The performance of vegetable waste composting was assessed using passive aerated static bioreactors at both laboratory and pilot scales. The new formulation tested at the lab scale showed improved compost quality compared to our previous study (Murshid et al., in Int J Recycl Org Waste Agric 13(3):1–12, 2024), prompting a move to pilot-scale experiments. Pilot-scale trials were conducted with Reactor A (featuring four perforated pipes) and Reactor B (equipped with a single perforated pipe). Reactor A exhibited marginally greater efficiency than Reactor B, attributable to enhanced aeration from the additional pipes, resulting in reduced final compost moisture content and increased phosphorus and potassium levels. Each reactor at the pilot scale produced approximately 200 L of leachate, which, based on its quality, has potential for use as a growth medium for plants.
