Montreux Clean Beach Project II
Monthly Activity Report, Nov 23, 2015 - Dec 24, 2015
Montreux Clean Beach Project II (MCBPII) removes
and inventories macro-plastic pollution from the
shoreline of Lake Léman.
The data collected can be used to evaluate current
litter mitigation strategies. MCBPII is designed and
inspired by the citizen science method.
We have reached out to the major universities in the
region (UNIL and EPFL), researchers internationally
and state and local officials.

Date collected
590 pieces of litter were removed in 6.5 hours over the course
of four surveys. Three categories make up 50 % of the items
found:
1. Pieces of foam (polystyrene)
2. Small bits of plastic
3. Bottles and/or broken glass.
The Baye de Clarens has a litter density range of .5 to .08 Pcs/
m², the lowest of the four sites. However, the Baye de Clarens
is the largest survey site at around 500m² and access to ½ of
the beach requires either scaling the lake wall or jumping across
the river.
The restructuring of the river bed upstream has started, the wa-
ter is gray to brown in color and leaves a fine sediment on the
beach and at low points. Like the Veveyse, foamis the most
common item found.
