Ecowood Wood Composite Compounds

Agriligna Raw Material

The use of wood in polymers is nothing new and has been used for many years as a cheap filler.  However, It was only during the past ten years that the use of wood as the primary ingredient in extrusion compounds started taking the stage.

Gone are the days of wood as a cheap filler, substituting polymer, and here are the days of extrudable and injection mouldable wood as a substitute for both traditional polymers, as well as natural wood.

The benefits of having an extrudable or injection mouldable wood is obvious in the savings in labour and machining costs, but even further than this, it opens up a whole new market to the polymer industry previously occupied almost exclusively by natural wood.

Starting in 1998, Agriligna set out to develop this technology using local expertise and patents in order to make these new exciting products available to the South African polymer industry.

In 2002 this dream became a reality with the start-up of the first plant to manufacture wood plastic composites (WPC) in Africa.

Today, with its plant in Modimolle (Nylstroom), Limpopo, Agriligna is one of the leading suppliers of wood plastic composites to the Southern African market - and manufacturer of Ecowood®profiles!

Currently Agriligna provides compounds for the following:



These compounds are primarily in pine colour, but other colours are also available.

Agriligna compounds contain between 50% and 75% natural fibre. Depending on the specific requirements of the end-product, various polymers can be used as the base for the composites, but in general patented crosslinked HDPE and PVC are used.

The material is sold as a basic compound to enable customers to do their own in-house development for their specific end-product requirements.  Agriligna collaborates closely with interested parties in the development of their particular products based on its own in-house capacity in this field.  In this regard Agriligna assists interested parties with:

Optimising the design of the product by taking into account the unique characteristics of WPC as a material,

Closely following the cost implications of the design, the WPC compound to be used and the particular conversion technique to be used in order to optimise the economics of the process,

Getting the dies or moulds made through manufacturers that Agriligna identified as reliable and competent,

Running experimental trials in-house on the Agriligna conversion equipment to test the dies and moulds,

Assisting clients of Agriligna’s compounds with the introduction pf the compound’s conversion on the client’s own equipment and the associated teething problems,

Following from its close collaboration with the Department of Mechanical Engineering of the  North West University, to design manufacture and commissioning of complete extrusion lines with all the necessary down-stream equipment  based on Agriligna’s in-house expertise.

In certain specific applications, Agriligna may consider entering into an exclusive minority equity basis with clients using the Agriligna compounds.

The use of waste renewable natural fibres also makes this deck a must for the environmentally conscious who care for the forests of the globe. This offers a decking material with inherent moisture repelling characteristics, which eventually leads to lower maintenance. The deck contains UV stabilisation to ensure a longer life in African conditions and the minimum maintenance.


Burial Caskets

A dome casket in raw form supplied as a flatpack with the four sides and two half dome lids. Finished caskets are trimmed and finished with conventional handles and linings. The construction also make the caskets suitable for cremation purposes. The ultimate solution for the casket manufacturer.


Bee Hives

The hives are based on standard Langstroth dimensions to seamlessly blend in with other hive components. Ecowood® bee hives are manufactured from the same enduring material as our decking. The hives are supplied in an easily assembled flat-pack form.


Door Frames

Ecowood® Door Frames are manufactured with a registered design profile that facilitates easy attachment to existing walls or building into a new wall. Factory fitted Hinges & Striker Plate. Move mouse pointer over door frame.


Wood Composite Extrusion Dies

We design, manufacture and supply extrusion tooling for wood composite profiles according to the highest manufacturing standards. All dies are run in our factory before despatch to any destination worldwide. The dies are shipped with a sample of the profile that was run on that die.
