In 1994 bill no. XXXVI/294/94 of Piekary local government from the 25th February 1994 introduced selective waste collection on the territory of the city. Thus the amount of waste on the waste dump was limited and valuable secondary raw materials were recovered. In 1994 the selective waste collecting was expanded to waste-paper, glass and since 1997, plastics were also gathered. In the city there are at present 186 glass, 185 paper and 70 plastic waste containers
Responsible for the selective waste gathering within the boundaries of the city is Zakład Gospodarki Komunalnej sp. z. o.o. – Waste Management Company Ltd. A new waste dump is to be built soon. The future waste management of the city involves broadening and optimising the selective collecting and selection of waste while encouraging greater involvement of all the citizens in the process.
A significant influence on the aesthetics and conditions of the environment is the broadly defined vegetation, including the municipal green zones. Due to the development of industry and what follows, the great impact on the natural environment there is a constant need of enlargement of the green zones which play such a significant role in an industrial agglomeration In Piekary Śląskie every year there are spring and autumn forestation actions.

The suburbs such as Józefka Colony, Pod Lipami Settlement, Dąbrówka Wielka, Brzeziny Śląskie, Brzozowice-Kamień. S P Settlement and streets Okrzei, Ziętka, Gimnazjalna and Kalwaryjska are already partly connected to the gasification network.
