By way of experiment, the Port of Rotterdam Authority has started to produce and spread bokashi: a special soil conditioner made from various types of vegetable waste, including prunings, dry leaves and grass. After being ‘harvested’ across the port and industrial area, the organic residual flows are shredded and anaerobically fermented. Some 8 to 12 weeks later, this process yields bokashi, which is spread across various unallocated sites at Maasvlakte 2 to counter drifting sand. This in turn preserves the grass planted at these plotss.
Every year, the Port Authority discards tonnes of organic matter. The current trial, which will last until the end of December, is a first attempt at finding better purposes for these residuals, which would otherwise go to waste. The production and utilisation of bokashi is in line with the Port Authority’s focus on the sustainable development of attractive outdoor areas.
