Turning eggplant residuals into high-performance construction panels may sound unconventional, but Dutch innovator Reduco is proving that circular building solutions can come from the most unexpected places.

According to Greenport West-Holland, these panels are fully circular, moisture resistant and fire safe, offering a promising alternative to conventional construction materials. Founder Wilfried Martens now hopes the market will adopt the product, enabling large-scale production in the coming years.

Martens did not originally come from the construction sector. After working as a dairy farmer, he decided to leave agriculture behind and pursue a new direction. A chance encounter with eggplant nursery Greenbrothers in Zevenbergen sparked an innovative idea: could residual streams from eggplant cultivation be transformed into durable building panels? This question led to the creation of Nova Lignum thirteen years ago. Although that company eventually went bankrupt, the concept itself proved resilient.

Reduco emerged as the successor, operating as the production arm of the cooperative Beyond Wood. The cooperative’s mission is to add value to agricultural residual streams for the construction industry. Initial success came from using willow residuals, and once that process was proven, the earlier eggplant concept was revived as a next step towards fully circular construction materials.

Wilfried Martens explained the reasoning behind this structure, and said, "It is important to create a high-quality building material to compete in construction, because you are dealing with competition from current products. By working together in a chain, you can create value together and strengthen each other. That is why the entire chain is represented in the cooperative Beyond Wood. It is a way to work together towards social goals and find better solutions than each on their own."

The collaboration with Greenbrothers was built on trust and shared innovation. Processing eggplant stems presented technical challenges, particularly the need for intensive manual preparation.

For now, production is paused, but momentum is building. The eggplant initiative is also featured on the Bioboost platform, which connects and promotes biobased innovations within horticulture, reinforcing the role of plant-based residuals in the future of sustainable construction.

The Philippines has taken a decisive step toward strengthening its position in global aquaculture with the launch of its largest crayfish nursery—a flagship development designed to scale production of the high-value Australian Redclaw crayfish.

The project, built through the partnership of Farm Fresh Early Catch Inc., Taiwan’s Da Shin Biotech Ltd., and the Department of Agriculture’s Bureau of Fisheries and Aquatic Resources (DA-BFAR), marks a defining moment for the country’s fast-growing aquaculture sector.

The new nursery will focus on mass-producing Cherax quadricarinatus, a resilient and fast-growing species prized by both domestic and international markets. Government officials say the initiative supports national efforts to strengthen food security while boosting long-term livelihood opportunities in rural areas.

Agriculture Secretary Francisco P. Tiu Laurel Jr., in remarks delivered by Assistant Secretary and spokesman Arnel de Mesa, highlighted the power of collaboration behind the facility. “Built through the partnership of Farm Fresh Early Catch Inc., Da Shin Biotech, and the DA-BFAR, this nursery shows that when government, private innovators, and fisherfolk come together, progress stops being a dream—it becomes our shared reality,” he said.

Tiu Laurel added that crayfish aquaculture “opens new doors for our fisherfolk—bringing in more income, more livelihood, and more food on our tables,” while underscoring the need for responsible production and adherence to BFAR’s ecological protection guidelines. Every pond, he said, must “nurture care, discipline, and respect for the balance of our ecosystems.”

Situated in Candaba - a wetlands area renowned for its freshwater abundance—the 1,280-square-metre facility features 16 tanks capable of producing up to 48,000 fry every two weeks. It also introduces advanced water-recycling systems that help reduce waste and conserve freshwater, addressing one of the most common environmental criticisms of aquaculture operations.

The nursery will supply Farm Fresh’s existing 3-hectare grow-out ponds, which already produce around 30 tonnes of market-ready crayfish each year. It will also support a broad network of partner growers as production expands nationwide.

From 2026, Farm Fresh plans to roll out large-scale grow-out operations covering 1,500 hectares in Luzon and 750 hectares each in the Visayas and Mindanao. When these sites reach full capacity, they are projected to deliver more than 1,200 tonnes of crayfish every six months—volumes that could position the Philippines as a competitive player in the regional and global aquaculture market.

Crayfish provide a nutrient-dense, low-impact protein source that requires minimal feed. The project is expected to generate over 3,000 direct jobs and stimulate additional enterprise in farming communities.

The launch marks the beginning of a world-class crayfish industry designed to place the Philippines firmly on the global aquaculture map.

Hydroponic Systems is helping greenhouse growers tackle the challenge of optimising microclimates without compromising light or productivity.

