What specific requirements are likely to be placed on a waste manager/processor in regard to the traceability of material they handle?
Unfortunately, I have no experience in working directly with a waste manager/processor. According to my experience, in my own country, the only traceability requirements that I am aware of are: to ensure a chain of type of waste, according to a regulated definition, amount generated, transported, and whom it is processed by. Some countries use a paper trail, others use digital documents.
What processes are waste managers likely to be required to install/undergo in order to be compliant with the ISO?
ISO 14001:2015 has no extra requirements beyond what is already prescribed in regulation or legislation. If your organization already complies with regulation and legislation, the main requirement from ISO 14001:2015 is to: define improvement priorities, translate those priorities into objectives, and design action plans to meet those objectives.
