, manufacturing and quality control technology to our own facilities. The result has been rapid introduction of innovative new products, faster delivery of vital maintenance parts and continued high quality.


Examples of recent engineering innovations include a patented process for manufacturing bi-metallic hard-surfaced Tuff-Cast™ screw press flights that increases screw press shaft life well beyond any other flight on the market. The new Hybrid HCPR™ screw press shaft can extract more fat by dramatically lowering residuals in most rendered products.
