In situ phytomanagement with Brassica napus and bio-stabilised municipal solid wastes is a suitable strategy for redevelopment of vacant urban land

•Phytoremediation assisted by bio-stabilised material increases the agro-economic potential of vacant urban soils.•Bio-stabilised material is a useful amendment for sustainable plant production, as it increased leaf area of Brassica napus.•Application of bio-stabilised material increased microbial activity of peri-urban soils.•The lower application rate of bio-stabilised material (50 t ha–1) resulted in high improvements in plant and soil parameters.•It is possible to redevelop peri-urban vacant soils by using energy crops and properly treated urban solid wastes.
