ABP Alternative Transformation Process

[10/03/17]   Any In-Vessel Composting System (IVC) dealing with ABP category 3 material must ensure the material undergoes a treatment phase in line with UK or European Standards. A high level overview of the requirements of both standards is included below:

Traditionally, IVC operators adopt the UK standard leading to a requirement to size the facility in line with the double handling required through the two barrier process. As well as additional up front CAPEX on the development, OPEX is increased due to increased material movements between the barriers.

A potential alternative to the UK standard is working with the Animal & Plant Health Agency (APHA) to produce an alternative transformation process which still meets the requirements of the ABP regulations. This enables the operator to determine an appropriate standard that can be proven to be effective through laboratory testing. WRM have developed an alternative transformation process that enables the approval of IVC systems with a single barrier. This has been tested with approval from APHA for an operational regulated facility in the UK.

To successfully achieve an ABP alternative transformation process the process must be validated. The first stage involves testing ABP material from the proposed alternative transformation process under lab conditions. If the lab results demonstrate the ABP material is free from certain pathogens the second stage commences with testing at site. The testing at site will be conducted under the supervision of an APHA vet. If successful results are obtained following site testing, then the alternative transformation process will be accepted and the operator can start to process material in line with this newly approved process.

The benefits of adopting this alternative approach include:
