What is recovery code R4?
R4 is a recovery code — one of the standard D (disposal) and R (recovery) codes used to record what happens to a waste at its destination. Recovery (R) codes cover operations that put the waste to use — recycling, reclamation, or energy recovery. You give the D or R code when you record a waste receipt in Digital Waste Tracking, and on waste returns to your regulator.
Permitted sites record the D/R code for each load they receive. Receipt of Waste and waste returns both use these codes.
