We are witnesses of excessive depletion of natural resources, climate change and a loss of biodiversity. Water, air, soil, light and noise pollution is increasing. At the end the quality of life is worsening as well. Interdisciplinary approach is needed. Economy and chemistry are two different scientific areas, which facing environmental challenges develop divergently. The results are that we have green economy and green chemistry; we deal with complex problems sharing our knowledge and supporting each other. Green chemistry is a new paradigm that provides solutions to contemporary environmental, ecological and sustainable challenges. The aim of the paper is to present approaches of green economy and green chemistry, collaborations between them and integrative effort in solving environmental challenges toward sustainability. The goal is to present examples of green business based on green chemistry. Methodology encompasses case studies of companies with green business. This paper contributes to existing research in three ways: it spreads knowledge and good business experiences, it shows long term benefits and it raises awareness of a paradigm shift towards ecology and sustainability.

This paper opens the following question: Is urban gardening a fashion trend, utopia or our future? The aim is to examine the literature and practice to find the answers to the above question respecting the integrative approach. The goal is to compare those three aspects of urban gardening searching for the dominant one. Methodology is based on The World Café Method with participants who are experts from the fields of biology, chemistry and geography. Research results show that the future aspect of urban gardening has a primary and dominant role, although the aspects of fashion and utopia deliver interesting impulses provided by interdisciplinary approach. The contribution of the paper is multidimensional. On the theoretical level, it provides an overview of urban agriculture and gardening. On the empirical level, it reflects complexity of urban gardening and its importance for the future. On both levels, this paper raises the awareness of sustainability
