Workshop: ‘400 Years of Poison for Pleasure’

In collaboration with the Centre for Student Acquisition and Study Preparation – BTU College, Dr.-Ing. Ramona Riedel, STEM Ambassador at BTU Cottbus-Senftenberg, is helping to organise the 37th Cottbus Environment Week.

The environmental AI workshop she is leading highlights, amongst other things, that a single carelessly discarded cigarette butt can contaminate up to 60 litres of water, and that it takes up to 400 years for the filter material to decompose. The damage that cigarette butts can cause in gardens is also explained.

The workshop will feature the robot dog developed by the BTU’s College, which specifically tracks down cigarette butts and simply sucks them up before they pollute and harm the environment.

The workshop is part of the lecture series at the Brandenburg State Office for Mining, Geology and Raw Materials (LBGR).
