How to Get People to Recycle More at Work
Why positive messaging works better – and why the subconscious holds the key
Recycling should be one of the easiest pro-environmental behaviours to adopt at work. Most employees say they care about it, most organisations say they support it, and most workplaces now provide recycling facilities. Yet the gap between intention and action remains stubbornly wide.
The UK’s household recycling rate remains largely unchanged at around 44-45%, despite years of awareness campaigns and investment in infrastructure.
At the same time, confusion remains a major barrier. The UK government’s new Simpler Recycling reforms were introduced specifically to address widespread uncertainty about what can and cannot be recycled, acknowledging that inconsistent systems have contributed to ongoing confusion among households and workplaces alike.
Research from WRAP also shows that while 90% of people say they regularly recycle, more than three quarters admit they still throw recyclable items into general waste.
So why does this gap between intention and behaviour persist? And what actually works to shift behaviour?
To find out, we partnered with Ceris Burns International, specialists in environmental PR, to explore whether different types of recycling messages could change attitudes – especially at the subconscious level, where so many day-to-day decisions are made.
Simpler Recycling
The challenge has become so significant that the UK Government introduced Simpler Recycling reforms across England. From March 2025, workplaces with 10 or more employees have been required to separate core recyclable materials and food waste, while from March 2026 local authorities must provide a more consistent recycling system for households. The aim is simple: reduce confusion by ensuring people can recycle the same core materials whether they are at home, at work, or in public settings.
This matters because one of the biggest barriers to recycling isn’t motivation, it’s uncertainty. For years, different councils and organisations accepted different materials, creating what policymakers described as a recycling “postcode lottery”. Simpler Recycling seeks to remove that friction by creating a more consistent national standard.
From a behavioural science perspective, this is exactly the right approach. People are far more likely to perform a behaviour when it is easy, familiar, and requires little conscious effort. Standardising recycling systems reduces the cognitive load involved in deciding what goes where, making the desired behaviour more likely to occur.
Why emotions and framing matter more than we think
Behavioural science has long shown that how a message is framed can dramatically influence how it lands. Negative messages – highlighting threats, losses or consequences – can grab attention because our brains are wired to respond quickly to potential danger.
But negative messages don’t always change behaviour.
In some contexts, especially when outcomes aren’t personally risky or when people feel disengaged from an issue, positive messages can be more effective. They reinforce aspirational associations, create a sense of shared identity, and make the desired behaviour feel rewarding rather than punishing.
We wanted to test which approach works best for recycling in the workplace.
Measuring subconscious attitudes – not just stated intentions
Recycling carries strong social desirability. Most people say they plan to recycle more… but their behaviour doesn’t always follow. That’s why we used an Implicit Association Test (IAT) – a tool designed to capture subconscious associations that people may not openly express, or may not even be aware of.
The study design was straightforward:
- 200 UK adults completed questions about their existing recycling habits and attitudes.
- They were then shown either positive or negative messages about recycling.
- Immediately afterwards, they completed an implicit test measuring how strongly they associated recycling with “importance.”
- Finally, they reported their intentions to recycle in the future.
This allowed us to compare what people say they intend to do, with what their intuitive responses suggest they actually feel.
What we found – the subconscious tells a clearer story
1. Positive messages strengthened subconscious beliefs about the importance of recycling.
Participants who saw positive, hopeful messaging developed stronger implicit associations between recycling and importance than those who saw negative messages.
In other words: uplifting messages shifted deeper attitudes more than threat-based ones.
2. This effect was strongest among the people who needed it most.
The biggest shift occurred among participants who:
- thought recycling was less important,
- believed it was less effective, and
- reported recycling least often.
For this group – the hardest to reach – positive messages had a significantly greater influence on subconscious attitudes. That’s a powerful insight for anyone designing workplace sustainability communications: positivity doesn’t just “preach to the converted”; it reaches the unengaged.
3. But conscious intentions didn’t change.
Despite the strong implicit effects, there were no differences between message types in people’s self-reported intentions to recycle more in future.
This contrast highlights why implicit measures matter. Traditional self-report alone would have suggested “no impact.” The implicit data shows the opposite: the messaging had a real, meaningful psychological effect – one that people may not yet consciously recognise.
Why this matters for real-world behaviour
Subconscious shifts are important because they shape the micro-decisions people make every day – especially in environments like offices, where recycling often happens quickly, automatically, and with minimal deliberation.
When recycling feels important at a subconscious level, the brain becomes more likely to default to the recycling bin rather than the general waste bin, particularly under time pressure or distraction.
The takeaway is clear:
If you want employees to recycle more, focus on positive, benefit-led messaging, not guilt or threats.
Practical steps for encouraging recycling at work
Based on the findings – and what we know from behavioural science – here’s what really helps:
- Use positive, hopeful messaging that highlights the benefits of recycling and promotes a sense of shared responsibility.
- Support behaviour with clear infrastructure. Simpler Recycling recognises that people cannot recycle effectively if systems are inconsistent or difficult to navigate. Consistent bin colours, clear signage and unambiguous instructions reduce friction and make recycling the easy choice.
- Reduce uncertainty. Make “what goes where” unambiguous – confusion is one of the biggest barriers to action.
- Make sustainability part of the culture. When leaders model the behaviour, norms strengthen; when norms strengthen, behaviour follows.
- Don’t rely on stated intentions alone. Look for deeper indicators of change – whether through implicit research or real-world behavioural data.
In summary
Positive recycling messages don’t just make people feel good – they reshape underlying attitudes, especially among those least engaged. And while people’s stated intentions may not shift immediately, the implicit data shows that the seeds of behaviour change are planted beneath the surface.
Combine optimistic messaging with clear, easy recycling infrastructure, and you have a recipe for meaningful, lasting change in the workplace.
