Plastic Reimagined: Exhibition of Circular Design

Circular design is an approach that considers how products are created, used, and reused. It focuses on preserving materials in continuous use by recycling, repairing, or reusing them. In architecture and product design, this principle is adopted to treat nearly non-biodegradable waste, such as plastic, as a resource. These materials are used to create durable products and create systems that allow materials to recycle.

With circular design, architects and designers not only reduce environmental impact but also uncover new creative possibilities in form, function, and material expression. Georgia Tech architecture students have presented an exhibition of recycled plastic furniture at the Atlanta Contemporary. Named Plastic Reimagined: Material Agency & Circular Design, the exhibition presents 13 redesigned chair, each built from recycled HDPE and PLA sourced. These plastic wastes from the Georgia Institute of Technology’s campus waste streams and local recycling facilities.

The initiative from Georgia Tech’s School of Architecture, specifically the course ARCH 6050: Architectural Studio Design + Research by Assistant Professor Hyojin Kwon. As part of the project, students gathered discarded plastics that including everyday packaging and unsuccessful 3D prints. Then they have cleaned and reprocessed these wastes, embedding local and institutional partnerships into every stage of the design.

Instead of hiding imperfections, the designs highlight them in each detail of furnitures. Transitions of color, imprinted labels, and irregular surface patterns are embraced as defining elements of each chair. The fabrication process combined plastic shredding, pressing sheets, CNC milling, and custom casting, with computational modeling supporting the development of the forms.

Adirondack chair was selected as the central design reference, this situation created both ergonomic and cultural opportunities. The chair, iconic piece of outdoor furniture, typically tied to relaxation and natural settings.

Inside the gallery, the collection is presented as an interactive seating installation, encouraging visitors not only to view but also to sit and engage with the pieces. There are video projections and photography galleries document the circular design process of furnitures including the journey of material collection, preparation, and fabrication, reinforcing. The visualizations in the exhibition reinforce the theme of sustainability as a holistic system rather than a single outcome.

As the curatorial team explains, Plastic Reimagined exhibition began as a classroom exploration into material literacy and circular design, yet its public presentation reveals broader potential. From community fabrication initiatives to reusing local waste streams in everyday environments, the exhibition demonstrates how design education can activate sustainability as a lived practice, supported equally by digital workflows and hands-on experimentation.

Understanding HDPE and PLA in Circular Design

The two materials featured in the exhibition behave very differently, which is part of what makes the project instructive. HDPE, or high-density polyethylene, is the tough plastic found in milk jugs, detergent bottles, and packaging. It can be shredded, melted, and pressed into sheets repeatedly without losing much strength, which makes it well suited to furniture. PLA, or polylactic acid, is a bioplastic commonly used in 3D printing and made from renewable sources such as corn starch. Failed 3D prints are a frequent source of PLA waste in design schools, so reclaiming them for new objects closes a loop that would otherwise end in the bin.

The Fabrication Process Step by Step

Turning loose plastic waste into a usable chair follows a clear sequence. First the collected plastic is sorted and cleaned to remove contaminants. It is then shredded into flakes, which are heated and pressed into flat sheets or melted for casting. Those sheets can be cut and shaped with CNC milling, a computer-controlled cutting process that allows precise, repeatable parts. Custom casting lets designers form thicker or curved components that flat sheets cannot achieve. Computational modelling guides the geometry before any material is committed, reducing waste and helping the team predict how the recycled plastic will perform.

Why Imperfections Become the Aesthetic

A defining choice in this exhibition is to celebrate flaws rather than hide them. Streaks of mixed colour, faint imprints of original product labels, and uneven surface textures all reveal where the material came from. This honesty has a practical benefit too, since recycled plastic rarely produces a uniform colour and trying to mask that often requires extra processing or virgin material. By making the marbled, irregular surface a feature, the designers reduce waste and tell the story of each chair’s origin at the same time. The approach echoes a wider movement in sustainable design that values traceability and material honesty.

Why the Adirondack Chair Was a Smart Reference

Choosing the Adirondack chair as the central form was both practical and symbolic. Its wide, flat slats translate naturally into pressed plastic sheets, making it well matched to the fabrication method. Culturally, the chair is associated with leisure, the outdoors, and durability, which reframes recycled plastic as a desirable material rather than a compromise. Outdoor furniture is also a sensible end use for HDPE because the material resists moisture, rot, and UV better than untreated wood, so the recycled chairs can realistically live outside for years.

Takeaways for Designers and Visitors

Beyond the objects themselves, the exhibition models a repeatable system. Sourcing waste locally, partnering with campus and community recycling, and documenting the full journey from rubbish to finished chair turns a one-off art piece into a teachable workflow. For designers, the lesson is that circular thinking starts with material sourcing and ends with a product that can itself be recycled again. For visitors invited to sit and touch the chairs, the experience makes an abstract idea tangible: waste is not an endpoint but a resource waiting for a new form.
