Agglomeration and removal of microplastics from water and food
How to reduce the intake and amount of microplastics in the environment?
- use tap water + use a ceramic or another tap filter
- use metal/glass bottles
- increase the population of algae that help to increase the sorption of microplastics in oceans
- membrane filtration of wastewater
- agglomeration and removal of microplastics in wastewater by Fe- and Al-based salts and other coagulants
- microorganismal degradation and sterilization of drinking water
Humanity-wide avoidance and replacement of plastic
- We should phase out plastic where ever possible. Starting with simpler scenarios first - we don't have to use it for clothing, cutlery, furniture, and a ton of other things.
- We should make a list of scenarios where plastic is seemingly unavoidable and then focus on figuring out viable substitutes. Every substitute brings the potential to form startup-companies around it

The will and the way
- How can we get people to appreciate the urgency of the problem?
- How can the problem actually be solved? What can people invest their effort in?
