Upcycling Invasive Species: A Novel Biodegradable Alternative

Can two global issues be solved simultaneously? HyaPak, a Kenya-based startup, is proving that it is.

HyaPak converts water hyacinth, an invasive aquatic weed, into biodegradable alternatives to single-use plastics. In doing so, they address one urgent problem while helping to solve another.

A Class Trip that Inspired a Business

HyaPak’s story began during a class trip to Lake Naivasha, Kenya. During the visit, Joseph, the company’s founder, and his classmates got stuck in water hyacinth. That experience made him realize the severity of the problem and inspired him to seek a sustainable solution.

After much hard work, Joseph developed a product that tackles hyacinth infestation and reduces plastic waste. So far, it has been the most successful solution amid the endless and costly efforts to remove and dispose of this weed.

Creating Value across Multiple Sectors

One of the most impressive aspects of HyaPak’s strategy is its fully holistic approach:

“We clean the lakes while creating green jobs and reducing plastic waste pollution simultaneously,” said Joseph, HyaPak’s founder.

The company utilizes water hyacinth infestations as a “massive, renewable, and untapped resource” to reduce its reliance on petroleum derivatives. At the same time, it cuts plastic waste while creating a positive impact on local communities.

“We engage communities as active co-creators, not just beneficiaries,” Joseph added.

To date, HyaPak has created over 45 casual jobs and enabled the removal of hyacinth from more than 20 hectares of lake surface, directly improving navigability and restoring fishing grounds.

Transforming Hyacinth into Biopolymers

To achieve today’s impact, Joseph developed “an end-to-end system engineered specifically for the unique lignocellulosic structure of water hyacinth.”

The process currently includes three stages:

1. Drying and Preparation Phase: After harvesting the hyacinth, the team sundries it in the open. This method uses minimal energy and reduces costs. More importantly, it preserves the plant’s fibrous structure, which ensures the mechanical strength of the final material. Once dried, they crush the hyacinth into a uniform feedstock.
2. Material Development Stage: “This is the heart of our innovation,” Joseph said. The team applies proprietary methods to treat and break down the hyacinth while preserving the essential fibers. This step produces a high-quality, malleable pulp that forms a reliable base material.
3. Conversion Stage: Finally, they blend the hyacinth pulp with additives into a biopolymer matrix, then extrude it to form the final products.

Tunable and Versatile: A Breakthrough Technology

The strategic advantage of HyaPak’s technology lies in its tunability. They can adjust fiber-to-binder ratios and processing parameters to define the final material’s properties. This tunability allows them to create a wide range of products, from seedling pots that break down in months to more durable packaging materials.

For instance, one of their most relevant case studies is a pilot project with the Kenya Defence Forces (KDF). Together, they tackled a secondary pollution crisis caused by billions of single-use plastic seedling bags used in the “Jaza Miti Initiative.” HyaPak provided biodegradable seedling pots and bags to replace the conventional plastic ones. This solution reduces pollution, increases efficiency in the seedling process, and eliminates the transplant shock that previously occurred.

Beyond the KDF example, HyaPak’s technology has the potential to create a significant impact across multiple industries.

The Road Ahead

Aware of its versatility, HyaPak is committed to creating environmental, technical, and social impact worldwide, beyond Africa. Currently, they are discussing collaborations in Mexico, Nigeria, India, and El Salvador to replicate their model. Moreover, the company continues seeking partnerships with governments, scale-up partners, R&D organizations, distributors, FMCG, and food packaging companies.

HyaPak is a strong example of how a problem can become an opportunity. Beyond addressing one issue, it now tackles three: water hyacinth, plastic pollution, and social challenges.
