A group of Marlborough investors and scientists have found the fruit of the vine can be good for business and your health in more ways than one.
stuff.co.nz reports that the team formed New Zealand Extracts two years ago to investigate turning what had been viewed as grape seed waste into a concentrated antioxidant product.
Typically fresh fruit and vegetables such as brussels sprouts and broccoli host a lot of antioxidants, important in fighting free radicals in the human body which can damage cells and lead to cancer. Research director Dr Glenn Vile said NZ Extracts had devised a unique way of producing antioxidant extracts from the seeds left over from the winemaking process. They could be then onsold to other companies to use in cosmetic, food and capsule products.
The extracts had been sold offshore, but as a start-up company NZ Extracts did not want to divulge revenues over the first 12 months, Vile said. A lot of research had been done into potential applications and to how to give the product a long shelf life.
"Grape seed extract is an existing product out in the (overseas) market and so we identified some interesting features from New Zealand grape seed," Vile said.
Grape seeds had traditionally been a difficult and costly waste product to dispose of, having to be transported to landfills or processed into animal feed.
"There‘‘s about 20,000 to 30,000 tonnes of Marlborough grape waste so there‘‘s plenty of raw material," he added.
NZ Extracts had developed an environmentally friendly water extraction method to separate high quality extract from the seeds. The extract product â?” marketed under the brand name Oxi-fend Vinanza â?” had been used in the recently launched Hubbard‘‘s Simply Bran cereal. In Wellington a skincare product company called Antipodes was using the grape extract in a cosmetics product.
Firms from the west coast of the United States and from France and Italy had developed health extracts from grape seeds, but they used high volume chemically based extraction.

Waste management poses challenges, but could unlock major environmental and economic gains
Every day, the city of Rio de Janeiro, one of the largest metropolises in the Southern Hemisphere, generates 17,000 tonnes of waste, ranging from large industrial debris to candy wrappers bought innocently at newspaper stands. While this waste presents a serious and urgent environmental challenge, it also fuels an increasingly significant portion of the economy, with benefits extending beyond financial gains. - When we look at developed European countries, many are already recycling between 40% and 50%, with some reaching 60%. From an economic standpoint, both recyclable materials and organic waste hold tremendous value - stated Adalberto Maluf, National Secretary for Environment and Environmental Quality at the Ministry of the Environment (MMA), during the Methane Forum: Climate Emergency Brake, at the Rio Nature and Climate Week. Citing a 2025 report, Maluf mentioned that Brazil literally throws away R$27 billion annually, while municipalities spend significantly more - R$45 billion - managing all this waste, often overlooking the environmental impact or economic potential buried in landfills and dumps. - We spend R$45 billion to collect and dispose of waste in landfills, yet we manage to recycle less than a third of the potential. I believe it will be necessary to review contracts, create performance-based remuneration mechanisms, and pay for both effectively sorted materials and those diverted from landfills - he added. According to the IBGE, 60.5% of Brazilian municipalities adopt some form of selective waste collection, and several initiatives serve as examples of how to manage city waste. In his panel presentation, Bernardo Ornelas, Project Coordinator at the Rio de Janeiro Municipal Urban Cleaning Company (Comlurb), highlighted Ecoparque do Caju, a national benchmark in waste management and recycling. There, received materials are sorted and can be used for biogas production, organic compounds for urban gardens, or human consumption, in the case of still...
