Video: Is Plastic Sustainable? - By The British Plastics Federation
By Shardell Joseph
The British Plastics Federation (BPF) has released two videos to to help tackle some of the public misunderstandings around plastic, addressing its role in society and the best ways to prevent plastic waste.
The video’s were released after an international debate on plastic waste at the World Economic Forum last week, in support of the BPF’s recent document Understanding the Debate about Plastic, which outlines why plastic is important for modern life and the evidence on effective ways to reduce waste.

YouGov findings recently revealed over two-thirds of the public believe that plastic packaging is the most damaging material for producing carbon emissions during its lifecycle. Research into the environmental impact of plastic, however, disproved this, and indicated that that replacing plastic with other materials is not necessarily better for the environment. Academics have also cautioned against swapping plastic for other materials due to the unforeseen negative consequences it may have for the planet.
‘We hope that through widely sharing content such as these videos, we can help clear up public misunderstanding about plastic,’ said British Plastics Federation Director General, Philip Law. ‘The recent YouGov poll results show the issue clearly - most do not appreciate plastic’s role in helping us reduce greenhouse gas emissions.
‘Policymakers and the media need to take note. By turning away from plastics we may do a lot more harm to our environment than good. We must ensure we work together to make the best choices for our planet, and plastic has an important role to play in fighting climate change.’
I just want to yell into the void that I am fucking sick to death of governments promising to do things about climate change by year X. Reducing emissions by year X. Promising to work on it later with no plan and no budget and no fucking commitment.
Enough empty promises! Stop buying time to placate people! ACTION. I WANT ACTION. Put your goddamn money where your mouth is and start implementing clean renewable energy sources! Fine the FUCK out of companies that are killing the planet until they are economically forced to change! I want to see the changes with my own eyes.
Enough of these bullshit lies promising to make changes in ten years, twenty years, thirty years. NOW. Make the changes NOW.
- Broomfield: Question 300 would impose a five-year prohibition on all fracking.
- Fort Collins: Its measure would create a five-year moratorium on fracking and storage of waste products related to the oil and gas industry in town.
- City of Boulder: 2H proposes a five-year moratorium on oil and gas exploration.
- Lafayette: Question No. 300 would ban new oil and gas wells in town. [As well as] prohibit “depositing, storing or transporting within city limits any water, brine, chemical or by-products used in or that result from extraction of oil and gas.”

Brexit, UK-Africa Summit and African Fashion…What’s the Link?
The British people have spoken and a decision has been made on the government and on Brexit. We will leave Europe today, 31st January 2020.
Why am I telling you this?
What does this have to do with your business?
How does this relate to Africa?
Well, let me give you some context.
Early 2020 I attended meetings around the U.K. Africa Investment Summit. I joined as much as I could and was even…
Complicit®
Brent Pruitt, 2021
Each member within society is responsible for the perpetuation of institutional oppression.
To what extent do we, as an individual, or collective, acknowledge our participation? How do we hold ourselves, and each other, accountable?
Complicit® is a declaration of recrimination and confession.
NPR turns 50 this year, so we’re celebrating some of the movies, music and books from the year of our birth, 1971 – like Dr. Seuss’s sadly prophetic The Lorax, which is even more prescient now in the wake of the recent U.N. climate report.
Our own Elizabeth Blair talked to scientists, environmentalists and educators about the book’s legacy – people like Mark Gozonsky, a writer and high school English teacher in Los Angeles whose students have analyzedThe Lorax in the context of global warming. “He kind of says ‘I told you so,’ like, I told you this was going to be bad and now it’s bad,” Gozonsky says. “The book ends on a question mark … 'Well, what are you going to do about it?’ And that’s the very question mark that we land on today.”

The world is spending at least $1.8 trillion every year on subsidies driving the annihilation of wildlife and a rise in global heating, according to a new study, prompting warnings that humanity is financing its own extinction.
From tax breaks for beef production in the Amazon to financial support for unsustainable groundwater pumping in the Middle East, billions of pounds of government spending and other subsidies are harming the environment […]. This government support, equivalent to 2% of global GDP, is directly working against the goals of the Paris agreement and draft targets on reversing biodiversity loss, the research on explicit subsidies found, effectively financing water pollution, land subsidence and deforestation with state money.
The authors, who are leading subsidies experts, say a significant portion of the $1.8tn could be repurposed to support policies that are beneficial for nature and a transition to net zero, amid growing political division about the cost of decarbonising the global economy.
“Nature is declining at an alarming rate, and we have never lived on a planet with so little biodiversity,” [the former head of the UN climate change convention] said. “[…] The report highlights how redirecting, repurposing, or eliminating subsidies could make an important contribution to unlocking the $711 billion required each year to halt and reverse the loss of nature by 2030 as well as the cost of reaching net zero emissions.”

