Bio and neuro inspiration at Metro Vancouver’s (Canada) 2020 Zero Waste Conference (ZWC)

For anyone not familiar with Metro Vancouver (and before I launch into the 2020 Zero Waste conference [ZWC] news and discuss why this year is particularly interesting [to me, anyway]), here’s a description from the Metro Vancouver About Us webpage,

Metro Vancouver is a federation of 21 municipalities [including Vancouver, Canada], one Electoral Area and one Treaty First Nation that collaboratively plans for and delivers regional-scale services. Its core services are drinking water, wastewater treatment and solid waste management. Metro Vancouver also regulates air quality, plans for urban growth, manages a regional parks system and provides affordable housing. The regional district is governed by a Board of Directors of elected officials from each local authority.

2020 Zero Waste Conference (ZWC) celebrates 10 years?

Apparently, the organizers are planning some limited in-person participation for the 2020 edition of the Zero Waste conference (from the Aug. 7, 2020 ZWC blog posting) Note: Pay special attention to the second sentence in the first paragraph,

For the past 10 years, Metro Vancouver’s annual Zero Waste Conference has been at the forefront of Canada’s journey into the circular economy. This year, we are pleased to keep the engagement going online and with an in-person option for a limited number of participants (more to come).

The 2020 Zero Waste Conference promises the same insightful programming we’ve provided over the past decade, but in a new, virtual format. For the first time, conference participants will be able to hear from and connect with the thought leaders, innovators and change agents working to advance waste prevention and the circular economy in Canada – all from the comfort of their own homes or offices.

The COVID-19 pandemic and ongoing public health response may have resulted in some near-term setbacks for the zero waste movement. However, as we work together to ‘Build Back Better,’ it is essential that we critically examine our society’s relationships with products, packaging and waste, and garner the courage to create systems and build infrastructure that will enable a transition to a circular and zero waste economy, creating solutions that combine economic opportunity with benefits to wider society and the environment.

We are living through an era of unprecedented change and transformation. How do we apply our creativity and knowledge to craft a future for Canada that embraces new materials, new ways of doing business and new policies that not only prevent waste and promote circularity, but that help us move toward a more sustainable, healthy and equitable future?

We look forward to highlighting some of the best ideas from the last 10 years and presenting pioneering solutions that take us to a future most of us have only begun to dare dream is possible.

I imagine the option for in-person participation is contingent on the COVID-19 situation in the province of British Columbia and, specifically, the Metro Vancouver region. At the time of this writing, the number of cases in the province are rising steadily, again.

As for the question mark in the head for this subsection, it’s unusual for an organization to not make a big fuss of their 10th annual [anything] leading me to wonder why?

Now, onto the item that sparked my interest in the 2020 ZWC.

Suzanne Lee and growing your clothes

Here’s the August 27, 2020 ZWC notice (received via email) announcing a speaker’s proposed new paradigm for fashion,

Growing a New Paradigm:
Biofabrication Pioneer Suzanne Lee at #ZWC20

The textiles & fashion industry is one of the biggest polluters on earth, accounting for a staggering amount of carbon emissions, water consumption and ocean microplastics.

But what if we could produce durable and beautiful clothes with far less pollution and waste, using the processes at the heart of life itself?

We are pleased to welcome Suzanne Lee, material innovator and founder of Biofabricate, as morning keynote for the “Next Generation Materials” session.

“Biofabrication” uses microscopic organisms to reinvent the way we make everything from clothes to couches to buildings, and holds the promise for radically cutting emissions and eliminating waste.

Join us at the 2020 Zero Waste Conference to hear how Suzanne Lee and her colleagues are using fungi, bacteria, yeast and algae to revolutionize the fashion world from the ground up.

As Suzanne Lee says,

“Once you realize that these materials are better for the planet, animals and us, why would we go back to the toxic, polluting materials of the past?”

Join us on Friday, November 13th for the next phase of Canada’s zero waste journey.

Registration is now open for the 2020 Zero Waste Conference

ZWC 2020 opening keynote address from a ‘neuro guy’

I’ve not come across Dr. Beau Lotto before but according to an August 18, 2020 posting on the ZWC blog, he’s giving the opening keynote address,

Embracing Uncertainty to Spark Innovation – ZWC20 Keynote Beau Lotto

We find ourselves amid uncertain times, and for those of us passionate about systems change and innovation, these are also times of great opportunity. But how exactly do we meet goals like advancing waste prevention and expanding the circular economy in the face of all this uncertainty?

