Vita
Daniel Ohl has been a scholarship holder at the INZIN Institute since July 2024 and is researching new indicators and assessments of technologies for the circular economy. He completed his Master’s degree in Applied Chemistry at TH Köln in September 2023 with a focus on green and sustainable chemistry. Before that, he completed his Bachelor’s degree in Business Chemistry at Heinrich Heine University Düsseldorf. Last year, he completed an internship at Prognos AG in the field of sustainability consulting with first projects in the field of circular economy and chemical recycling.

Vita
Alexander Gönner, born on January 18, 1995 in Steinfurt, has been working for Remondis Assets & Services GmbH & Co. KG in the Research & Development Department of Plant Engineering since February 2020. He previously studied physics at the Westfälische Wilhelms-Universität Münster as part of a Bachelor’s and Master’s degree program. During his studies, his research focused on nonlinear phenomena in optics, while he is currently working on the development of novel optical weighing techniques for the recycling industry.
Research topic
Bulk density determination in recycling plants with fiber Bragg grids
In order to achieve the goal of a functioning circular economy, current recycling processes must be optimized so that less waste can be disposed of and more can be recycled. This requires more information about the material currently being processed. One of the main problems here is the bulk density, which can only be measured with insufficient accuracy on conveyor belts due to the uncertainty of the electric belt scales currently in use.
In his research, Mr. Gönner is therefore working on the development of a new type of optical belt scale that promises better properties and greater accuracy than its electrical counterpart. The idea is to use glass fibers in which a Bragg grid has been inscribed. Using the reflective properties of the grid, the bulk density of the conveyed material can be measured precisely and quickly. Above all, the insensitivity to electromagnetic interference, weaker ageing effects and lower costs make an optical belt scale an attractive alternative to the electrical method currently used.
