We have a newly launched website/resource that can be used to for farmers/cities/companies to input any source of carbon that can be used for composting. Please make people aware of this site if they have any material (wood chips, shavings, lawn clippings, hay, stocks, etc) that could be donated/sold to producers needing it to compost carcasses.
While small amounts are not discouraged, to efficiently help producers, think of sources by the dump truck/semi load. Additionally, it can be searched by county for producers to know what is available to them and at what cost. That website is https://disastercare.unl.edu It does require people to create a simple account, but that is mainly so people that enter material can remove it when it is gone and to make the data a bit more secure than just simply open to the world.
