You can’t venture more than a few hundred yards without encountering a sustainable concept in Amsterdam and its surrounding areas. Windmills and wind turbines are everywhere, bicycles outnumber people and, as a South African journalist joked today, the sheep are the lawn mowers here.
Sustainable products have made their way into the greenhouse, as well. The one that struck me most Wednesday was a fibrous material called Rockwool that Tomato World uses as its growing media. A company called Grotop manufactures the Rockwool, which Tomato World uses for all tomatoes on site.
Once Rockwool has run its course, it is shredded and stored for six weeks before being converted into brick. The plastic residue is also recycled for synthetics companies, making the media 100 percent recylable.
