Plantbased Raw Materials International (PRM) is a cooperative focusing on increasing the value of alien plants and organic waste. We have a different view on organic waste. We see organic waste as a potential raw material for bio-based products, animal feed and food. We organise value chains to upcycle plant fibres and protein into sustainable products and goods. These new value chains create jobs, support community development, and reduce the environmental and social problems associated with alien plants and organic waste streams.

Who we are

Complementary strengths

PRM is a partnership that combines the complementary strengths of its founding partners to find financially sound solutions for some of society’s largest problems. We are blue economy adapts. We think that our traditional take-make-waste mentality will come to an end and will be replaced by a more circular view on the way how we produce, use and reuse.

Our mission

PRM International acts as a change agent towards a biobased and circular economy. We develop integrated value chains for biobased products and solutions in communities and regions.

Our vision

To transform large-scale ecological and societal problems associated with (invasive) water plants into biobased business opportunities.

What we do

Igniting a new way of thinking

We advise municipalities struggling with the uncontrolled growth of different plants. We take stock of the local situation, analyse plant characteristics and qualities and come up with possible business models.

Customizing our business model

For projects facing problems with overgrowth of plants we created a business model based on cooperation throughout the entire value chain: from problem owner to executive organization and from biomass processor to bio/based producer. This business model is applicable in different countries with similar issues. After we consulted the municipality and analysed plant characteristics we customize our business model to the local situation.


All stakeholders are part of the process of implementing the business model. Implementation comprises three phases:

1. Harvesting the plant

This concerns the organisation and implementation of the harvesting and drying process. Harvesting methods and drying locations will be optimised in line with the type of plants and the local situation.

2. Market research product opportunities and sales market

We test the quality of the plant as a raw material and we develop the recipe. We also look into other organic (waste) streams to achieve an optimal blend. We assess local demand for potential end-products and decide on a limited number of product-market fits.

3. Processing plants into products

In this stage the plants will be processed into end products. We partner with a production- and sales company to bring the products to market and we set up a Fibre Application Center to further develop biobased products.

Benefits of our business model

Employment opportunities: production, distribution and sales

Quality improvement drinking water

Cost savings in water purification

Creating a market for products based on circular economy

Reducing problems with irrigation channels, hydroelectric power stations and in fishing- and watersport areas

Improving sustainability of the packaging industry, agriculture and other industries

Case: water hyacinths in eThekwini

The municipality of eThekwini is facing serious problems with the overgrowth of the water hyacinth. The plant causes large problems in the water quality of South Africa. PRM-International steps in to ignite a new way of thinking. Because in dried form, the plant can be used as raw material for packaging- and building materials and thus can play a role in sustainability on a commercial basis.

  • Uncontrolled growth of alien plants

    The story begins with a work visit of SPPS in the South African municipality of eThekwini. The municipality is facing an urgent problem with the overgrowth of water hyacinth.

    The effects of the water hyacinth are:

    • biodiversity destruction
    • oxygen depletion and reduced water quality
    • breeding grounds for pests and vectors
    • blockage of waterways

    Some water hyacinths grow up to 2 to 5 metres a day and double their population in two weeks. The invasiveness of the hyacinth is related to its ability to clone itself. Each plant can produce thousands of seeds each year and these seeds can remain viable for more than 28 years. An urgent issue that needs to be resolved.

    Sustainable solution

    eThekwini is looking for an affordable and structural solution. SPPS steps in to take the initiative for a commercial solution to the problem. Though SPPS has an extensive network of private and government contacts in this region, the company can’t solve the problem on its own. It’s being dependent on third parties.

    SPPS consulted Gido, a company that is working on a similar sustainability project in Holland. Together they approached Millvision and Ripple-A for their expertise in the project. This resulted in a shared conviction: together we can transform a large-scale social and business problem to an ecological and economic opportunity.

    From problem to opportunity

    Together we are aiming to conduct market research for a start up company that develops biomass based products, run a production facility and create access to the market. We investigate product opportunities and sales market. We organize a value chain: harvesting the plant, testing the quality and compatibility of the raw material, developing a recipe and developing and selling an end product.

    The water hyacinth can be used for:

    • bioenergy
    • treatment of waste water
    • medicinal use
    • furniture, handbags and rope
    • potential as bioherbicidal agent
    • potential for biobased products in packaging

    Mid-term goal: run a production- and sales company in cooperation with a local partner and set up a Fiber Application Center for further development of biobased products.

    Long-term goal: control the growth of the water hyacinth and upcycle the organic waste streams.
