Wineries turning pomace into power

subscribe

Like others in the wine industry, Vincor Canada used to send most of its leftover grape skin, pulp and seed to landfills - costly for the environment and the company's bottom line.

But in September, Canada's largest producer and marketer of wine and related products announced a deal with Vandermeer Greenhouses of Niagara-on-the-Lake, Ont., to create electricity using those wine leftovers, known as pomace.

Bruce Walker, executive vice-president of Vincor, says the project is the "most visible" example of the company's interest in sustainable wine-making - a trend emerging throughout Canada's wine industry. "The urgency is yesterday and that is how we are approaching this," he says.

This fall, Vincor shipped about 3,500 tonnes of pomace (most of the processing leftovers from three of its Niagara-area wineries) to Vandermeer's new $3-million anaerobic digester, which breaks down organic matter and captures methane gas for use as electricity in the greenhouse operations. Any surplus is sold to Ontario Hydro's grid to heat and light homes in the Niagara area.

Randy Van Berkel, general manager of Vandermeer, says close proximity to a big supplier of organic material helped the company invest in the digester, with financial assistance from the Ontario government, "at a drastically reduced cost."

Mr. Walker estimates Vincor saved $50,000 by not trucking the pomace to landfills. Vincor now is looking for a partner to invest in an anaerobic digester in British Columbia to process pomace from its Okanagan Valley wineries. Green initiatives also cut costs, he says, citing a retrofit of one Okanagan winery to recycle water at a savings of $75,000.

Mr. Walker, also chairman of the Wine Council of Ontario's sustainable wine-making committee, says the industry's move to more eco-friendly practices creates a "triple bottom-line" impact: a demonstration of social responsibility, cost savings and reduced carbon footprint. This year, 24 wineries (40 per cent of the Ontario industry) signed on to the Wine Council's voluntary guidelines on sustainability, up from 17 a year earlier. The future of green, he says, "is very bright."

Maryland’s renewable energy facilities break pollution rules, say groups calling for enforcement

BALTIMORE - Many facilities that supply Maryland with renewable energy have exceeded pollution limits or otherwise broken environmental rules, violating a state law, according to a complaint sent by environmental groups to state energy and law enforcement officials.

Maryland law says that any company that contributes to a state renewable energy goal — half the state’s energy portfolio must come from renewable sources by 2030 — must “substantially comply” with rules on air and water quality and waste management. The complaint says more than two dozen power generators, including paper mills and trash incinerators, have records of formal or informal enforcement…
