MARINE EQUIPMENT SERVICES & SUPPLIERS New Product from Zwanny: The Trash Trawl
Zwanny are the exclusive agents and distributors for SpillTech equipment. SpillTech, the Norwegian company that specialises in systems to collect waste in ports, is expanding its services to tackle waste pollution issues in rivers.
Zwanny has supplied several UK ports with the PortBin, which is the original invention of collecting floating waste like plastic and cans etc. PortBin has 2 models, S (for Short or Shallow applications) and XL (for larger collecting requirements). The units supplied hold up to a 30 litre basket for the waste collected and, as a result of their design (based on customized oil spill technology), do not to have pump problems.
Zwanny has gone to the next stage and can now offer the Trash Trawl a new waste collector system which would be used in a river or canal with the flow to collect the floating trash.
Pollution and littering is having an
impact on water quality in rivers as well as ports. “Many rivers are becoming increasingly polluted, so it is important to collect as much waste as possible and that is the reason why we have developed a new waste collector system.”
The system, dubbed Trash Trawl, is currently being tested by the Norwegian Environmental Agency in the Akers river in Oslo. The system works on the high-speed boom principle that is common in oil spill recovery. It uses a boom system that feeds floating garbage to a meshed net, which is emptied two to four times a week.
An important aspect of the development work has been to ensure that the equipment is easy to handle and yet robust enough to withstand adverse river conditions.
“It is a very simple, effective and robust way to collect waste and it is already producing positive results, gathering a lot of debris in the Akers river each week. Clearly, there is a
need to develop new systems such as PortBin and/or Trash Trawl to help address the increasing pollution problems in our rivers and also catch the garbage before it reaches out to the sea and causes further damage.”
