Roots to Renders - Sugarcane's Journey into Creative Design

"A world where materials are in harmony with nature." Wouldn’t that be amazing? I truly believe, that biophilic designers can specify this change, and also help scale innovation to make this happen.

The global plastics crisis is stark: over 400 million tonnes of plastic are produced annually, with a staggering 99% being fossil-based and 91% never recycled. The plastics industry contributes 3.4% of global greenhouse gas emissions, equivalent to 1.8 billion tonnes of emissions. Hao Ding, Global Marketing Director at TotalEnergies Corbion, unveils the potential of Polylactic Acid (PLA) - a bio-based material that could help how architects and designers approach sustainability. According to a new Life Cycle Assessment, PLA reduces carbon footprints up to 85% compared to conventional plastics.

PLA stands for Poly Lactic Acid, a bio-based plastic material made from renewable resources like sugarcane or corn. Specifically, as Hao explained in the interview, it's produced through a process of fermenting plant sugars to create lactic acid, which is then polymerised into a plastic-like material. Unlike traditional petroleum-based plastics, PLA is:

- Made from renewable resources
- Biodegradable
- Reduces carbon footprint by up to 75%
- Food contact approved
- Usable in multiple applications like packaging, 3D printing, textiles, and medical packaging

A key difference is that PLA starts from plants that absorb CO2 during growth, whereas conventional plastics are derived from oil pumped from underground. When composted, PLA breaks down completely without leaving persistent microplastics, making it an environmentally friendly alternative to traditional plastics. PLA can reduce carbon emissions by up to 75% compared to conventional plastics. "PLA can replace most conventional plastics and offer similar performance."

Architects and designers can leverage PLA in multiple applications.

Design and Construction Applications:
1. Furniture packaging materials
2. Exhibition and conference temporary structures
3. 3D printed decorative objects
4. Cavity wall insulation
5. Prototype and model making
6. Textile and upholstery applications

Reconnecting with nature will save our society

Sustainability matters, it is a matter of survival. For Carlo Battisti, President at Living Future Europe this is essential. We cannot design or build without considering this.

We already know the solutions, we need to implement them.

Carlo co-founded the Biophilic Society and coordinates LFE biophilic design strategy. “There are so many global issues to solve, our responsibility must start from the built environment, we know that 40% of emissions come from built environment and these have an impact on global issues.”

Each time we build, we start from scratch which means it’s difficult to standardise the processes, also the sector is so slow to change, but the built environment shapes the way we are living.

Carlo tells us about his experience and also about the Living Building challenge framework which was developed in 2006. We are now at the 4th version of the standard which was published in 2019. Biophilic Design has always been a core part of this framework. If we design and build with a better connection to nature, using natural light, better airflow, etc, there will be better energy consumption, greater energy efficiency. Also of course, there are lots of studies which show that bringing sufficient daylight into enclosed spaces, for instance in schools or hospitals, patients recover quicker, students learn faster in classrooms. There is such interesting and robust data.

The Biophilic Summit is taking place on 7th June 2023. The details of the summit programme and how to register can be found here: https://lfeurope.regfox.com/biophilia-summit-2023
