Looking at food waste on two different levels

What’s going on in Canada? What about in our communities?

About 40 per cent of food produced in Canada, or about $31 billion worth of food, is wasted, Ralph Martin, a professor from the Ontario Agricultural College’s Department of Plant Agriculture, says.

“And overall on a global scale, about one third of food is wasted,” Martin told a room of observers at AgScape’s annual general meeting at the University of Guelph. “We produce more food than we sell and we sell more food than we consume.”

“One billion people could be fed with the food that’s wasted.”

Martin presented his information during a panel discussion titled Trashing Food Waste. He focused on national and global food waste, and identified six strategies consumers can adopt to reduce it.

“We could spend less money on meat but buy higher quality meat,” he said. “And we could eat more pulses.”

The other five strategies are:

  • feeding people with co-products (using food destined for the garbage to make purees),
  • using food to feed pets or livestock,
  • use it for anaerobic digestion (use the food to break down other biodegradable material),
  • using food for biodiesel, and
  • diverting food from landfills.

Canadian households spend an average of $155/week on food but throw out $31/week, according to Martin. Organic shoppers spend $27/week more, he said.

“That’s like going shopping and buying five grocery bags and leave one in the parking lot,” he said.

And while Martin’s presentation focused mainly on Canada, another presentation revolved around the bins at the curbs of Guelph streets.

“We evaluated residential food waste,” said Mychal-Ann Hayhoe, a Ph.D. candidate at the University of Guelph’s School of Hospitality, Food and Tourism Management. “We did audits of the garbage that went out to the curb.”

On average, Guelph homes produce between 3.5 and 4.5 kg of food waste per week, 53 per cent of which was avoidable, she said.

“When we say avoidable, we mean your loaf of bread that’s gone bad. You left it (in the fridge too long), it gets mold on it and gets thrown out.”

Fruits and vegetables were the highest concentration of wasted food.

“(0.3 to 0.4) kg per day (was) wasted,” said Hayhoe. “40 per cent of this was unavoidable (pits, stems, etc). Lots of people are wasting fruits and vegetables.”

Animal products, including meat and eggs, were wasted less – likely because they’re more expensive items, she said.

“You plan your meals better when (the food) is higher priced.”

When it comes to cereal and grains, all of the food waste was avoidable, according to Hayhoe.

“You buy breads or a bag of rice and 100 per cent of that is edible,” she said. “If you throw it out, that’s 100 per cent avoidable waste.”

According to the Toronto Food Policy Council:

  • Land filled organic matter creates methane gas which is 25 times more damaging to the environment than carbon dioxide,
  • 47 per cent of food waste in Canada happens at home. 53 per cent takes place along the value chain,
  • Canadians wasted $183 kg of solid food per person in 2007, according to Stats Canada, and
  • About 80 per cent of consumer food waste was once perfectly edible.

Evolution of Beef Cattle Farming

Video: Evolution of Beef Cattle Farming

The Clear Conversations podcast took to the road for a special episode recorded in Nashville during CattleCon, bringing listeners straight into the heart of the cattle industry. Host Tracy Sellers welcomed rancher Steve Wooten of Beatty Canyon Ranch in Colorado for a wide-ranging discussion that blended family history and sustainability, particularly as it relates to the future of beef production.

Sustainability emerged as a central theme of the conversation, a word that Wooten acknowledges can mean very different things depending on who you ask. For him, sustainability starts with the soil. Healthy soil produces healthy grass, which supports efficient cattle capable of producing year after year with minimal external inputs. It’s an approach that equally considers vegetation, animal efficiency, and long-term profitability.

That philosophy aligned naturally with Wooten’s involvement in the U.S. Roundtable for Sustainable Beef, where he served as a representative for the Colorado Cattlemen’s Association. The roundtable brings together the entire beef supply chain—from producers to retailers—along with universities, NGOs, and allied industries. Its goal is not regulation, Wooten emphasized, but collaboration, shared learning, and continuous improvement.
