Project overview
The goal of this project is to identify an optimum composition of recycled plastics materials to develop a first-of-its-kind plastic sheet prototype to be used as concrete formwork in the construction industry. Our team is using post-consumer plastics, high-density polyethylene (HDPE), low-density polyethylene (LDPE) and polypropylene (PP), as well as Type 7 mixed plastics. This product will be made exclusively with recycled plastics content and validated in the field.

The team have analyzed the sample concrete formwork produced by [Re] Waste including chemical, mechanical, environmental, and thermal laboratory testing. The team recently completed the laboratory trials for testing the concrete formwork in a controlled laboratory environment in coordination with Clark Builders and NAIT School of Skilled Trades

Future activities

Plans are now ongoing for testing the samples in a controlled field location in coordination with Clark Builders using a non-structural concrete component in the process.

Project Overview

This project is researching the generation of polymer blends using Heartland Polymers’ polypropylene products and other polymer matrices sourced from external suppliers. This project aims to develop a platform to produce polymer blends using polypropylene from Heartland Polymers mixed with various commercially available post-consumer recycled (PCR) plastics.

Integrating PCR plastics into industrial applications is integral in improving the plastics circular economy, however PCR plastics currently cannot be integrated into existing processes as they have already been polymerized and have variable characteristics compared to virgin plastics (e.g. composition, tensile strength). The project aims to integrate PCR plastics into the value-add chain by mixing them with virgin polypropylene.

Future Activities

The goal of this project is to demonstrate a made-in-Alberta pathway for the development, validation, and commercialization of high-value plastic resins that contain recycled materials.

Timeline

June 2021 to October 2024.

Project overview

The primary goal of this project is to test, validate and demonstrate the blending of post-consumer plastics into asphalts for the Alberta marketplace. Technologies that convert plastic waste to wax products for blending into asphalt have shown favourable results when applied to roadways in warmer climates. This project tests these processes and is monitoring the results in Alberta’s climate conditions. A portfolio of bench-scale waxes produced from postconsumer plastics has been developed and tested with asphalt samples from Alberta, and a wax candidate prototype has been chosen for field trials of the modified asphalt. Four field trial sites were chosen: Heartland Polymers’ Heartland Petrochemical Complex, Alexander First Nations Community, Sturgeon County and Strathcona County. Across the four sites, 3.74 tonnes of post-consumer plastic waste were diverted from the landfill, equivalent to approximately 710,000 plastic bags or about 411,000 plastic water bottles.
 

Future activities

These sites will continue to be monitored to determine the quality and suitability of the modified asphalt for Alberta roadways and climate conditions, with results expected in Fall 2024.

Project overview

The majority of all new Luxury Flooring (LF) products available in the North American market are manufactured using polyvinyl chloride (PVC). The options available to efficiently recycle these materials at the end of their intended lifecycles are not available at the industrial scale. PolyCo is developing Canada’s first LF zero waste facility in Alberta, and aims to incorporate recycled, post-consumer polypropylene into their products to create resilient, circular, and waterproof PVC-free flooring using polypropylene from the Heartland Petrochemical Complex. This project aims to evaluate the impact of recycled polypropylene and other post-consumer plastics based on the key chemical and mechanical performance indicators of PolyCo’s products. The team has conducted thermal and mechanical analysis on all the sample tiles planned for this project.

Future activities

The project closes out soon and the team is wrapping up the key results of the studies which will specify the percentage of post-consumer plastic that can be incorporated into the tile prototypes without affecting the product properties.