In warm regions, particularly for heat-sensitive crops like strawberries, tomatoes, and peppers, managing radiation, temperature, and heat stress is critical. Heat-diffusing mesh has become an essential tool in balancing light levels and reducing heat buildup inside greenhouses, proving to be one of the most effective solutions for these challenges.

The mesh works by partially blocking infrared radiation while allowing useful diffuse light to pass through. This reduces internal temperatures, alleviates heat stress, and sustains photosynthetic activity. According to Hydroponic Systems, this approach helps "improve fruit quality, reduce plant stress, and stabilise growing conditions," especially during periods of high radiation.

The mesh achieves this through a combination of light diffusion and thermal reflection. The diffusion process disperses light, preventing hot spots and ensuring even distribution of photosynthetically active radiation (PAR) across the plant canopy. This enables middle and lower leaves to contribute more effectively to photosynthesis. Aluminium particles embedded in the polymer structure reflect infrared radiation, which helps control heat accumulation. The result is a more stable greenhouse environment with fewer temperature spikes.

Hydroponic Systems recommends the Agrifresh aluminium thermodiffuser mesh as a proven solution. This patented fabric creates an effective thermal barrier without compromising light quality. According to the company, it works best in professional greenhouses of around half a hectare or more, where managing temperature and radiation is crucial for maintaining high yield and quality.

In practice, reduced infrared radiation leads to lower heat accumulation and fewer temperature fluctuations, especially during critical growth stages. Increased diffuse light improves PAR distribution, supports stable photosynthesis, and reduces the risk of heat stress. As a result, growers experience "more uniform fruit, fewer deformities, and better colour and firmness."

Strawberries, in particular, show significant benefits, with improved uniformity, firmness, colour, and crop stability. Similar positive trends have been observed in tomatoes, peppers, cucumbers, and other crops.

For optimal performance, proper installation is key. Correct height, tension, and orientation affect the mesh's effectiveness. Hydroponic Systems advises careful integration with ventilation systems for best results.

The Ministry of Agriculture, Food and Rural Affairs (MAFRA) has designated seven provinces Gyeonggi-do, Gangwon-do, Chungcheongnam-do, Gyeongsangbuk-do, Gyeongsangnam-do, Jeollabuk-do, and Jeollanam-do as the first-ever “Green Bio Industry Promotion Zones” in accordance with Article 15 of the Act on the Promotion of the Green Bio Industry.

This milestone marks a significant step in the Republic of Korea’s strategy to strengthen its green bioeconomy and drive sustainable industrial growth.

Introduced for the first time this year, the Green Bio Industry Promotion Zone system is designed to establish a comprehensive, region-led framework for business support. The initiative is built around provincial hubs where green bio companies, universities, research institutes, and essential infrastructure for technology verification and certification are closely integrated. Through this clustered approach, local governments are expected to play a leading role in nurturing innovation, accelerating technology transfer, and supporting market-ready solutions.

The selected zones were evaluated and designated following a rigorous assessment process. Key criteria included industrial growth potential, implementation capacity, policy relevance, and overall feasibility. This ensures that each province is well positioned to contribute effectively to the national green bio strategy while leveraging its own regional strengths and resources.

The green-bio industry itself is regarded as a next-generation growth engine, encompassing six major sectors: microorganisms, natural products, food materials, insects, seeds, and veterinary medical products. With the designation of the Green Bio Industry Development Zones, collaboration networks among provinces are expected to deepen. In parallel, processes for verification, evaluation, certification, and commercialisation of green bio technologies and products are set to accelerate, helping to create a dynamic and competitive innovation ecosystem.

MAFRA plans to support the designated provinces by granting eligibility to participate in government-funded infrastructure development projects, including the Green Bio Venture Campus and advanced biofoundries. In addition, policy incentives will be provided to companies operating within the zones, further encouraging private-sector participation and investment in sustainable bio-based industries.

To ensure accountability and continuous improvement, MAFRA will receive quarterly performance reports from the local governments managing the designated zones. Annual performance evaluations will also be conducted to closely monitor implementation progress. Importantly, the results of these evaluations will be reflected in the formulation of policies for the following year, reinforcing a results-driven and adaptive governance approach.

Through these measures, the ROK aims to position itself at the forefront of green bio innovation, fostering regional development while advancing a resilient, sustainable bioeconomy aligned with global green growth trends.
