We all know that sustainability matters. We’ve seen the headlines, watched the documentaries, maybe even followed a few climate activists on social media or shared an infographic about plastic waste. But knowing isn’t the same as doing—and in a world facing urgent environmental challenges, doing is what counts.

So how do we move from awareness to meaningful action? The answer might be simpler, and more hands-on, than you think.

At GreenUp, we’ve found that real change begins when people step into sustainability with their own two feet. Whether it’s cooking with rescued food, joining a cleanup effort, or exploring how waste can be given a new life, these experiences make sustainability feel real. They shift perspectives, spark curiosity, and often stay with people long after the day is over.

This blog explores why hands-on learning is such a powerful driver of sustainable change. It also shares how GreenUp’s workshops and interactive sessions are helping individuals and organisations across Switzerland bring that change to life.

Why Hands-On Learning Works

Sustainability isn’t always easy to grasp. It’s a big word, tied to even bigger systems, such as climate, food, waste and biodiversity. For many people, it can feel distant, abstract, or even overwhelming. That’s where hands-on learning makes all the difference.

When we do something—plant a seed, sort waste by hand, prepare a meal from rescued ingredients—we stop thinking of sustainability as a theory and start relating to it as something personal and possible. The experience becomes a turning point. It’s no longer just information we’re processing; it’s something we’ve lived through, something we’ve felt.

This isn’t just intuition – it’s backed by research. Studies in environmental education show that experiential learning increases retention, deepens understanding, and strengthens emotional engagement, all of which are key to lasting behaviour change. When people are actively involved, they’re far more likely to remember what they learned and apply it in their daily lives.

Emotional connection also plays a powerful role. Programs that involve nature-based or community activities often see participants walk away not just more informed, but more motivated and confident in their ability to contribute to change. Even one well-designed, hands-on experience – like a sustainability workshop or an outdoor cleanup – can shift attitudes and plant the seed for long-term action.

That’s why experiential learning works so well. It connects the dots between knowledge and action. It helps people go from understanding a problem to believing they can be part of the solution.

GreenUp in Action: Workshops That Make a Difference

It’s one thing to talk about how hands-on learning works. It’s another to see it in motion. At GreenUp, our workshops are designed to make sustainability feel real and relevant. They create opportunities for people to engage directly with environmental issues, using practical, creative activities that lead to new insights and habits.

Each session combines interaction, reflection, and action. Participants don’t just receive information—they experience it, and they leave with a clearer understanding of how their choices connect to the wider world. Here’s how that learning comes to life:

Circular Champions

Resources are limited—but creativity isn’t. This workshop introduces the principles of a circular economy through a mix of conversation, hands-on demonstrations, and a visit to a local circular project. Participants explore how to reduce waste at the source and repurpose materials in ways that save money, lower emissions, and encourage innovative thinking.​

The need for circular approaches is increasingly urgent. According to the Circularity Gap Report 2023, only 7.2% of the materials we use globally are part of a closed-loop system—meaning over 90% of extracted resources are wasted after a single use. This linear “take–make–waste” model contributes significantly to climate change, biodiversity loss, and pollution. Shifting toward a circular economy helps address all three by keeping materials in use and reducing our reliance on virgin resources. ​

Instead of abstract ideas, the group works with real-world examples—trying out minimal-waste products, testing practical tools, and seeing how circular solutions work in everyday life. The experience helps shift mindsets and opens up new ways of thinking about value, consumption, and design.

Nature Keepers

This outdoor workshop focuses on the environmental impact of waste, particularly on soil, water, and biodiversity. Participants head outside for a group cleanup, combined with an exploration of how litter affects local ecosystems.

Litter doesn’t just spoil the view—it disrupts entire ecosystems. As it breaks down, it can release microplastics and toxic substances into soil and waterways, affecting wildlife and plant health. According to the UN Environment Programme (UNEP), litter—especially plastics—is a key driver of biodiversity loss, with serious implications for both terrestrial and marine environments. Improper waste management contributes to habitat degradation, pollutes freshwater systems, and endangers thousands of species.

