Webinar recording: MU21006 - Recycling spent mushroom substrate (SMS) for fertiliser in a circular economy
Join the MushroomLink team as we hear about the investigation into spent mushroom substrate and how it could be returned back to grain growers as a value-added fertiliser product.
Speakers include:
Dr Kevin Wilkinson, composting specialist, Frontier Ag & Environment (project leader)
Dr Cassandra Schefe, soil scientist, AgriSci Pty Ltd
Mr David Hawkey, agronomist, AgriSci Pty Ltd
Topics covered in the webinar include:
What a circular economy for SMS might look like
Various forms of value-adding including dewatering, palletisation, nutrient enrichment and emerging waste processing technologies
Some of the technical challenges associated with these processes
Economic and logistical challenges
SMS physicochemical characterisation
Supply chain mapping of wheat production (i.e., straw supplies) in relation to mushroom production
The webinar concluded with an open discussion on the next steps - particularly with respect to SMS-fertiliser product development and possible agronomic field trials, with input from participants.

Please provide your feedback to Kevin, David and Cassandra on where you think future work on SMS recycling should be directed:
a) pelletisation of SMS and demonstration to grain growers
b) economic modelling of SMS biofertiliser products using case studies
c) field trials in grain production and/or vegetable production
d) deep-dive into the economics of value-adding to SMS (cost:benefit)
e) market research into biofertilisers
f) product development research
