Fertilizer value of wastes and their corresponding biochars
Md Zahangir Hossain, GCER – University of Newcastle

The surplus manure and biosolids can be managed through biochar production to make them as potential fertilizers. These wastes are rich in plant nutrients, and after synthesizing biochar these biomasses became enriched with remarkable nutrients (particularly N, P and K) and high pH values as well as reduce heavy metals availability.

 

Innovative approach for identification of microplastic in biosolids and soils
Dr Mehran Rashti & Dr Maryam Esfandbod, Griffith University

Microplastics have been notified as a newly emerging contaminant in international scale, so the awareness about this issue is slowly increasing within policy.The proposed methods is innovative for MP quantification developed based on reviewing worldwide available literature where collective techniques were utilised to provide the best possible outcome in obtaining MPs from samples with high organic matter content whereas the current methods is not suitable.

 

The economics of recycled organics in vegetable production