The act of physically removing waste from natural areas creates space for meaningful reflection. People often come away with a renewed sense of connection to the environment and a better understanding of the role they can play in protecting it. The activity also builds a sense of teamwork and shared purpose, making the learning both personal and social.

Food Futures

Together, the group prepares a snack from surplus ingredients, discusses food choices, and visits a local food initiative making a positive difference. The experience combines practical skills with reflection and curiosity. It encourages people to rethink their habits and explore how food can be a joyful, powerful part of living more sustainably.​

The environmental footprint of our food system is substantial. According to a study published in Nature Food, food systems were responsible for 34% of all human-caused greenhouse gas emissions in 2015. The largest contribution came from agriculture and land use/land-use change activities, with the remaining emissions from supply chain activities such as retail, transport, consumption, fuel production, waste management, industrial processes, and packaging.

This workshop is not only informative—it’s also a meaningful shared experience. As Stephanie Scheller, Hospitality Manager at FELFEL, shared after a recent Food Futures session in Zürich:

“The short version of the workshop ‘Food Futures’ by GreenUp was both educational and a great team bonding opportunity. Full of passion and joy, GreenUp shared their knowledge with us and gave us ideas for a more sustainable lifestyle!”

More Ways to Engage: Talks and Games

Not every organisation has the time or capacity for a full-day workshop. That’s why GreenUp also offers shorter, flexible formats that make sustainability accessible – even in the middle of a busy workday.

Our 30-minute talks and three-hour games are designed to spark interest and plant the seeds of change. They work well as part of team events, sustainability days, or even just a morning meeting with a twist. The focus is on participation, curiosity, and creating a moment of connection to environmental topics.

Talks

These focused sessions dive into key sustainability themes—like food, fashion, or plastic waste—without overwhelming participants. In half an hour, we unpack the environmental issues tied to everyday habits, share practical insights, and open space for discussion.

Because the sessions are concise, they’re ideal for teams looking to build awareness or kick off wider sustainability efforts. Even within a short time, participants often come away with new perspectives and ideas they’re eager to explore further.

Games

For teams who want something more interactive, our games offer a light but effective way to engage. Activities like sustainability bingo or a lucky-wheel challenge bring environmental topics into a playful, social setting.

These games are designed to be inclusive and energising. They create opportunities for people to learn from one another, discover surprising facts, and enjoy a shared experience that builds team spirit. Importantly, they also open the door to deeper conversations—without ever feeling like a lecture.

Why Organisations Choose GreenUp

Creating a culture of sustainability at work can feel like a big task—but it starts with simple, shared experiences. GreenUp supports organisations by making sustainability engaging, practical, and relevant to real workplace life.

Since 2020, we’ve worked with companies and institutions across Switzerland to bring sustainability to life through action-based learning. Our team combines deep knowledge of environmental topics with a genuine passion for making change feel possible. We understand that every organisation is different, which is why we offer flexible, customisable formats that fit your team, your goals, and your schedule.

What sets GreenUp apart isn’t just what we teach—it’s how we teach it. Everything we offer is designed to get people involved, not just listening. Our sessions are built to encourage connection, collaboration, and shared purpose. They’re grounded in current science and real-world solutions, while maintaining a positive tone that focuses on possibilities rather than guilt or overload. Above all, they’re memorable—rooted in hands-on activities that leave a lasting impression and inspire people to take what they’ve learned into their daily lives.

Organisations that work with GreenUp often find that something shifts. Teams start to speak the same language around sustainability. Ideas surface that weren’t there before. And most importantly, people feel inspired to act—not just because they have to, but because they want to.

Whether you’re building momentum for your sustainability strategy or simply starting the conversation, GreenUp provides the spark that helps teams move forward.