On Earth Day, April 22, Climate Activist Wynn Bruce self-immolated in front of the Supreme Court building in Washington DC.
I saw little coverage in relation to this act. I don’t think it’s right to stifle the selfless action of an individual consumed by concern for the planet; especially as it was his last act on this earth.
I have been working on these pieces since I heard about the incident, and I really didn’t want to release them until I was truly satisfied, as I wanted to do as much justice as possible to the issue.
Art makes ugly issues easier to digest. It can serve as a subtle reminder without forcing the viewer to see the violence of the issue head on.
I hope the message Wynn Bruce was trying to convey spread to the right people. I hope it wasn’t in vain.
Introduction
This latest SCI Energy Group blog introduces the possible avenues of carbon dioxide utilisation, which entails using carbon dioxide to produce economically valuable products through industrial processes. Broadly, utilisation can be categorised into three applications: chemical use, biological use and direct use. For which, examples of each will be highlighted throughout.
Before proceeding to introduce these, we can first consider utilisation in relation to limiting climate change. As has been discussed in previous blogs, the reduction of carbon dioxide emissions is crucial. Therefore, for carbon dioxide utilisation technologies to have a beneficial impact on climate change, several important factors must be considered and addressed.
1)Energy Source: Often these processes are energy intensive. Therefore, this energy must come from renewable resources or technologies.
2)Scale: Utilisation technologies must exhibit large scaling potential to match the limited timeframe for climate action.
3)Permanence: Technologies which provide permanent removal or displacement of CO2 emissions will be most impactful¹.

Chemical Uses
Carbon dioxide, alongside other reactants, can be chemically converted into useful products. Examples of which include urea, methanol, and plastics and polymers. One of the primary uses of urea includes agricultural fertilisers which are pivotal to crop nutrition. Most commonly, methanol is utilised as a chemical feedstock in industrial processes.

One of the key challenges faced with this application of utilisation is the low reactivity of CO2 in its standard conditions. Therefore, to successfully convert it into products of economic value, catalysts are required to significantly lower the molecules activation energy and overall energy consumption of the process. With that being said, it is anticipated that, in future, the chemical conversion of CO2 will have an important role in maintaining a secure supply of fuel and chemical feedstocks such as methanol and methane².
Biological Uses
Carbon dioxide is fundamental to plant growth as it provides a source of required organic compounds. For this reason, it can be utilised in greenhouses to promote carbonic fertilisation. By injecting increased levels of CO2 into the air supplied to greenhouses, the yield of plant growth has been seen to increase. Furthermore, CO2 from the flue gas streams of chemical processes has been recognised, in some studies, to be of a quality suitable for direct injection³.

These principles are applicable to encouraging the growth of microorganisms too. One example being microalgae which boasts several advantageous properties. Microalgae has been recognised for its ability to grow in diverse environments as well as its ability to be cultured in numerous types of bioreactors. Furthermore, its production rate is considerably high meaning a greater demand for CO2 is exhibited than that from normal plants. Micro-algal biomass can be utilised across a range of industries to form a multitude of products. These include bio-oils, fuels, fertilisers, food products, plant feeds and high value chemicals. However, at present, the efficiency of CO2 fixation, in this application, can be as low as 20-50%.

Direct Uses
It is important to note that, at present, there are many mature processes which utilise CO2 directly. Examples of which are shown in the table below.
Summary
Many carbon dioxide utilisation technologies exist, across a broad range of industrial applications. For which, some are well-established, and others are more novel. For such technologies to have a positive impact on climate action, several factors need to be addressed such as their energy source, scaling potential and permanence of removal/ displacement of CO2.
The chemistry of carbon dioxide and its role in decarbonisation is a key topic of interest for SCI Energy Group. In the near future, we will be running a webinar concerned with this. Further details of this will be posted on the SCI website in due course.
