TLDR
In this paper, the granulation of ammonium chloride (AC) fertilizer has been investigated in a laboratory scale based on the pan granulator at ambient temperature, and significant improvement of granulation efficiency of AC was achieved by using polyaluminium chloride (PAC) as solid binder and urea as granulation additive.About:

Mechanism of cadmium removal from soil by silicate composite biochar and its recycling.
TL;DR: In this paper, a hydraulic silicate gel material was applied to the preparation of biochar, which has good adsorption performance, separation and recovery characteristics, and after three cycles, the recovery rates of SBC and MSBC both exceeded 94.88% and 83.09% respectively.

TL;DR: In this article, a case study was conducted on a compound fertilizer enterprise in the Jiangxi Province of China and the following conclusions were drawn: 97.82% of the emergy input to the system comes from the nonrenewable resources (especially urea and ammonium dihydrogen phosphate); the ecological services and emergy loss derived from pollution discharge, mainly from HCl gas and dust emissions, reach 7.68E+17 sej/yr and 5.76E+ 17 SEJ/yr, respectively, which reduce the environmental sustainability level of the integrated

The effects of viscoelastic properties of the wetting liquid on the kinetics of the disc granulation process
TL;DR: In this article, the impact of rheological parameters of the wetting liquid on granulation kinetics was determined and a model was proposed which makes the process constant dependent on viscoelastic parameters of applied liquids.

TL;DR: Examination of grain yields and N loss pathways in 2 of the most intensive double-cropping systems in China found that current agricultural N practices with 550–600 kg of N per hectare fertilizer annually do not significantly increase crop yields but do lead to about 2 times larger N losses to the environment.

Coagulation by hydrolysing metal salts
Jinming Duan,John Gregory +1 more
TL;DR: In this paper, a detailed understanding of the sweep flocculation mechanism is provided, especially with regard to the role of charge neutralization and hydroxide precipitation. But the results can be reasonably well explained in terms of established ideas, and there are also some uncertainties regarding the action of pre-hydrolysed coagulants.