Conclusion: Small Actions, Big Shifts

Sustainability doesn’t begin with sweeping policies or global declarations—it starts with small, intentional actions. The kind we take when we understand the issues not just in theory, but through experience. That’s where hands-on learning makes a real difference. It helps people see the impact of their choices, feel connected to the bigger picture, and gain the confidence to act.

At GreenUp, we’ve seen how a morning spent cooking with rescued food or cleaning up a local park can stay with people for months—sometimes years. These experiences build momentum. They shift habits. They turn good intentions into meaningful steps, and often spark bigger changes within teams and organisations.

By creating space for curiosity, participation, and creativity, our workshops and activities open the door to a more sustainable way of working and living. It’s not about being perfect—it’s about getting started.If you’re ready to make sustainability part of your workplace culture, we’re here to help.

“We cooked a strange dessert”.This is one feedback we got after our Food Futures workshop last week in Laax around sustainable food, as we chose to make a vegan version of the French pain perdu, the French toast with recovered bread as an example of a recipe against food waste. In this workshop, we usually kick off by looking at facts around food production and consumption: did you know that the global food system is the single biggest contributor to climate change, causing 1/3 of global greenhouse gas emissions? We then question our food choices and brainstorm about sustainable solutions and actions to the food challenges we face today. Among those solutions, reducing food waste is key. According to the United Nations[1], almost 1 billion tons of food – 17 percent of all food available to consumers worldwide – goes into trash bins every year. Producing, transporting, and letting that food rot contribute more than 8 percent of global greenhouse gas emissions. If food waste were a country, it would be the third-largest emitting country in the world. Good news is, as consumers, we can play a part in reducing the greenhouse gas emissions related to our food system by starting buying less and reducing (eliminating?) our food waste. That is why our Food Futures workshops always involve hands-on preparing of foodsave recipes. For this occasion we even cooked a whole meal together. What could be more satisfying than being able to measure, in your own kitchen, your impact on food waste solutions and the reduction of CO2 emissions?

A brief history of pain perdu

The history of French toast dates back to Roman times, when this dish was already consumed to avoid wasting stale bread. Over time, the recipe spread throughout Europe and evolved, giving rise to different variations depending on the country and era, and is now even offered in gourmet restaurants where chefs continually reinvent the recipe. The basic recipe involves soaking stale bread in milk, eggs, and sugar, then frying it and serving it with sugar, spices, fruits, or jam. Although the French toast is called French toast, it does not only exist in France. The English recipe closely resembles the French version, with bread dipped in a mixture of milk, eggs, and sugar, then fried in butter. However, the English have a tradition of adding cinnamon and nutmeg to enhance the flavor of the dish. French toast is often served for breakfast, accompanied by maple syrup, fruits, or bacon. In Spain, French toast is known as torrijas. Torrijas are traditionally prepared during Holy Week, a fasting period for Christians. The Spanish recipe differs slightly from other European versions. The stale bread is soaked in milk or sweet wine, then in beaten eggs, before being fried in oil. The torrijas are then sprinkled with sugar and cinnamon, offering a unique sweet and spicy taste. In Germany, it’s called Arme Ritter, which means “poor knight”, and refers to a meal that can be prepared with limited financial means using inexpensive ingredients. In Portugal, French toast is a traditional Christmas dish called rabanadas. Contrarily to the French who considered this bread was, if not cooked, lost (“perdu”), the Dutch language seems to have a more positive view as French toast is called gewonnen brood (“gained bread”, since it is recovered), and that’s under this name that it can be found in Belgium or wentelteefjes in the Netherlands.

Are old recipes the new weapon to tackle food waste?

Originally a way to avoid wasting stale bread, French toast is, at least in France, a dessert that has definitely become a classic and that can even be found today on the menu of some gourmet restaurants. Easy to make, yummy and trendy, it seems that this could help us change the way we see food waste. And thanks to the Dutch, who are definitely our narrative changer just starting with the name!
