Lidar deployed to waste plant operations

28 July 2021

Chalk up another use case for lidar as the technology is being used in a waste plant operation to help with efficiency and to minimize environmental impact.

Quanergy Systems Inc.’s M-series 3D lidar is being used to scan the surface of the waste piles at an incineration plant in China and to create a 3D point cloud image to calculate the volume of the waste. The lidar features an angular resolution of 0.033° and point cloud density of up to 1.3 million points per second.

Quanergy is working with Hunan University and Hunan Qiaokang Bridge Health Intelligent Technology for Puxiang Bioenergy.

Through this accurate data, the waste plant can estimate the density of the waste and apply logic to determine the calorific value. This allows the recycling station to prioritize burning high calorific value dry fuels while giving wet waste more time to dry out.

"Before LiDAR, there was no way to accurately measure the volume and density of the waste, critical data points for accurate calorific value estimation," said Enzo Signore, CMO at Quanergy. “3D LiDAR opens up clear and valuable insights that were previously inaccessible in the 2D world, not only improving operational efficiency, but also making the air cleaner and healthier by reducing emissions.”

Quanergy said its 3D lidar sensors can be installed in any environment, indoor or outdoor and provide performance regardless of ambient lighting conditions.
