Methodology for PCF Calculations of Lubricants, Greases and other Specialties
systems with large value differences between products and is therefore not relevant in this context.
In addition to these rules, this methodology acknowledges that some products within the lubricant manufacturer’s value chain apply to other PCF methodologies, guidelines, or PCRs, as described in Section 2.2.
Thus, this methodology accepts other allocation principles according to Section 2.2. It is important to keep in mind that the allocation principle has a major impact on the PCF value, thus it shall be reported to and from the lubricant manufacturer as per Section 6.
Modeling of waste, wastewater and recycling
This section discusses how waste and wastewater treatment (cf. Section 3.4.1) as well as material recycling (cf. Section 3.4.2) shall be handled. A waste is any substance or object that the holder discards or intends to discard, e.g., per European Waste Framework Directive.
Herein, waste and wastewater are simplified by the term “waste”. 3.4.1 Waste treatment
In the following, this methodology presents how waste and wastewater treatment shall be handled depending on different scenarios: • Scenario 1: waste treatment without energy recovery • Scenario 2: waste treatment with energy recovery within the system boundary • Scenario 3: waste treatment with energy recovery outside the system boundary
Scenario 1: Waste treatment without energy recovery
The simplest scenario is the waste from the lubricant manufacturing process of a lubricant or other speciality product which is incinerated without energy recovery. The GHG emissions of the incineration shall be fully allocated to the lubricant or other speciality, as shown in Figure 5.
