About the hackathon

The LOTUS Open Innovation Hackathon is a 3-day, all-digital event that brings together students, researchers, startups, and university staff to co-create solutions that respond to real sustainability and digital transformation challenges inspired by the United Nations Sustainable Development Goals.

Across Europe, universities play a growing role in driving green and digital transitions, but many innovation ecosystems remain fragmented. This hackathon strengthens collaboration between academia, students, and external partners to turn ideas into impactful solutions.

Through a dynamic mix of expert workshops, mentoring, teams’ co-creation and live pitching sessions, participants will refine their project ideas and transform them into validated, actionable blueprints.

Challenge Portfolio

Towards Zero-Waste Universities

Higher education institutions generate large amounts of waste — from food packaging and office materials to laboratory disposables. While sustainability pledges are growing, practical waste-reduction systems often lag behind. The challenge is to design smart, scalable, and data-driven solutions that help universities and organizations transition toward zero-waste operations, reducing, reusing, and tracking resources more efficiently.

Inspiring business models of real companies:

  • Rheaply — Circular-asset exchange used by universities to redistribute surplus equipment/furniture and avoid new purchases; documented higher-ed reuse savings.
  • Warp It — Institutional reuse portal widely adopted by UK universities (e.g., UCL, Oxford, Exeter) to keep assets in circulation.
  • Winnow — AI vision + smart scales to cut kitchen food waste in education and contract catering.
  • RECUP / REBOWL — Germany’s largest reusable cup/bowl deposit system for campus and city food-service partners; each cup/bowl replaces hundreds of single-use items.
  • TerraCycle Zero Waste Boxes — Campus programs for hard-to-recycle streams, incl. labs.

Green Mobility for Everyday Life

Mobility is a major contributor to emissions, congestion, and energy waste — both on campuses and in urban areas. The challenge is to develop solutions that make sustainable commuting and local travel the default choice. Ideas should make low-carbon mobility practical, trackable, and attractive to individuals and organizations alike.

Inspiring business models of real companies:

  • Via — Runs demand-responsive transit and campus/corporate shuttles across Europe; partners with public agencies and universities to shift trips to shared, low-emission services.

Frequently asked questions

Teams of 2 or more members composed of students, researchers, startups, or staff (academic or non-academic), from anywhere around Europe. Cross-disciplinary teams are strongly encouraged.

No, unfortunately not. The LOTUS Hackathon is designed for teams with existing ideas. Individual matchmaking is not part of this event.

Each team may apply with one idea only, addressing one specific challenge from the official LOTUS Hackathon Challenge List.

Your idea should propose an innovative and feasible solution aligned with one of the published challenges. It can be a new concept, a prototype, or an early-stage project that can be developed further during the hackathon.

When applying, teams will choose one challenge that best fits their idea’s focus. The challenge list is available on the Hackathon website.

The hackathon takes place fully online over three consecutive mornings, featuring workshops, mentoring, and collaborative team work. A final pitching session will follow, where finalists teams will be invited present their solutions to an international jury.

Participation is free of charge for all selected teams.

Your team will gain access to expert mentors, interactive workshops, and digital collaboration tools. Mentors will guide you through value proposition design, business modelling, and pitching preparation.

An international jury will evaluate all final pitches based on:

  • Innovation & originality
  • Relevance to the selected challenge and SDGs
  • Feasibility & scalability
  • Team presentation & collaboration

Winning and high-potential teams will continue receiving personalised mentoring through the LOTUS Mentoring Service and may be invited to join acceleration or showcase activities supported by the LOTUS consortium.
