Scrubbers are not environmental angels

Scrubbers are not environmental angels

Researchers at Chalmers University of Technology in Sweden have discovered that the wash water from exhaust gas cleaning systems (scrubbers) on ships is the main cause of environmental pollution in harbour areas. The environmentally hazardous metals and other toxic substances washed out of the exhaust gas are no longer released into the atmosphere, but into the water, including harbour waters. Emissions Each ship is responsible for various types of pollutant discharges. These include grey water from showers, black water from toilets, antifouling paints and exhaust gases from ship propulsion systems. Standards In order to meet the requirements in the European Sulphur Emission Control Areas (SECA) and the requirements introduced by the International Maritime Organisation (IMO) in 2020, it is necessary to...

Solar panels: recycling - now or later?

These days, anyone who can - and gets a tradesman's appointment - buys a photovoltaic system for their roof, balcony or window frame, and certainly also for their boat, in order to "generate at least some electricity". But even a solar panel has an expiry date! This is not printed on the glass surface, but it happens. Either the panel loses performance, has a technical defect, is damaged by hail or other impact, or becomes obsolete due to new developments. The average lifespan of a solar panel is 20 to 25 years. Very few people think about that at the moment! Even if panels function efficiently for 40 years...
