Learnings from the Fall 2024 Prototyping Fund Showcase

CAFECO

Sustainable, biodegradable to-go cups – an eco-friendly solution that supports local cafés, reduces waste, and promotes a circular economy.

How we built it
We tested various materials in the lab, finalizing a mix of coffee grounds and biopolymers. Customization is done with a DHOLETEC DT 1000 laser engraver.

How the prototyped evolved since the 1st cycle
On round 1 of the prototyping fund, we learned how to identify the most important functionalities for our product. On round 2 of the prototyping fund we were able to develop a second product and focus more on the UX design of our solutions.

Top lesson learned
Testing showed the importance of balancing durability and eco-friendliness, guiding us to a coffee ground-biopolymer mix for a sustainable, functional product.

DIGNOTA

Digital Documentation Always Within Reach

A secure digital storage system for life’s most essential documents that allows you to maintain control of your identity and livelihood while on the go.

How we built it
Designed from interviews with immigration lawyers, refugees, and social workers, the main concerns were the importance of consistent, secure access and ease of use.

Top lesson learned
Learning what the most essential, and simplest features of the product were so that they could be tested and refined rapidly to adapt the product.

ETERA

The project turns plastic waste into durable building blocks as an eco-friendly alternative to environmentally harmful materials, offering a quick solution to plastic pollution and housing shortages. 

How we built it
The collected plastic is sorted, shredded, and cleaned. It is then compressed into a mold and briefly heated with heating rods to stabilize the form.

Top lesson learned
Air chambers in plastic blocks enhance strength and insulation, making them more durable and efficient as a building material

Project HOMELORE
(all star awardees)

Empowering immigrant women in Lisbon through exploring folk art and textile production: Uncovering their stories and building pathways to employment.

How we built it
The hypothesis explored immigrant women’s experiences in Lisbon and their work outlook through folk art, specifically embroidery. A 2-day workshop with women from the Indian Subcontinent tested this, now expanded into a continuous course currently based at Lisbon Project.

Top lesson learned
This prototyping aimed to craft a visual language for our brand’s future. Many participants knew traditional embroidery techniques, easing our process.

How our prototype evolved
In the Spring’24 PF, we explored motivation toward work and folk crafts. With that confirmed, round two focused on quality control. Diving into four specific embroidery techniques, we aimed to refine product-market fit, identify process gaps, upskill participants, and test quality limits.

SEEDS

A project to develop a menstruation dignity product with two key criteria: no water usage in its production or use, and economic value generation. We advanced in this purpose through co-design and prototyping workshops.

How we built it
We received mentorship to refine our human-centred approach, we collaborated with local NGOs and conducted three workshops with urban and rural women from Colombia’s Caribbean region.

Top lesson learned
Learning what the most essential, and simplest features of the product were so that they could be tested and refined rapidly to adapt the product.

SHROOM JERKY

A mushroom-based vegan jerky that offers health-conscious consumers a sustainable, climate-friendly alternative to beef jerky.

How we built it
Made at home using a dehydrator and mixer: the mushrooms were cooked, marinated in a custom blend, and dehydrated to achieve the desired texture and flavour.

Top lesson learned
The importance of selecting the right mushroom type and pre-cooking it and mixing it into a paste before dehydration to eliminate the earthy taste and enhance flavour.

PROJECT UNFOLDED

An interactive workshop format on empathy for Masters students designed using storytelling and collective reflection exercises to foster emotional awareness, team building and deeper relationships.

How we built it
Developed as an interactive workshop with theoretical intro and guided storytelling and reflective exercises, tailored to deepen empathy and strengthen team values.

Top lesson learned
A focused target group amplifies impact – the CEMS program’s shared goals and CEMS students’ diverse backgrounds made them ideal targets for our workshop pilot.

WASTED GIN
(all star awardees)

Transforms surplus bread into a bold, eco-conscious spirit. Merging classic London Dry with vibrant Portuguese orange, each bottle fights food waste and cuts CO2 emissions.

How we built it
Distilled from surplus bread with a hint of Portuguese orange, our gin offers bold flavor and a step toward sustainability with every sip.

Top lesson learned
1. Working with experts grew our knowledge and creativity.
2. Driving product development forward, regardless of any setbacks

How our prototyped evolved
Our focus was on perfecting the gin’s flavor profile, working with a small distillery to test recipes and processes, then hosting tasting events for feedback.

WASTE TO LIGHT

Unique, handmade Mycelium biocomposite desk lamps made of NÃM’s Urban mushroom farm waste.

How we built it
The shiitake mushroom substrate is revalorized into a mycelium biocomposite. The biocomposite
is dried, carved, and transformed into a design desk lamp.

Top lesson learned
The less transformation steps the better. Be fast, try as much prototypes as possible and gather feedback whenever you can.
