Recovering dairy manure fibre for use as a higher value plant growing media offers an economically attractive manure management alternative. The objective of this study was to develop a two-step leaching-bed system to process raw fibrous dairy solids and produce a fibre product with improved quality suitable for plant growth. Methodology involved investigating the effects of leaching temperature and flow rate at a 100-liter reactor scale, while optimizing the leaching process to reduce water usage and enhance efficiency. Results indicated that optimal operating conditions included a leaching temperature of 50 °C with a leaching rate of 4 h−1 per dry solids and a washing regimen using a 50/50 ratio of recycled and fresh water. Under these conditions, indicator coliform bacteria were reduced by 1.6 log units and the physical properties of the product were modified to align closely with those of peat moss. Subsequent growth trials affirmed the effectiveness of the developed product as a viable plant-growing medium.
