The article presents the directions of foundry waste management, mainly used for spent foundry sands (SFS) and dust after the reclamation of this waste. An important aspect of environmental protection in foundry production is the reduction of the amount of generated waste as a result of SFS regeneration. The advantage is the reuse of waste, which reduces the costs of raw materials purchase and environmental fees for landfilling. Non -recycled spent foundry sands can be used in other industries. SFS is most often used in road and construction industries as well as inert material in closed mines (Smoluchowska and Zgut 2005; Bany-Kowalska 2006). An interesting direction of using SFS is its application in gardening and agriculture. The article presents the advantages and disadvantages of such use. It was found that spent foundry sands can be useful for the production of soil mixtures for many agricultural and horticultural applications. Due to the possibility of environmental pollution with heavy metals and organic compounds, such an application is recommended for the so-called green sands, i.e. SFS with mineral binders. In addition, an innovative solution for the energy use of dusts after spent foundry sands reclamation with organic binders has been discussed and proposed by some researchers. It was shown that dust from reclaimed SFS with organic binders can be used as an alternative fuel and raw material in cement kilns, due to the high percentage of organic substances which determine their calorific value and silica.
The two chosen estates, Garnizon and Wiszace Ogrody have evolved during the last decade or so in Gdańsk. Both developed with the idea of balanced functionality and New Urbanism despite very diff erent locations. The aim was to combine apartment buildings with shops, other services, hotels, offi ce buildings and cultural venues. Numerous interesting and inviting public spaces were also high on the agenda. It was intended to create an interesting, multifunctional space, to maximise the use of the space throughout the day, also making it eco friendly by minimising the use of cars. That`s how an interesting, beautifull space impacts the energy. The centrally located Garnizon has been quite successful, whereas the more peripherally placed Wiszące Ogrody has not quite succeeded due to fi nancial restrictions and is mainly a housing estate at the moment. The hope is that it will grow into a similar entity with new development and helped by the new rail link.
