Efforts to address plastics used in agriculture taking root featured in Globe & Mail’s Next-Generation Farming Report

The Globe and Mail “Next Generation Farming Report” highlights Cleanfarms’ goal to keep agricultural plastics out of landfill and manage on-farm agricultural waste materials in the most sustainable way possible. Cleanfarms has been steadily expanding its range of programs and is currently operating pilot projects to develop efficient ways to deal with bale wrap, in particular.

Prior to having plastics available, tasks like gathering hay were cumbersome. “It took the team six weeks to complete what can now be done by one person in three days,” Mr. Friesen recalls. “Plastics – combined with technology – had a phenomenal impact on the agriculture industry, resulting in much more efficient ways of growing and delivering food.”

Designing a Robotic Berry Picker

Video: Designing a Robotic Berry Picker


Since blackberries must be harvested by hand, the process is time-consuming and labor-intensive. To support a growing blackberry industry in Arkansas, food science associate professor Renee Threlfall is collaborating with mechanical engineering assistant professor Anthony Gunderman to develop a mechanical harvesting system. Most recently, the team designed a device to measure the force needed to pick a blackberry without damaging it. The data from this device will help inform the next stage of development and move the team closer to the goal of a fully autonomous robotic berry picker. The device was developed by Gunderman, with Yue Chen, a former U of A professor now at Georgia Tech, and Jeremy Collins, then a U of A undergraduate engineering student. To determine the force needed to pick blackberries without damage, the engineers worked with Threlfall and Andrea Myers, then a graduate student.
