Bridging Economy and Ecology: a Circular Economy Approach to Sustainable Supply Chain Management

The linkage between economic and environmental issues in an inter-organizational context receives significant attention from scholars and industrial practice. Emerging concepts like Green Supply Chain Management (Green SCM), extending supply chain management with ecological aspects like resource optimization and recycling, might be the first step towards an ecologically responsible economy. But...

Growing Potatoes with Slow-release Nitrogen Fertilizer

Nitrogen management practices have an effect on crop yields but they can also have a negative impact on the environment. Practices such as banding fertilizer and/or split-applying total nitrogen needs per acre offer a more efficient use of nitrogen by significantly reducing nitrate leaching potential. Heavy rains occurring when plants are small and nitrogen demands are low can also increase nit...

Concept of sustainable waste management in the city of Zagreb: Towards the implementation of circular economy approach.

Improvement of the current waste management is one of the main challenges for most municipalities in Croatia, mainly due to legal obligations set in different European Union (EU) directives regarding waste management, such as reduction of waste generation and landfilling, or increase of separately collected waste and recycling rates. This paper highlights the current waste management in the cit...

Characterization and Utilization of Zeolite for NPK Slow Release Fertilizer (RESEARCH NOTE)

Based on various characteristics of zeolite, its utilization in the manufacture of fertilizers with slow-release properties is possible. The objectives of this study are to characterize and utilized nitrogen, phosphorus and potassium (NPK) slow release fertilizer by using natural zeolite in Indonesia. In this research, zeolite was utilized as a mixture of Slow Release Fertilizer (SRF). Effect o...
