How agricultural stickers contribute to climate change

(Mitsui Evan / CBC)

About three years ago, Susan Antler was at a composting facility in BC. When a truck full of rotten avocados comes up.

“51 feet, 52 feet [approx. 14 metres] – favorite, [a] Antler, Executive Director of the Canadian Compost Council, said: “The facility did not accept it.”

why? Thousands of rotten avocados are each “contaminated” with small plastics PLU (or price lookup) sticker. It has a standardized number worldwide and identifies the type of produce and whether it is conventional or organic so that the cashier at the supermarket can enter the appropriate price.

Jane Proctor, Vice President of Policy and Problem Management at the Canadian Agricultural Distribution Association, said stickers are voluntary, but most chain supermarkets need it. “This is not a regulatory requirement,” she said. “This is a business requirement.”

Stickers are too small to be sorted during the waste sorting process, but should not be broken down during composting. Antler said the end product was sprinkled as “foreign matter”. It is a compost used to enrich soil in gardens, farmland, parks, etc.

The stickers are not toxic and do not harm compost-probably because they add microplastic to the environment-Antler acknowledged that it was mainly a cosmetic issue. But there is Strict guidelines About the amount of compost, especially high-grade foreign matter. If too much, the compost may not be available on the market.

With the old adage “garbage-in, garbage-out” in mind, composting plants that want to produce and sell high-quality compost must pay attention to the type of raw material.

In a BC facility, Antler offered to remove the stickers from the avocado, but the composting plant manager declined. “The material just went to landfill, as he just drove off the truck.” She is convinced that it would always happen. “Waste is huge.”

It’s not just a waste, it can also accelerate climate change.

Organic matter at compost factory Usually decomposes in the presence of oxygenProduces CO2 and compost that can nourish plants. In landfills, it is broken down into methane without oxygen. Methane is a greenhouse gas that has about 30 times the global warming impact of CO2 for a century. (Some organic plants are Anaerobic digestion, Which also produces methane, but is trapped and burned, so it does not enter the atmosphere. )

However, there are solutions that include other methods of applying PLU to bulk fruits and vegetables, such as:

Procter said that if many customers do not have access to municipal composting, agricultural distributors often do not consider the extra investment worthwhile. She added that the recent introduction of scannable barcodes on PLU stickers that Canadian stores will soon adopt will need to display fine details on labels and maintain durability.

In the meantime, throw the small sticker into a green bottle at home before peeling it off the fruit or vegetable skin or skin.

Reader feedback

Emily Chan’s article on wooden architecture last week We received a lot of feedback from our readers, but some were concerned about the security of the material itself. “There is a reservation for wooden high-rise buildings.” Bob Miller. “These include wood burns. Wood cannot be recycled. Wood is perishable.”

This article from last year It emphasized several fire chiefs’ concerns and included comments from senior Canadian natural resources researchers.

Other readers were concerned about where all the trees came from.

“Are you seriously promoting the removal of the Earth’s trees as an environmentally friendly solution! I think this is a serious flawed logic.” Simon Fountain.

Unfortunately, we have cut down too much forest and cleared it down. ” Joan Thompson. “We can maintain enough space for natural wildlife, clean the air, and replant enough trees to prevent soil erosion. I’m not convinced. We build, build, Build. There are no restrictions. Careful options-pros and cons. “

What on Earth old problem I am here.

Big picture: major players in battery storage

In this space last week we discussed stock market slides for many famous oil and gas companies. This week, Largest provider of lithium-ion battery storage, Will be a key industry in the global transition from fossil fuels. All of these companies supply automakers (and power companies). In addition to Tesla start-ups, there are not only two modern Chinese amperex technology (CATL) and BYD Chinese newcomers, but also more established names like LG Chem in Korea and Panasonic in Japan. The chart below reflects the total storage capacity figures for each company in 2018.

Building a Net Zero House Does Not Sell

Brad McLaughlin says that it should be easy for northern countries like Canada to build homes that are efficient enough to produce more energy than they use.

But N.B. McLaughlin, general manager of MCL Construction Ltd. in Quispamsis, is wondering if reducing greenhouse gases in homes is really a priority in the country.

His Certified Net Zero home has maximized energy efficiency. The house has insulated concrete walls, triple glazed windows, 44 solar panels, and a backup rechargeable battery system.

The surplus electricity will be sent back to the state’s grid in exchange for NB power credits being used on the coldest afternoon in February and on the coldest sun or evening when the sun sets.

However, three-bedroom, two-bath homes stubbornly refuse to sell. Since 2017 we have entered and exited the real estate market.

“It’s not working,” said McLaughlin. “There were many people through it.”

Initially, McLaughlin was offered for $ 695,000. By May 2019, he had reduced it to $ 570,000. This week, he returned a two-storey house to the market for $ 495,000.

McLaughlin points out that the mortgage “stress test” and indifference from bank hired appraisers are obstacles to keeping buyers away from homes with prices higher than these averages. McLaughlin feels that the federal government can do much more to start building these types of homes.

His first proposal is to improve the mortgage stress test that was introduced to cool down the Vancouver and Toronto red housing market. According to McLaughlin, the test is inflexible, and by refusing mortgages for high-priced homes, the buyer can take into account the fact that buyers have no heating or electricity costs, so the net zero-carbon home market Keeps people out of.

He said that appraisers were confused about such sustainable housing.

“Around here, they don’t know how to value it. They just say,” There are similar houses on the street. “” He said. “Well, it might sound the same, but it’s quite different.”

McLaughlin is not just his thoughts. The Canadian Association of Homebuilders and the Canadian Real Estate Association (CREA) are also calling for a system change. St. John’s real estate agent, President of CREA’s National Jason Stephen, said stress tests should be tailored to local markets across the country.

“If this were a system that was introduced to deal with monthly or yearly house price spikes, we just don’t have it. [across] Nationwide, “said Stephen.

During the 2019 election campaign, the Liberal Democratic Party will introduce a $ 5,000 subsidy to net zero home buyers and provide up to $ 40,000 in interest-free financing to homeowners and landlords for energy-saving retrofits I promised. This program is not yet implemented.

Other efficiency programs are already available to builders and buyers in New Brunswick. NB Power offers up to $ 10,000 as an incentive for building energy-efficient homes, and Canada Mortgage offers 15 to 25 percent discount on mortgage insurance costs depending on the efficiency level of the home.
