COVID-19 – The US Composting Council would like to thank all of its members and partners for their support during these challenging times. Our hearts go out to all those who have been affected by the global pandemic.

USCC’s mission is to produce the gold standard conference and trade show for the compost and organics recycling industry every year. With that said, we are closely monitoring the situation (including Southern California where COMPOST2021 will take place) and we are constantly reviewing public health guidelines as well as new data so that we can make the best plan moving forward for COMPOST2021. Part of this plan includes a hybrid approach for those who will choose to attend either in-person or virtually.


The US Composting Council advances compost manufacturing, compost utilization,
and organics recycling to benefit our members, society, and the environment.
