The UK has a producer responsibility regime in force for the recycling of waste packaging. This means that all businesses which make or use packaging – excluding certain smaller companies – have a legal obligation to ensure that a proportion of that they place on the market is recovered and recycled.
The regime first came into force in 1997 and was updated in 2007 with the introduction of the Producer Responsibility (Packaging Waste) Regulations 2007. There have been a number of amendments to the regulations since 2007.
The supermarket selling a product has an obligation under the Packaging Waste Regulations
Under the regulations, packaging producers can meet their recycling obligations by buying recycling evidence, known as Packaging Waste Recovery Notes (PRNs), or Packaging Waste Export Recovery Notes (P(E)RNs), from accredited reprocessors or exporters. The system is therefore known to many in the industry as the PRN system.
The obligation applies to all those involved in the packaging supply chain – ranging from raw material manufacturers to retailers – which have an annual turnover above £2 million, and which handle more than 50 tonnes of packaging a year. Organisations can also be obligated if they are part of a group that collectively meets the thresholds. Those obligated companies with a turnover of below £5 million can choose to use a simpler allocation method when completing their obligation calculations. Many obligated companies sign up with Producer Compliance Schemes (PCS), who buy evidence on their behalf and take on their legal compliance.
The number of PRNs that companies have to buy is determined by targets which are set by the UK government, known more commonly as ‘business targets’. So far, business targets have been set for all materials up until 2020 (see targets page). The targets cover paper and card, glass (of which a certain proportion must be sent to remelt), aluminium, steel, plastic and wood and there is also an overall recycling and recovery target, for which a certain percentage must be met through recycling.
The PRN system is designed to enable the UK to meet its targets under Directive 94/62/EC on packaging and packaging waste. The Directive required that the UK recovered at least 60% of all packaging waste by December 31 2008 as well as meeting a number of other targets, which the UK comfortably achieved.
However, these targets are expected to rise. Higher packaging recycling targets were finalised in circular economy proposals agreed just before Christmas 2017 by European Member States under the auspices of the Estonian presidency of the EU. These will cover a period to 2030 and are likely to be formally ratified in early 2018.
Unlike many other European countries, the PRN system is a market-based supply and demand mechanism, designed to reduce costs for obligated companies while still ensuring compliance with the European Directive. The system effectively subsidises packaging recycling and means that if the price of recyclables drops, the PRN generally increases in value, thereby providing some protection for the market.
Those who handle packaging and or packaging materials can calculate their obligation based on the amount of packaging they place on the UK market in the previous calendar year. Producers’ obligations are split between different roles within the supply chain, each with a different percentage of responsibility: raw material manufacturer 6%; converter 9%; packer/filler 37%; seller 48%. Importers have a “rolled up” obligation for packaging imported into the UK.
Raw material manufacturer
The raw material manufacturer makes raw materials for packaging manufacture (such as a steel mill). A packaging converter converts the raw material into packaging, (such as making sheets for cans). A packer filler puts products into the packaging or packaging around the product (such as a company putting baked beans in a can) and the seller supplies an end user, (such as selling the cans of baked beans to the consumer).
Companies must account for all activities which are carried out on the packaging they handle. The calculation is therefore: packaging placed on the market in the previous year multiplied by responsibility percentage multiplied by national business target. The calculation then provides each obligated business with a fixed tonnage obligation at the start of each year that they must fulfil by proving that they have funded the equivalent tonnage of packaging recycling, thus providing the demand within the market mechanism.
For each tonne of packaging material recycled or recovered, the final reprocessor or exporter is entitled to produce a PRN or PERN (Packaging Export Recovery Note) certificate, provided they are audited and accredited by the enforcement agencies.
Materials which are exported for recovery are treated equivalently to UK processing as long as the end destination can be shown to the enforcement authority to have broadly equivalent standards. The majority of producers either join a Packaging Compliance Scheme, who will take on their legal obligation and obtain the PRNs on the producer’s behalf, or alternatively the Producer can register direct and can then obtain these certificates themselves, as evidence of meeting their legal obligations.
The Advisory Committee on Packaging (ACP) have produced the PRN System Guide which provides a detailed explanation of the UK PRN system.
To monitor fulfilment of the national targets, producers, PCSs and accredited reprocessors and exporters have legal obligations to report certain data to the relevant enforcement agency. All information is maintained on the National Packaging Waste Database (NPWD) and reported to the European Commission.