To help answer that question, we’re pleased to introduce you to this year’s Zero Waste Conference opening keynote: Dr. Beau Lotto.

Frontiers in Science of Uncertainty

#ZWC20 Keynote Beau Lotto is no stranger to uncertainty – in fact, that is his main focus as a neuroscientist and entrepreneur.

Through his presentations (including three TED Talks), masterclasses and a proprietary form of consultancy build on “experiential experiments,” Dr. Lotto teaches organizations and individuals how to apply scientific truths about perception to adapt and thrive in an ever-changing world.

His work probes how the human mind deals with the unknown and reveals fascinating and actionable implications for creativity, courage, emotional well-being and social connections.

Unlocking Our Creativity

How do we use the upheaval represented by COVID-19 as an opportunity to build back a more equitable and sustainable future?

The key, as Dr. Lotto said in a recent podcast interview, is to embrace uncertainty:

““Uncertainty is the only place you can go if you’re ever going to see differently the only place you can go if you’re going to be creative.”

As a researcher well versed in the circular economy and the challenges associated with global systems change, Beau Lotto brings a deep understanding of the importance of risk-taking and innovation.

We are pleased to welcome Dr. Lotto to #ZWC20 to set the stage and inspire us to embrace uncertainty and to step forward toward the future we want to bring about.  

How we proceed as a region – indeed, as a province, a country and continent – to address issues affecting our economy, environment and social make-up depends on our collective ability to be creative, innovative, and on our willingness to protect and nurture our communities.

We hope you will join us in the next phase of Canada’s zero waste journey.

Optical fibers made from marine algae

Apparently after you’ve finished imaging with your marine algae-based optical fibers, you can eat them. A July 24, 2020 news item on Nanowerk announces the new research,

An optical fiber made of agar has been produced at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil. This device is edible, biocompatible and biodegradable. It can be used in vivo for body structure imaging, localized light delivery in phototherapy or optogenetics (e.g., stimulating neurons with light to study neural circuits in a living brain), and localized drug delivery.

Another possible application is the detection of microorganisms in specific organs, in which case the probe would be completely absorbed by the body after performing its function.

A July 24, 2020 Fundação de Amparo à Pesquisa dFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) do Estado de São Paulo press release on EurekAlert, which originated the news item, provides a few more details about the researches and the work,

The research project, which was supported by São Paulo Research Foundation – FAPESP, was led by Eric Fujiwara, a professor in UNICAMP’s School of Mechanical Engineering, and Cristiano Cordeiro, a professor in UNICAMP’s Gleb Wataghin Institute of Physics, in collaboration with Hiromasa Oku, a professor at Gunma University in Japan.

An article on the study is published) in Scientific Reports, an online journal owned by Springer Nature.

Agar, also called agar-agar, is a natural gelatin obtained from marine algae. Its composition consists of a mixture of two polysaccharides, agarose and agaropectin. “Our optical fiber is an agar cylinder with an external diameter of 2.5 millimeters [mm] and a regular inner arrangement of six 0.5 mm cylindrical airholes around a solid core. Light is confined owing to the difference between the refraction indices of the agar core and the airholes,” Fujiwara told.

“To produce the fiber, we poured food-grade agar into a mold with six internal rods placed lengthwise around the main axis,” he continued. “The gel distributes itself to fill the available space. After cooling, the rods are removed to form airholes, and the solidified waveguide is released from the mold. The refraction index and geometry of the fiber can be adapted by varying the composition of the agar solution and mold design, respectively.”

The researchers tested the fiber in different media, from air and water to ethanol and acetone, concluding that it is context-sensitive. “The fact that the gel undergoes structural changes in response to variations in temperature, humidity and pH makes the fiber suitable for optical sensing,” Fujiwara said.

Another promising application is its simultaneous use as an optical sensor and a growth medium for microorganisms. “In this case, the waveguide can be designed as a disposable sample unit containing the necessary nutrients. The immobilized cells in the device would be optically sensed, and the signal would be analyzed using a camera or spectrometer,” he said.
