Environmental treatment

The increasing environmental problems caused by plastic waste necessitate innovative waste management and resource utilization methods. This study introduces a single-step approach to synthesizing activated carbon from Polyethylene Terephthalate (PET) plastic waste, utilizing phosphoric (H3PO4) as the activating agent.

Composting is a useful waste treatment for environmental problem, but composting experiment is challenging due to large-scale requirement. Thus, laboratory-scale reactor is of interest for composting experiment. The capability of laboratory-scale reactor to simulate large-scale composting was determined by assessing the quality of produced compost via germination index.
