Model based study of autothermal thermophilic aerobic digestion (ATAD) processes : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology in Engineering and Automation of Massey University [PDF]

, 2000
An Autothermal Thermophilic Aerobic Digestion process, or ATAD process, is a relatively new sewage sludge treatment process. The ATAD process has been developed for the disinfection and stabilisation of sewage sludge, which is a by-product of wastewater ...

Trace elements, pH and organic matter evolution in contaminated soils under assisted natural remediation: a four year field study [PDF]

, 2008
A 4-year study was undertaken on the effect of three amendments (biosolid compost (BC), sugar beet lime (SL), and combination of leonardite plus sugar beet lime (LESL)) on reclamation of a moderately trace element-contaminated soil under field conditions.

Proximate Analysis and Calorific Value of Pellets in Biosolid Combined with Wood Waste Biomass

, 2018
In this study, biosolid and wood waste biomass were used as fuel by turning them into fuel pellets. The purpose of making fuel pellets with various compositions was to compare the type of biosolid pellets and wood waste in terms of proximate testing. The

Azole antifungal contaminants disrupt mycorrhizal function and risk agricultural sustainability

PLANTS, PEOPLE, PLANET, EarlyView.
Global food production is increasingly threatened by soil degradation, climate change and the rising costs of synthetic fertilisers. Circular agriculture, which promotes resource reuse, is a promising solution, but using treated wastewater and biosolids in farming introduces risks from emerging contaminants like pharmaceutical residues.

An integrated social and natural sciences case study for the reuse of organic wastes as soil amendments

PLANTS, PEOPLE, PLANET, EarlyView.
Reusing organic waste materials, such as animal manure, as soil amendments reduces water and fertiliser demand, contributing to achieving the Sustainable Development Goals. However, organic wastes may contain contaminants of emerging concern (CECs), posing potential ecosystem and human health risks. Despite the importance of this issue, there is a lack
