The shock of an alarming release of the report at the Climate Change conference in Madrid COPs 25 yesterday on the
discovery loss of widespread ocean oxygen is another watershed moment that must be recognised as dire for our future
“Oceans losing oxygen at unprecedented rate, experts warn of the loss of ocean oxygen at-unprecedented-rate”
“Oxygen in the oceans is being lost at an unprecedented rate, with “dead zones” proliferating and hundreds more areas
showing oxygen dangerously depleted, as a result of the climate emergency and intensive farming, experts have warned.
Sharks, tuna, marlin and other large fish species were at particular risk, scientists said, with many vital ecosystems
in danger of collapse. Dead zones – where oxygen is effectively absent – have quadrupled in extent in the last
half-century, and there are also at least 700 areas where oxygen is at dangerously low levels, up from 45 when research
was undertaken in the 1960s.”

University of Ottawa already has a study about this issue in a discussion you tube presentation. https://www.youtube.com/watch?v=j4ynqsRQcoM
Paul Beckworth states; “Combustion of fossil fuels causes oxygen to decrease in the atmosphere/ocean system.
As does deforestation, exponential population growth and phytoplankton loss in the oceans from warming stratification
limiting nutrients at the surface.
It is often said that the oxygen in every second breath you take is produced by photo plankton, that are the true lungs
of the planet. I discuss the extend of the oxygen decrease, which is more than you want to know.”
We know already that micro-plastics are detected in our oceans and even deposited in ice packs and alpine snow in many
areas of the globe now.
So where could some of the “micro-plastics” come from?
Now a German scientific study has traced the micro-plastics to tyre ‘particulates’ from vehicles, so we are now part of
the problem apparently.
Tyres are used in every corner of the globe now, and we have never considered tyre dust to be a threat and a potential
pollutant to our environment, have we?
Tyres are made from oil ‘distillate’ products like styrene ,polyethene, nylon, butadiene and many others including
formaldehyde, - so we should not be surprised at the sheer problems these “micro-plastics may be causing to our
environment now and all living organisms.
So could we find ‘cleaner less toxic materials’ from which to make those tyres from?
We studied this problem and discovered that in 2001 three large international tyre companies came together to fund a
study to produce a ‘prototype tyre’ that contained far less toxic chemicals than tyres are currently made from, which
consisted of wood, grass and corn derivatives which may be a part solution to our reduction and less use toxic petroleum
waste products and those companies are Bridgestone, Michelin, and Yulex Corporation specifically.

On the product application font, Bridgestone has recently launched Ecopia EP001S tyre with an A/A rating for wet grip as
well as fuel economy in Europe and Japan.
Optimized top tread compound with maximum resistance toward aquaplaning and increased stiffness of the tread blocks has
led to such improved tyre performance.
In 2012, Michelin had launched the MICHELIN ENERGY EV tyre for electric cars to increase their autonomy, which improves
fuel economy and hence contributes toward sustainability.
Bridgestone has very recently developed tyre, which is made of 100% Guayule rubber. The company has also set an
ambitious target of producing its entire tyre portfolio from sustainable materials.
Recently, Yulex Corporation has launched Yulex Pure, a guayule rubber that meets the requisite critical performance
standards for many medical, industrial, and consumer applications and surpasses the performance standards of many
The company is using advanced genomic technologies for commercial production. These are a few instances, which reflect
the urge and motivation of various companies toward sustainability.
Perhaps now NZ could become a world leader by finally producing the first ‘new commercially available ‘eco-friendly
vehicle tyre composition’ since it has been science tested but yet to go into production here?
‘Eco-friendly vehicle tyre composition’ has been on the scientific horizon and has been known since 2001, - so why is it
not in widespread use by now?
Perhaps ‘Big Oil’ felt it would damage their financial status after an oil free component vehicle tyre may be popular as
they can be made of grass, trees, corn, and perhaps no petrochemicals may be needed to build the first “Eco-tyre?
