The Green Clean
You want to use manual cleaning as a solution to the trash on your beach. However, the municipality can not get enough volunteers involved to make it work. A solution could be to decide to reduce the frequency of manual cleaning Thereby lowering the workload for the volunteers/workers. Prevention methods can be used to still reduce the amount of waste present and allow the decrease of intensity.
Alternatives are to move the wrack that is present on the beach to the edges of the beach that are less frequently visited. This way the nutrients still stay at the beach, But the part that the tourists visit can be cleaned. In addition, more waste bins could be added, or the waste bins could be emptied more frequently. This way the chance of litter just being dumped on the beach is lower, reducing the cleaning costs.
Smoke-free zones could also be implemented. This way smoking is totally prohibited on the beach or smokers could have a designated area where they can smoke, like a terrace. preventing cigarettes from ending up on the beaches can already result in a lower need to clean manually.
