Abstract
The paper studies the effect of various
additives (activated carbon, wood ash, and biological activator) on the process
of aerobic composting of organic waste. The key process parameters were
assessed: temperature, humidity, C/N ratio, electrical conductivity, and
germination coefficient. The results showed that the use of additives
accelerates the thermophilic phase, improves aeration, reduces nutrient losses,
and increases the quality of the finished compost. The biological activator
ensured the most significant decrease in C/N (up to 16), an increase in the
germination coefficient up to 92%, and rapid achievement of compost maturity.
Activated carbon improved aeration and reduced phytotoxicity, and wood ash
increased the mineral content, but led to an increase in electrical
conductivity, which requires control. Comparison with data from other studies
confirmed the obtained results and showed the promise of using these additives
for accelerated production of mature and environmentally friendly compost.