(QUOTE) “According to the Rubber Manufacturers Association, each tire produced takes 7 gallons of oil”
These two documents provide the evidence to show about “road dust from tyres is an overlooked pollutant of our
Tyre dust is micro-plastics.
• If the world is to limit the effects of global warming, drastic changes must be made and the Intergovernmental Panel
on Climate Change (IPCC) report https://www.ipcc.ch/sr15/
• All must be taken seriously now along with; “Comparison of Tire and Road Wear Particle Concentrations in Sediment for Watersheds in France, Japan, and the United
States by Quantitative Pyrolysis GC/MS Analysis” report on sediments for watersheds.
QUOTE: “Comparison of Tire and Road Wear Particle Concentrations in Sediment for Watersheds in France, Japan, and the United
States by Quantitative Pyrolysis GC/MS Analysis
Impacts of surface runoff to aquatic species are an ongoing area of concern. Tire and road wear particles (TRWP) are a
constituent of runoff, and determining accurate TRWP concentrations in sediment is necessary in order to evaluate the
likelihood that these particles present a risk to the aquatic environment. TRWP consist of approximately equal mass
fractions of tire tread rubber and road surface mineral encrustations. Sampling was completed in the Seine (France),
Chesapeake (U.S.), and Yodo-Lake Biwa (Japan) watersheds to quantify TRWP in the surficial sediment of watersheds
characterized by a wide diversity of population densities and land uses. By using a novel quantitative pyrolysis-GC/MS
analysis for rubber polymer, we detected TRWP in 97% of the 149 sediment samples collected.
When we looked into the humble household carpet for any emissions of “micro- plastic particulates we were again shocked
that 95% of the standard carpeting today is made from oil based derivatives again such as ‘Nylon 6’ and it’s many
volatile organic chemical components. https://circulareconomy.europa.eu/platform/sites/default/files/knowledge_-_toxics_in_carpets_eu_review_anthesis_final_study.pdf
What Toxic Substances are Present in Carpets according to the EU.
Nonylphenol Ethoxylates (NPEOs
Stain Repellents: Per- and polyfluorinated alkyl substances (PFAS
Heavy Metals & Metal Compounds
Dyes and Pigments.
Polycyclic Aromatic Hydrocarbons (PAHs)
Other VOCs – “New Carpet Smell”.
Polyvinyl Chloride (PVC).
Styrene Butadiene Rubber Latex (SBR Latex)
This potentially toxic combination used in carpeting was only produced since woollen carpeting was less aggressively
marketed as a floor covering for insulation during the 1970’s although the performance of insulation using wool was
three times more thermally efficient than ‘Nylon 6’ plastic acrylic carpeting insulation is.
Now any nylon carpeting dust is linked to many health concerns, and is regarded as a human toxic exposure if the dust
particles and VOC gasses released are breathed into the lungs and consumed in food consumed. The nylon dust from walking
and wear will become a ‘micro-plastic’ when we are walking outside and removed from our shoes then washed down drains by
rain. Did we ever think of this?
Then we have now according to this UN press release below;
Wednesday, 4 December 2019, 9:34 am
“Exceptional global heat driven by greenhouse gas emissions mean this decade will most likely go down as the warmest on
record, according to the World Meteorological Organization (WMO
) which released its provisional statement on the State of the Global Climate
So if our every day use of plastics in ‘every walk of life’ is not checked for ‘micro-plastics’ then we are part of
today’s problems that are causing climate change.
Big question is; - ‘How to firstly stop destructive loss of ocean oxygen’?
We have always advocated to Government for our transport to return using rail as our prime mover ‘of people and freight’
around our country.
With rail we have no transport tyre ‘micro-plastic’ emissions, as micro-plastics are seen as the worst enemy causing
climate change in the articles above.
So less ‘transport micro-plastic dust’ is considered as a major plus - and only ‘steel wheels on a steel track’ will do
the job to deal with Climate change, so if we lower the micro-plastics emissions in our environment we will make our
lives healthy again then.
