The World Renderers Organisation (WRO) was founded in 1999 to represent the international rendering community. Rendering, known to be the world’s original recycling business, has been prominent in several civilisations for centuries. Processors from the USA, Canada, UK, Europe, Australia, and New Zealand established the WRO that now represents more than 20 countries. New country members are always welcome to join the organisation.

Following the BSE crisis in Europe in the1990’s, it became essential that renderers engage international regulators with one voice. WRO has become that voice in dialogue with OIE, WHO, FAO, and Codex Alimentarius.

WRO encourages a science-based regulatory framework that will permit the maximum utilisation of rendered animal products in a safe and sustainable manner. Education, research, and advocacy are important features of WRO.

Renderers will play a key role in the future in regard to climate-related issues, international economics, and closing the gap between food (human) and feed (animals) that provide real challenges. WRO members must be imaginative and innovative in their processing methods, and minimise energy use and waste in order to maximise opportunities.

Factoring into this is world population growth, declining natural fish resources, and the global energy situation with limited and costly resources. There is no doubt that now is the time to promote rendering as a responsible and prudent industry that is extraordinarily capable of playing an essential role in our planet’s future.

WRO members welcome you to this website and hope it will give you an opportunity to learn about our industry and understand how rendering can be part of a better tomorrow.


The vision of the WRO is to be the principal organization representing the interests of the rendering industry on a global level, serving as a vehicle for exchanging points of view on rendering issues and, where appropriate, to express positions to governments and world organizations.

The WRO will enhance the contribution of the global rendering industry in improving the environment and in meeting the growing global needs for feed, food, biofuel, and industrial raw materials in a sustainable manner, without adversely affecting the production of food for human consumption.



The WRO is the organization that represents the rendering industry worldwide, serving as an exchange platform for education and information amongst its members and with like-minded associations around the world. WRO represents its members in international government and world organization forums debating topics such as food production, animal and human health, and the environment.


Rendering is a process that stabilises, sterilizes, and separates animal by-products into two commodities – animal protein meal, often termed meat and bone meal (MBM) or processed animal protein (PAP), and rendered animal fat, such as tallow, lard, or grease. Renderers around the world efficiently and safely process animal by-products from animals farmed for the production of food and used cooking oils (UCO) from food processors and restaurants or from fallen stock from livestock farming.


  • Mobilize and represent the rendering industry at a global level; to be the voice and ears of the global rendering industry.
  • Promote, on behalf of its members, the interests and image of the global rendering industry by speaking at international events and publishing articles and research findings in appropriate publications and on the WRO website.
  • Provide information on the positive contribution of the rendering industry on the environment and the sustainability of its finished products.
  • Facilitate the international movement of animal fats and protein meals.
  • Compile and disseminate appropriate scientific research to its members, governments, and world organizations.
  • In order to achieve its mission, the WRO, through close co-operation with its members, allied organizations, and research institutions, will facilitate open communication with global organizations related to feed and food manufacture, including the OIE, FAO, WHO, and Codex Alimentarius.
