The Thames21 Plasticblitz!
17th- 25th September 2022
The Problem...
Many people associate plastic waste as being a problem primarily affecting our marine environments. In fact, 80% of this pollution passes through our rivers and streams on its way to the sea.
The issues plastic causes in these freshwater systems are equally as damaging. Plastic waste in our rivers threatens wildlife by entanglement and ingestion. Large pieces of plastic will then break down into smaller pieces which are difficult to remove from the environment.
Many of our rivers are now effectively acting as plastic 'taps', channeling plastic from inland areas to the sea. However, once plastic has entered our rivers, there is no statutory obligation for any organisation or public body to remove it.
Collective action is therefore needed to address this issue and turn off these plastic taps for good.
The Plasticblitz concept
Throughout the Thames basin, numerous grassroots community groups are hard at work raising awareness of plastic pollution, cleaning up their local area and lobbying corporations to reduce their plastic footprint.
The Thames & Tributaries Plasticblitz is an annual event that aims to engage as many community groups and Environment Agency teams as possible with taking part in a simultaneous litter pick and data collection activity around their local river between the 17th and the 25th September 2022.
This event has three key aims:
1) To complete a catchment wide clean up of plastic pollution.
2) To collect data on the most common plastic items found across the Thames basin, and the areas where plastic pollution is most problematic. This data can be used to educate groups, create publicity and lobby business.
3) To join up multiple community groups, amplifying their voices and helping them share ideas.
This year we have support from Rotary in the Thames Valley through their international End Plastic Soup campaign meaning the 2022 Plasticblitz should be bigger than ever! The Rotary End Plastic Soup campaign started in Amsterdam in 2016 and is now operated by Rotary Clubs in 42 countries world wide.

Results from the 2021 Plasticblitz
The first plasticblitz was run last year as a successful trial project
In total, 10 Environment Agency teams and 7 community groups took part. These groups carried out 26 litter picks covering nearly 28km of river bank whilst collecting data on the type of waste encountered. 166 people took part in these events, with groups completing the equivalent of 57 hours of continuous litter picking. In total, 139 bin bags were filled, with 29 of these sent for recycling. A total of 6557 items of waste were categorised from the Thames and its Tributaries, with 72% of this waste made of plastic. The worst offending items were drinks cans (941), plastic drinks bottles (819), cigarette stubs (626) and crisp packets (533).
The challenge is on for the 2022 Plasticblitz to exceed these numbers!
The Method...
All Plasticblitz litter picks should take place between the 17th and 25th September 2022. You must follow a set method to collect data for the Plasticblitz project. This method will depend on whether you are carrying out the litter pick from the bank or from a boat. There is a separate method for Environment Agency staff who are collecting litter from locks and weirs.
Scroll down to find the right method for you.
Bank based blitz
Follow the following steps to complete a Plasticblitz survey from the river bank:
- Mark out an area of river bank of set length and width. You will carry out the Plasticblitz survey within this area. The area of river bank you choose to clear will depend on how much litter there is. Choose a smaller area if the bank is significantly littered.
- Record the length and width of the bank you decide to carry out the Plasticblitz survey over.
- Pick all the waste within your set area (plastic and other), counting and recording each item as you go on page 3 of the survey123 form or printed data sheet (if the latter is chosen, the data will need to be uploaded to the survey123 form on completion of the litter pick). It's sometimes helpful to do this as a pair, with one person picking and one person recording.
- Outside of this defined area, a general litter pick can take place. The aim here is to simply pick as many bags as possible. Try to bag plastic bottles and drinks cans separately so they can be sent for recycling.
- As you carry out this litter pick, record what the top three brands you encounter are.
- Leave filled bags by an easily accessible public bin for collection by you local council. For larger picks, it may be necessary to arrange for collection of the waste in advance with your local council.
- Top Tip: For larger groups, it might help to split into two teams. One team can focus on collecting the data in the Plasticblitz area, whilst the other team carries out a general litter pick across the rest of the bank.
Boat based blitz
Follow the following steps to complete a Plasticblitz survey from a canoe or kayak:
- Mark out a set length of river bank, over which you will carry out the Plasticblitz survey. The length of river bank you choose to clear will depend on how much litter there is. Choose a smaller length if the bank is significantly littered.
- Record the length of bank you choose to carry out the Plasticblitz survey over.
- Pick all the waste from this length of bank, collecting it into bin bags.
- Carry out a general litter pick to clear the wider bank outside of this area. Collect as many bags of waste as possible (remembering to keep these bags separate from those collected on the set transect length of bank!).
- On returning to the bank, the bags collected from the set transect length should be carefully emptied and sorted through, with the types of waste collected recorded on the survey123 app or printed data sheet (if the latter is chosen, the data will need to be uploaded to the survey123 form on completion of the litter pick).
- When sorting and recording the litter, the top three most polluting brands should be noted down.
- Remember to record the total number of bags you fill across the entire day (from both the transect area and wider bank) and to recycle any clean bottles and cans!
- Leave filled bags by an easily accessible public bin for collection by you local council. For larger picks, it may be necessary to arrange for collection of the waste in advance with your local council.
Environment Agency Teams
Note: Weirs, locks and trash screens are hazardous structures and therefore should not be cleared by members of the public. These structures should be cleared by trained Environment Agency staff only.
- Environment Agency staff should pick a time between the 17th and 25th September to carry out their survey (ideally when a significant amount of litter has collected within their chosen structure or stretch of river).
- Environment Agency staff should use a long handled net or rake to clear the build-up of waste that gathers within a weir, lock, trash screen or stretch of river.
- Waste should then be carefully emptied on the bank and sorted through.
- The types of waste collected should be recorded on the survey123 app or a printed data sheet (if the latter is chosen, the data will need to be uploaded to the survey123 form at a later time).
- The waste should then be re-bagged and appropriately disposed of (remember to recycle any clean cans and bottles!).
