Edmonton is one of Canada’s leaders in waste management and recycling. For decades, the city has actively rolled out an effective waste separation system, which is now considered one of the most advanced in North America. Proper waste sorting is a crucial contribution by residents to environmental conservation, sustainable development, and the city’s future. Thanks to a responsible approach to recycling, it is possible to reduce pollution, cut resource consumption, and support the growth of the green economy, according to edmonton.name.
The waste sorting system in Edmonton is based on three main streams:
- Blue bins — for recyclable materials.
- Green bins — for organic waste.
- Black bins — for non-recyclable garbage.
Each stream has its own specifics, rules, and purpose. To make the most of this system, it is essential to understand which types of waste belong in each category and how to properly prepare them for disposal.
Plastics: Types and Disposal Rules in Edmonton
Plastic is one of the most challenging materials to recycle because there are over 100 different types, each with distinct properties, melting points, and recyclability. Edmonton’s recycling system doesn’t accept all types of plastic due to the technical limits of the equipment at recycling facilities. Understanding these limitations helps residents sort plastic correctly and prevents contamination of the recycling streams.
Rigid plastic containers are the primary category of plastic accepted for recycling in Edmonton. This includes bottles from household chemicals like shampoos, detergents, and paints. All these containers can be tossed into the blue bins. Dairy product bottles are also accepted, but they must be empty and rinsed before disposal. Food residue contaminates the entire stream of recyclables at the plant, turning large volumes of otherwise good materials into non-recyclable trash. Edmonton also accepts plastic clamshell containers, commonly used when berries, salads, mushrooms, and eggs are sold. These often confuse people because they feel flimsy and seem unrecyclable. However, the sorting equipment is specifically designed to handle them. Rigid plastic items are also accepted. This means single-use plastic cups, usually clear or white, can go in the blue bins too. However, you need to be careful with plastic bags, as not all of them are recyclable. To figure out if a plastic bag can be recycled, try the “stretchy test.” If it stretches easily and remains elastic, it can go in the blue bin. It is best to stuff all these stretchy bags into one large bag, tie it off, and place it in the blue bin. Bags that fail this test belong in the black garbage bin. Typically, these are made from a different type of plastic that Edmonton’s program doesn’t process. In 2022, the city expanded its recycling program for expanded polystyrene (Styrofoam). Large pieces, such as packaging blocks and coolers, are now accepted at Eco Stations. Plastic cutlery, including plates, forks, and knives, is not accepted in Edmonton’s recycling. These items often get mixed up with others and can damage expensive equipment at the recycling facility. Prepping your plastic for disposal is crucial for successful recycling. All containers must be emptied and rinsed before going into the blue bin. Cold water easily removes leftovers, and the whole process takes just a minute.
Glass: A Simple Material with a Complex Recycling Process
Glass is considered one of the easiest materials to recycle. Edmonton accepts almost all types of glass containers. Unlike plastic, glass is sorted into several categories. This includes wine, beer, and other beverage bottles. Glass jars from ketchup, mustard, jam, and pickles are also accepted. Prepping glass for recycling is slightly different from prepping plastic. Glass containers need to be empty, but they don’t have to be washed out perfectly. It is important to remember that glass is fragile, and mixing it loosely with other materials in the blue bin can cause problems. If it shatters inside the bin, the tiny shards mix with paper and cardboard, rendering them unrecyclable. Therefore, you should put glass items in a separate bag and place it at the bottom of the blue bin, safely tucked under other materials.
The glass recycling process in Edmonton takes place at the Materials Recovery Facility within the Edmonton Waste Management Centre. Here, the glass is smashed into small pieces. After sorting, it is transported to Airdrie, a city located about 200 kilometres southwest of Edmonton. There, it undergoes further processing, is ground down to a sand-like consistency, and sold to manufacturers of fiberglass home insulation. In Edmonton, you can also return certain glass containers to bottle depots and get a refund. These items are processed separately from the blue bin glass. They are often sent to refill centres, where they are sanitized and refilled with new products, or they are sent to specialized recycling facilities.
Organic Waste and the Comprehensive Composting System
Organic waste makes up a massive chunk of all household trash. In 2021, Edmonton rolled out a three-stream waste management system, creating a dedicated stream just for organics. Single-family homes use green bins for this, and the city plans to expand the program to all multi-unit buildings by 2027.
Green bins accept almost all types of food scraps with virtually no restrictions. You can toss in meat, bones, seafood shells, veggies, fruits, bread, and baked goods. Food-soiled cardboard is also good to go for composting. Yard waste is no exception; grass clippings, fallen leaves, and dead flowers all belong in the green bin. One of the more unique rules in Edmonton involves kitty litter and pet waste. Unlike most other North American cities, Edmonton allows you to put kitty litter right in the green bin. It should be disposed of loose or in certified compostable bags. Starting in 2023, the city also allowed the use of regular plastic bags as green bin liners, provided they are removed at the composting facility.
The organic waste composting process in Edmonton kicks off with weekly green bin collection. The materials are hauled to the Edmonton Waste Management Centre, where they go through a debagger to strip away any liners used in the bins. Next, the material gets screened to pull out any contaminants that might have accidentally slipped into the organics stream. The remaining organic material is then processed into compost either on-site in Edmonton or by a regional contractor nearby. Additionally, some organic waste is sent to the High Solids Anaerobic Digestion Facility. Here, materials are mixed with wastewater and wood chips, breaking down over about a month. This process produces both compost and renewable energy in the form of biogas.
Starting each May, the finished, high-quality compost is given away for free to Edmonton residents at the Ambleside and Kennedale Eco Stations. People can take as much as they need throughout the season to use in their gardens and flowerbeds. This creates a closed-loop system where food scraps are transformed into a valuable product that enriches the soil and keeps backyard gardens healthy. This process also saves residents from having to buy expensive fertilizers and soil amendments.
Drop-off Systems and Alternative Disposal Methods
Beyond the primary blue bin system, Edmonton runs a network of Community Recycling Depots. Scattered across the city, these depots give residents 24/7 access to recycling. They accept mixed recyclables, including cardboard, plastic, paper, and metal. People simply drop their items into the clearly labelled bins.
There are roughly 20 recycling depots operating citywide. This setup lets Edmontonians drop off recyclables on their own schedule, without waiting for garbage day. It is especially handy for those doing home renovations or anyone with a massive pile of recycling to clear out. However, these depots don’t accept everything. Items like furniture, electronics, tires, and appliances are prohibited here and must be taken directly to Eco Stations.
To make waste sorting foolproof, Edmonton developed the free WasteWise app. Residents just type in the name of the item they want to ditch, and the app gives precise instructions on exactly which bin it goes in. You can also use it to check your collection schedule.
Looking at the big picture, the waste recycling system in Edmonton isn’t perfect, but it stands out as one of the most comprehensive and effective in Canada. With new programs and expansions, it continues to evolve. By taking waste sorting and collection seriously, residents make a massive contribution to building a more sustainable future.
