B.15 Recycling Acrylic Waste with REFLO at Floreeda Fabrications

In any design workshop, managing waste is an ongoing challenge, especially when the waste produced isn’t in large enough quantities to interest commercial recyclers. In the B.15 workshop, one of our waste management responsibilities is to deal with Acrylic offcuts and waste produced through student modelmaking, most notably from laser cutting activity. Whilst the quantities may be small by industrial standards, the impact adds up over time and it has always been our intention to find a solution to this waste stream.

For several years the team have stored acrylic waste in the hope of finding a sustainable solution as opposed to the general waste route which many workshops often default to. A key complication is that Acrylic (PMMA) cannot be recycled with general plastic and requires a specialised process. Most local recycling services are not equipped to handle it and the services that do, often recycle the waste at sites abroad. After exhausting conversations with recycling companies coming up with no useful solution, we turned to a trusted local supplier, Floreeda Fabrications.

 

We found that Floreeda had been developing an initiative called REFLOW – a process that allows for in-house acrylic recycling. This takes end of life acrylic parts and recycles them through a clean manufacturing process with no additives, turning them into new, useable sheet material. This promotes a circular and closed loop economy within the industry.

We’re now thrilled to say that we’ve received our first batch of recycled sheet material made entirely from the waste we had been storing over the years. Some of this recycled material has already been put to use, forming part of our B.15 Modelmaking award trophies that were handed out to this years student winners at the Manchester School of Architecture 2025 Degree Show.

Looking ahead, we’re excited to see how our students will incorporate the new REFLOW Acrylic into their work. Not only does the material perform like the original, but its origin gives it a story of sustainable thinking and responsible design. We also look forward to collaborating further with Floreeda to explore what other acrylic mixes and colours might be developed from our collected waste in the future.

This partnership represents more than just waste reduction; it’s a model for sustainable collaboration between education and local industry. This small but symbolic step shows how material circularity can be embedded into the culture of making. We hope it inspires others to consider how taking responsibility for even small-scale recycling can have a real impact, showing that patience and persistence to find solutions pays off.

A visit to la Facultad de Arquitectura y Urbanismo, Universidad Central del Ecuador, Quito – Patricia Belcin

During December 2019 I visited la Facultad de Arquitectura y Urbanismo (the Faculty of Architecture and Urbanism) part of Universidad Central del Ecuador, in the country’s capital, Quito. At 2980m altitude, the beautifully designed brutalist building of the faculty felt like a hidden gem among the other buildings from the university campus, the semi-circular repetitive roof structures transmitted an equilibrium very fitting for a place dedicate to design and architectural education.

While talking to a first year architecture student I understood that in the early stages a big emphasis is put on developing hand drawing skills and the designs are tested through simple hand crafted models. I was impressed of the amount of models the students were producing, and how they were finding enough time to invest in this as the course content was broader than what I had experienced during my Part 1 in the UK.

The main reasons for this were the materials and methods being used. After observing only a few models I noticed that balsa wood is everyone’s favourite material. This soft fibre wood allowed the students to quickly craft sketch models, quick prototypes and many times it was used even for the final presentation models. The ease with which this material can be manipulated allowed the students to recreate the workshop environment in their homes and with only a scalpel and some glue they were constructing a wide variety of models. Sometimes for the final exhibition models the faculty’s laser cutter was used for achieving more precise cuts on fine details.

It’s no accident that balsa is used so extensively as it is a locally grown material which is widely available at a very low price (I noted it was approximately 10% of the price at which we purchase balsa in the UK). Balsa is a native species to Ecuador and the country is the world’s leader in balsa production, with over 90% of the wood being exported all over the world. Because of the county’s altitude, climate and environment, the balsa from the Ecuadorian forests is privileged as it offers a more stable wood in terms of density. Balsa is not an endangered species due to its fast growth and facility of reproduction.

This made me reflect upon how we sourced materials during the projects which I undertook at MSA. Few projects asked us to consider the usage of local materials, and when we do consider it, this is mostly seen as a constraint. However, not very often do the students question from their own initiative the provenience of the materials which they use, especially in a world where everything is available at a few clicks away. From my observations gathered whilst visiting the architecture school in Quito, I noticed that the use of local materials is widening the possibilities in terms of modelmaking and construction. By using these materials so often the students developed skills which allowed them to create a wide variety of models by understanding the different properties of the wood.

While visiting an exhibition with projects from the masters of architecture course I noticed several models which used plaster or plywood, therefore being more developed in terms of material complexity, but the combination with the balsa wood was omnipresent. In the project from the below images, the student used a series of volumetric plaster models which were combined with red painted key elements of the design. The red colour was then used in the sectional model of the final design and within the architectural drawings as a highlighting method.

Apart from testing design concepts through models I noticed the importance of the technical side within their architecture degree. An application through modelmaking was the project visible in the images from below, where groups of students tested different types of joints which could be used in creating a geometrical sphere. Several methods of joining the wooden pieces were tested, including connections that used sections of recycled plastic pipes or tubes, as well as using bespoke metal fixings which were screwed into the wood. Regardless of the complexity, these constructions were built with only using basic tools and local materials.

Being exposed to the modelmaking culture of the architecture school in Quito was a good lesson about the importance of valuing local practices and materials and making the most of what resources  you have to hand. Perhaps the ease with which we can access materials produced all over the world here in the UK makes us, unintentionally, a bit ignorant of the energy and effort it takes to produce them. As a result the profession is quite wasteful. It would be an interesting project set out to find the local equivalent of the balsa wood source in Ecuador right here and incorporate it into our models. This would be both convenient and more sustainable, helping to reduce our carbon footprint as we progress through architecture school.
