Please wait... @marthastewart48 : The company that has so carefully processed my trees by tub grinding is #materialprocessors It costs a significant amount to "rent" the grinder and the operator and depending on the job , will take a day , a week, a month to complete the grinding process But the resulting material is really useful in any landscape And botanical gardens, parks as well as large private farms and properties use this kind of machinery Good luck!!!
