Adelaide is the one of the biggest environmental sustainable cities in Australia and local officials are working hard at maintaining its status as one of the cleanest areas in the world. Its wide parkland and green areas add a lot of charm and fresh oxygen to this already picturesque city. One of the most important activity officials have implemented in the area is represented by Adelaide’s recycling system, which recycles approximately 85% of all wastes.
