Utilizing AI and a wholesome dose of inventive considering, the Neat Streets marketing campaign has helped to scale back litter by as much as 75 per cent in Bournemouth, England. Now the method is being efficiently deployed elsewhere
It’s summer season 2022, the most well liked on report, and a few 55,000 folks have descended onto the seashores at Bournemouth. Most have introduced all the pieces they may want for the day: meals, drinks, suncream, towels, procuring luggage, nappies, cigarettes. Then the solar goes down and the beachgoers go away.
Seagulls swoop in and peck at what’s left behind. It isn’t fairly. On a busy day, guests to Bournemouth can generate as much as 15 tonnes of litter. Throughout summer season weekends, the seven-mile-long stretch of sand is normally heaving with folks. By nightfall, the shoreline seems like a landfill website. Empty beer cans, plastic lids, disused napkins, used nappies, fag ends.
In Could 2021, Bournemouth noticed a 476 per cent rise in litter throughout one of many financial institution vacation weekends, in contrast with charges seen in lockdown. To fight the difficulty, the council unveiled a £3.5m ‘seasonal response plan’. The native newspaper, the Bournemouth Echo, appealed to its readers for options too. Extra bins! Extra fines! Extra litter pickers!, residents prompt. “Don’t clear it up for a month and see if folks nonetheless need to come,” advocated one other.
However for all their goodwill, these had been concepts that had failed earlier than. The council had employed further employees. That they had put in further bins. Enforcement officers hadn’t fined anybody for littering within the final 12 months. They wanted to attempt one thing new.
By the top of the summer season, litter was down by a median 75 per cent. All the realm wanted, it appeared, was just a little little bit of ABBA.

Litter: selecting by way of the information
Bournemouth didn’t turn out to be an excellent trouper in litter discount in a single day. First, the council introduced in Hubbub, an environmental charity that had beforehand used behavioural change analysis to deal with littering. Hubbub then prompt environmental monitoring firm Ellipsis Earth undertake a litter survey over a six-month interval so they might see precisely what they had been up towards.
The London-based firm analysed pictures, video and drone footage to substantiate what garbage was being dropped. Their software program might gather a number of miles of images in minutes. It then used AI to find out the burden, quantity, environmental influence, carbon footprint and recycling worth of every piece of litter.
“Our litter recognition know-how can quickly scan photographs and movies to determine 47 completely different classes of litter,” says Ellipsis Earth founder, Eleanor Mackay. It may possibly additionally determine hotspots and key patterns of littering throughout areas.
The staff discovered that individuals dropped litter each three seconds, and that garbage would then stay on the bottom for six hours – or eight hours on the seaside.

“We noticed immediately that the kind of litter being dropped was very particular to the day of the week and the placement,” says Mackay. “Friday and Saturday nights noticed extraordinarily excessive ranges of alcohol- and drugs-related littering on the rear of the town centre seashores.
“In distinction, Sundays and financial institution holidays noticed massive portions of family-related littering on the water’s edge, like nappies, juice packing containers and children toys,” she provides. “These things had been left on the seashores in a single day and subsequently washed into the ocean by the excessive tide.”
They took their findings again to Hubbub, which used behavioural change analysis to deal with the littering. Collectively they launched Neat Streets in 2021, an anti-littering marketing campaign throughout Bournemouth, Christchurch and Poole. It received gold in the perfect campaign of the year class on the Global Good Awards 2022, which honours companies, NGOs and charities that obtain sensible, real-world impacts in sustainability.
From finger-wagging to enjoyable
“Traditionally the tone [around littering] has been just a little bit draconian,” says Hubbub director, Gavin Ellis. “The method we took was to undertake a way more constructive, playful tone as a result of that’s what folks reply to.”

So, out went finger-wagging and £150 fines and in got here extra constructive interventions. Hubbub launched yellow and silver disco bins that performed music by ABBA, amongst different selection tunes, at any time when somebody deposited litter. They put in glow-in-the-dark bins in unlit areas. Bigger, brightly-coloured refuse containers had been positioned near smaller bins.
“Working with Ellipsis appeared like a superb method of utilizing knowledge to underpin our method,” provides Ellis. “The information meant we might goal particular communications at sure audiences.”
Total, the outcomes had been outstanding: to the east of Bournemouth Pier, the place interventions had been put in, litter diminished by 79 per cent. By comparability, no interventions had been positioned to the west of the pier and no drop in littering was seen.
In Bournemouth Decrease Gardens, historic public gardens that run from the pier to the city centre, the present bins had been the worst-performing ones within the space. So the staff positioned vibrant bigger bins close to the smaller ones, and litter diminished by 89 per cent.
‘Poll bins’ (the place people who smoke answered a query by depositing their cigarette butt; ‘Who’s the perfect footballer? Messi or Ronaldo’) had been connected to lampposts in a number of places too. These minimize discarded cigarette butts by nearly three quarters.
“We’ve demonstrated that this method can have a large influence,” says Ellis, who provides that they’re now in talks with Ellipsis Earth about decreasing roadside litter. “It appears like a step change from earlier approaches however you do want an area authority that’s prepared to be daring and do one thing a bit completely different.”

Among the many councils now shaking issues up are Cardiff and Glasgow, which have requested Hubbub to run comparable campaigns. They’ve partnered with Ellipsis Earth for each. The 2 are additionally working with the native authority in Bristol to develop completely new waste administration methods.
“Our objective is to map each metropolis within the UK to present native councils and waste administration groups the information they should guarantee their operations are as environment friendly and cost-effective as attainable and to scale back littering nationally,” says Mackay.
