Mechanochemical Depolymerization of PET: Kinetic Studies on Alkaline Hydrolysis of Commercial Feedstocks

open access: yesChemSusChem, Volume 19, Issue 3, February 2026.
Complete depolymerization of commercial PET feedstocks in the presence of NaOH is achieved within 20 min under ambient conditions, without any specific sample pretreatment. Depolymerization is accelerated in samples with higher amorphous content due to more efficient interface formation.

Thermochemically Treated Sewage Sludge Ash From Pilot‐Scale Production as P‐Fertilizer for Spring Wheat and Maize in Different Soil Conditions

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 1, Page 81-93, February 2026.
ABSTRACT Background P‐fertilizers made from sewage sludge ash (SSA) may be suitable substitutes for rock phosphate (RP)‐based fertilizers and contribute to sustainable use of waste. In this context, the thermochemical AshDec treatment of SSA (TC‐SSA) has been continuously improved and has emerged as a possible method to produce plant‐available and low ...
