Turning waste into hand sanitiser is the next project for a research winery based in Marlborough.

The Ministry of Business and Innovation (MBIE) has awarded $84,700 in funding to Bragato Research Institute (BRI) for a pilot study exploring turning grape marc into hand sanitiser.

Grape marc is the stems and seeds leftover after pressing – which in Marlborough can total as much as 46,000 tonnes of waste per year.

The study would look to turn winery waste into ethanol. Any sanitiser made in the initial eight-month study would be bottled and donated to Marlborough health workers and first responders.

Bragato Research Institute chief executive MJ Loza said the industry was continuously looking at alternative uses for grape marc, and Covid-19 presented BRI with “an opportunity to learn more about its properties while exploring a potential business case for a new product”.

“Using winery waste to produce ethanol for hand sanitiser is untested in the New Zealand context with our varietals. We haven’t had the capability to conduct a study like this in New Zealand until now,” Loza said.

“Managing grape marc has probably been viewed as a disposal issue. However, the marc itself is increasingly being studied for other properties.

“Transforming the wine industry’s waste into a value stream is a research priority. Every time we study grape marc, we learn a little more about its potential for a new commercial product.”

In the long term, the project would explore the business opportunity for the industry to turn waste into sanitiser, which would include “more information on costs, the infrastructure needed and technical findings specific to grape marc produced in New Zealand”.

“We know that grape marc is rich in valuable compounds. The challenges lie in finding a new economy for grape marc without creating a bigger environmental footprint, as well as finding a financially viable market for a new product,” Loza said.

Funding for the project was secured through MBIE’s Covid-19 Innovation Acceleration Fund, which was created to support research and projects in covid responses, and provide support to develop and deploy products, processes and services.

The project would be led by winery research manager Dr Tanya Rutan and research programme manager Dr Matias Kinzurik.

Bragato officially opened their research winery in February, based at the Blenheim campus of Nelson Marlborough Institute of Technology.

The new facility will trial winemaking equipment, technologies and processes as well as sustainable winery operations.

It will also provide commercial research winemaking services to suppliers and the industry.

Distilleries pause alcohol production to make hand sanitizer

​A US distillery owner who grew increasingly angry as he saw the skyrocketing price of hand sanitiser has decided to do something about it: He’s temporarily converting his operation into a production line for the suddenly hard-to-find, gooey, alcohol-based disinfectant.

Eight Oaks Farm Distillery filled its first 20 bottles this week, a batch destined for charitable groups that need hand sanitiser but haven’t been able to get it due to the coronavirus pandemic. The family-owned distillery plans to dramatically boost production this week and distribute the bottles to charities as well as offer them at farmers’ markets where it sells its spirits and through its website.

The price: whatever people decide to donate.

“We are in a national emergency,” said brewery founder Chad Butters. “What’s the right thing to do? The right thing to do is support this community by providing something that is in desperate need. We’ll flood the valley with hand sanitiser and drive that price right down.”

Other distilleries are also putting their spirits to work to help fill the shortage of hand sanitisers. Green Mountain Distillers in Morrisville, Vermont, is giving away a hand sanitising solution and Durham Distillery in Durham, North Carolina, is donating one to hospitality colleagues, using high-proof alcohol and other ingredients. Patrons must bring their own containers.

“We wanted to do something that would be as positive as possible,” said Harold Faircloth, an owner of Green Mountain Distillers.

Smugglers’ Notch Distillery, also in Vermont, plans to launch a hand sanitiser later this week at its Waterbury and Jeffersonville sites. A portion of the proceeds will be donated to Vermont’s efforts to respond to the virus outbreak.

“I know I have a unique opportunity to help out a little bit and keep my staff employed,” said co-owner Jeremy Elliott, who said 40 per cent of his business comes from bars and restaurants, which are closing in some other parts of the country.

The Distilled Spirits Council of the United States, a trade group, has been in touch with federal regulatory agencies as well as the Trump administration’s coronavirus task force to clear red tape and “make sure we can be quick and nimble and fill a need in the marketplace”, said chief executive Chris Swonger. “We all want to do our part.”

Swonger said government agencies have been very receptive.

At Eight Oaks Farm Distillery, about 115 kilometres north of Philadelphia, workers experimented with high-proof alcohol, aloe and glycerine to get just the right consistency. The recipe is based on one published by the World Health Organization.

As word got out about what Eight Oaks was up to, the distillery began hearing from people and groups in need, including a pediatric cancer organisation and a woman whose 12-year-old son has heart disease and was desperate for hand sanitiser to help keep him safe.

“I cannot find it anywhere and this virus is especially dangerous to him,” she wrote to the distillery.

Stories like that are why Butters was so disgusted with price gougers who were selling sanitiser online for more than US$300 an ounce – and why he decided to shift his company’s focus.

“We’re trying to make sure we continue to provide a paycheck for our employees and support our community however way we can do that,” he said.

For most people, the new virus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia, and death. The vast majority of people recover.

Beyond the humanitarian impulses of individual distillers, the liquor industry also has a vested interest in seeing the virus threat dissipate quickly, given its economic reliance on bars, restaurants and other hospitality and entertainment venues that have been shuttered by the outbreak.

Brad Plummer, spokesman for the American Distilling Institute and editor of Distiller Magazine, said he’s been seeing a lot of talk among distillers interested in converting part of their operations to hand sanitiser.

“The hospitality industry is going to be decimated by this and they are our primary clients. We’re looking for ways to help in the response to this, but also to find other ways to look for revenue streams,” he said.
