Rendering, Tanning & Specialty Skins

Rendering Services

Rendering is an industrial process that stabilises, sterilises and separates animal by-products into two value added products – animal protein meal and rendered animal fat. The products are mostly used in the animal feed industry, pet food, biofuels and oleo chemical industry. 

Wallace Group currently operate rendering plants in Waitoa, Washdyke, Hororata, Dunedin and Silverstream which all support our food processing partners and local farmers across New Zealand.

Wallace Group efficiently and safely process animal by-products from animals farmed for the production of food.

Wallace Group monitor raw materials and finished products to ensure that agreed specifications are being met. Processing is carried out in accordance with a risk management plan, which is verified and audited by the Ministry for Primary Industries. The plant also operates in line with the New Zealand Rendering Code of Practice.

Tannery Services

The Wallace Group Tannery was established in 1992 primarily to take advantage of the supply of casualty calves and cows collected. Since that time the Company has expanded its collection area so that it now services the greater North Island, as well as Canterbury and Otago.

Approximately 25% of the wet/blue Tannery production is made up of casualty calves and cows, with the balance being hides from meat processing plants.

Wallace Group has the technical expertise and equipment to process from the lightest slink skins up to the heaviest bull and ox hides. With a dedicated and skilled labour force of more than 100 at the peak of the season, the tanning operation produces a consistent quality product which is demanded and recognised by its customers worldwide.

Tannery Process Areas

Pre Treatment

Wallace Group processes significant numbers of hides each year. All hides are washed and preserved before the fat and flesh is removed. Most hides are tanned, with the remainder being salted.


In 2009 Wallace Group installed six new vessels to process calf skins into parchment. The hair is removed from the calf skins by liming them before they are hung to dry, ready for export.

Parchment is used by traditional Jewish rabbi for Torah scrolls and other important documents.


After tanning or salting, hides are graded accordingly to weight and defects. Our main markets are Europe and Asia.

‘Wet Blue’ cow hides are used for upholstery, shoes and handbags, while calf skins are used for shoes or garments.

Calf and Lamb Skins

Wallace Group processes around 600,000 calf skins and 450,000 lamb skins every season across its Waitoa and Feilding plants.

Skins are processes into high quality ‘Wet Blue’ or ‘Wet Salted’ skins, depending upon international demand.

Beam House

This is where the chemical processing to remove the hair and unwanted proteins from within the hide takes place.

Chrome sulphate is the main chemical used in the tanning of the hide:  this gives the hide its blue colour, and is the reason a tanned hide is referred to as a ‘Wet Blue’ hide.

Casualty Cow Collection

The collection of casualty stock is the environmentally sound way of protecting our valuable waterways. If it were not for the collection and recycling efforts of renderers, mountains of organic waste materials would create an immense environmental problem. Learn more about this service here.
