Creating Sustainable Brand Activations on Campus

A sustainable campus activation cuts waste at every step: fewer samples sent to the wrong people, packaging students can recycle, digital in place of print, and items people actually keep. Students notice when a brand’s green claims and its giveaways don’t match, so the activation itself has to show the commitment.

Key points

• Students expect brands to act on sustainability as well as talk about it.

• Targeting is the biggest waste saving. A sample that reaches the right student is a sample that does not get thrown away.

• Swap print for QR codes, and give useful, reusable items in place of throwaway merchandise.

• Keep environmental claims specific and provable, in line with the CMA’s Green Claims Code.

• Reusable items get used: 96% of students were still carrying Santander’s 2025 Welcome Bag tote weeks later, according to Santander’s End of Campaign Report (n=50,000).

Why sustainability matters to students

Students are more alert than most to the environmental and social impact of what they buy. Many say they prefer brands that act responsibly, and they read a brand’s choices, from packaging to giveaways, as evidence of what it really values.

That cuts both ways. An activation that leaves a pile of plastic and paper behind undermines any sustainability message the brand carries. One that is visibly careful builds credibility, and students who notice are more likely to mention it to friends.

Budget plays a part too. Students are cost-conscious, so the most sustainable choice is often also the most useful one: something they will use up or keep, rather than something they bin.

Principles for a sustainable activation

Target to cut waste

The biggest source of waste in sampling is product that reaches the wrong person. Distribution planned by hall, city and student profile means fewer samples go unused. Asking students what they thought afterwards shows which audiences valued the product, so the next campaign can be tighter still.

Choose packaging students can recycle

Food and drink brands can use cans, cartons and recyclable wrappers in place of plastic bottles and mixed materials. Personal care brands can move from single-use sachets to trial sizes that students will finish and recycle. Check that anything you call recyclable can actually be recycled in the halls’ own waste streams.

Replace print with QR codes

Flyers and paper coupons are often the first thing to hit the bin. A QR code on the pack can carry the offer, the product story and the sign-up, and it gives the brand measurable data on who acted and where.

Give items people keep

Useful, reusable items stay in use and keep the brand in view. For Santander’s 2025 campaign, Dig In’s Welcome Bag was a Santander cotton tote. 500,000 were distributed, and 96% of students were still carrying them weeks later (n=50,000), according to Santander’s End of Campaign Report. In 2026 the Dig In Welcome Bag is paper. See the Santander 2025 case study.

Run lower-waste events

At campus events, use digital check-in, skip printed handouts and avoid throwaway merchandise such as plastic keyrings and pens. Working with a university’s sustainability team or a student environmental society helps, both for practical advice and for credibility.

Measure without paper

Online surveys replace printed feedback forms and give better data. Dig In has collected over a million survey responses since 2016 through online surveys. See how we measure.

Avoid greenwashing

Students check claims, and so do regulators. The Competition and Markets Authority’s Green Claims Code expects environmental claims to be truthful, clear and backed by evidence. In practice:

• Say exactly what is recyclable, compostable or reduced, and by how much if you know.

• Avoid vague words such as “eco-friendly” or “green” on their own.

• Make sure the activation matches the message. A sustainability claim handed out with a plastic freebie will be noticed.

• Do not claim more than the campaign delivered. If you have not measured the impact, describe what you did rather than what you hope it achieved.

Sampling and sustainability together

Sampling has a natural advantage here. A trial-size product that a student uses up creates less waste than a full-size product they never open, and it lets them decide whether to buy more. The aim is simple to state: the right product, to the right student, in packaging they can recycle, with a digital route to the next step.

It also gives you evidence. A post-trial survey tells you whether students liked the product and whether they intend to buy it, which is a better use of a campaign’s footprint than reach that nobody can account for. Across Dig In’s benchmark of 196 brand surveys for 161 brands since 2018, the median brand scored 85% likely to buy again after sampling (2025, 24 surveys).

A checklist for your next campus activation

1. Define the audience tightly, by hall, city or student type, before deciding volumes.

2. Check every pack and printed item: can it be recycled where students live?

3. Replace leaflets and paper coupons with a QR code and a landing page.

4. Choose any merchandise for usefulness and lifespan.

5. Plan event logistics to avoid single-use materials and leftover stock.

6. Write environmental claims you can prove, and keep the evidence.

7. Survey students afterwards online, and use the results to tighten the next campaign.

Questions brands ask

How can brands make campus sampling more sustainable?

Target distribution so samples reach students who want them, use recyclable packaging and trial sizes students will finish, and replace printed material with QR codes.

Do students care whether a brand activation is sustainable?

Many do, and they notice when a brand’s message and its giveaways don’t match. A visibly careful activation supports a sustainability claim; a wasteful one undermines it.

What giveaways work best for eco-conscious students?

Useful items they will keep or use up, such as reusable bags, bottles or trial-size products. Santander’s 2025 tote was still being carried by 96% of students weeks later (n=50,000), according to Santander’s End of Campaign Report.

Working with Dig In

Dig In plans sampling by hall and city, delivers it in a paper Welcome Bag, and measures results with online student surveys. To plan a lower-waste campus campaign, see product sampling or talk to the team.
