The use of Biochar made from Biomass and Biosolid as a Substrate for Green Infrastructure

The use of Biochar made from Biomass and Biosolid as a Substrate for Green Infrastructure

Paper in proceedings outside WoS and Scopus

In the European Union, current waste and wastewater management is energy demanding and produces many residues or products that can only partially be used/recycled. This paper evaluates the use of biochar made from biomass and biosolids as a substrate for green infrastructure, city parks, green parking lots, and especially green roofs and walls, which are nowadays replacing the ordinary roofing while considered an eco-friendlier solution in urban planning. Because of the existence of different kinds of biochar (made from different feedstocks e.g. sludges, biomass, municipal solid waste, wood, plant residues, etc.), different chemical and physical properties may occur while application; e.g. retention of nutrients, absorption of pollutants and harmful gases, carbon sequestration or improvement of pH of amended soil. Results of the review consider the usage of biochar as a substrate for green infrastructure in pursuance of its characteristics, limiting pollutants concentration, and potential benefits and risks for the environment, water sources and occurring climate change. Since biochar has a positive influence on plant growth and rainwater capturing, its use as a substrate is the main objective of this research paper. The review is based on the analysis of different existing research and case studies related to biochar management, from which the impact of biochar on substrate characteristics, water retention and quality of runoff from green roofs will be elucidated.
