Activated Carbon Market - Forecast(2024 - 2030)

 Activated Carbon Market Overview:

According to the Centers for Disease Control and Prevention (CDC), 780 million people worldwide don’t have access to a clean water source. Furthermore, contaminated water consumption is attributable to the death of 801,000 children under 5 years of age. This is creating a dire need for water purification in which activated carbon is prevalently used as an absorbent. The absorption characteristic of activated carbon makes it useful in a gamut of applications owing to which the activated carbon market witnessed an impressive valuation of $3.560 billion as of 2018, and the demand for the same is poised to escalate at a profitable CAGR of 6.18% during the forecast period 2019-2025.

APAC houses a myriad of industries, especially in the chemical sector, and the water treatment industry is booming in the region due to the regulations enforced by the governments in countries such as China, India, Indonesia, and Malaysia. Furthermore, the rampant construction in APAC is boosting the metal recovery market in the region, which utilizes activated carbon, because it minimizes waste and the usage of chemicals and resins. APAC had the largest activated carbon market share of 40% in 2018.

Activated Carbon Market Growth Drivers:

· The Application of Activated Carbon in Air Purification –

According to the World Health Organization (WHO), 97% cities in the low and middle-income countries with as much as 100,000 residents fail to meet the WHO air-quality criteria, and percentage of the same in developed countries is 49%. This is leading to opportunities in the air purification sector as air purifiers are incorporated with activated carbon which absorbs air-contaminants, thereby improving the quality of air and bringing the content of particulate matter in the air to an acceptable level. The application of activated carbon in air purification is increasing revenues in the activated carbon market.

· The Application of Activated Carbon in Metal Recovery –

Carrboro is a form of activated carbon which is used in the recovery of some precious metals such as silver and gold. When gold is dissolved in the cyanide solution, the solution passes through activated carbon, and the gold is trapped in the micro-pores of activated carbon. Similar process is executed for silver recovery. The application of activate carbon in recovery of precious metals largely supports the activated carbon market.

So NFTgate has now hit tumblr - I made a thread about it on my twitter, but I'll talk a bit more about it here as well in slightly more detail. It'll be a long one, sorry! Using my degree for something here. This is not intended to sway you in one way or the other - merely to inform so you can make your own decision and so that you aware of this because it will happen again, with many other artists you know.

Let's start at the basics: NFT stands for 'non fungible token', which you should read as 'passcode you can't replicate'. These codes are stored in blocks in what is essentially a huge ledger of records, all chained together - a blockchain. Blockchain is encoded in such a way that you can't edit one block without editing the whole chain, meaning that when the data is validated it comes back 'negative' if it has been tampered with. This makes it a really, really safe method of storing data, and managing access to said data. For example, verifying that a bank account belongs to the person that says that is their bank account.

For most people, the association with NFT's is bitcoin and Bored Ape, and that's honestly fair. The way that used to work - and why it was such a scam - is that you essentially purchased a receipt that said you owned digital space - not the digital space itself. That receipt was the NFT. So, in reality, you did not own any goods, that receipt had no legal grounds, and its value was completely made up and not based on anything. On top of that, these NFTs were purchased almost exclusively with cryptocurrency which at the time used a verifiation method called proof of work, which is terrible for the environment because it requires insane amounts of electricity and computing power to verify. The carbon footprint for NFTs and coins at this time was absolutely insane.

In short, Bored Apes were just a huge tech fad with the intention to make a huge profit regardless of the cost, which resulted in the large market crash late last year. NFTs in this form are without value.

However, NFTs are just tech by itself more than they are some company that uses them. NFTs do have real-life, useful applications, particularly in data storage and verification. Research is being done to see if we can use blockchain to safely store patient data, or use it for bank wire transfers of extremely large amounts. That's cool stuff!

So what exactly is Käärijä doing? Kä is not selling NFTs in the traditional way you might have become familiar with. In this use-case, the NFT is in essence a software key that gives you access to a digital space. For the raffle, the NFT was basically your ticket number. This is a very secure way of doing so, assuring individuality, but also that no one can replicate that code and win through a false method. You are paying for a legimate product - the NFT is your access to that product.

What about the environmental impact in this case? We've thankfully made leaps and bounds in advancing the tech to reduce the carbon footprint as well as general mitigations to avoid expanding it over time. One big thing is shifting from proof of work verification to proof of space or proof of stake verifications, both of which require much less power in order to work. It seems that Kollekt is partnered with Polygon, a company that offers blockchain technology with the intention to become climate positive as soon as possible. Numbers on their site are very promising, they appear to be using proof of stake verification, and all-around appear more interested in the tech than the profits it could offer.

But most importantly: Kollekt does not allow for purchases made with cryptocurrency, and that is the real pisser from an environmental perspective. Cryptocurrency purchases require the most active verification across systems in order to go through - this is what bitcoin mining is, essentially. The fact that this website does not use it means good things in terms of carbon footprint.

But why not use something like Patreon? I can't tell you. My guess is that Patreon is a monthly recurring service and they wanted something one-time. Kollekt is based in Helsinki, and word is that Mikke (who is running this) is friends with folks on the team. These are all contributing factors, I would assume, but that's entirely an assumption and you can't take for fact.

Is this a good thing/bad thing? That I also can't tell you - you have to decide that for yourself. It's not a scam, it's not crypto, just a service that sits on the blockchain. But it does have higher carbon output than a lot of other services do, and its exact nature is not publicly disclosed. This isn't intended to sway you to say one or the other, but merely to give you the proper understanding of what NFTs are as a whole and what they are in this particular case so you can make that decision for yourself.

One simple way to look at it is to take the rate of emissions reductions achieved in countries that have successfully decoupled, and see how long it would take for them to fully decarbonize. That’s essentially what Jefim Vogel and Jason Hickel — researchers at the University of Leeds and the Autonomous University of Barcelona, respectively — did in the Lancet Planetary Health study. They found that, if 11 high-income countries continued their achieved rates of emissions reduction, it would take them more than 220 years to cut emissions by 95 percent — far longer than the net-zero-by-2050 timeline called for by climate experts. “The decoupling rates achieved in high-income countries are inadequate for meeting the climate and equity commitments of the Paris Agreement and cannot legitimately be considered green,” the authors wrote. In an interview with Grist, Vogel likened optimism around gradual decoupling to saying, “Don’t worry, we’re slowing down,” while the Titanic races toward an iceberg.

[...]

“Absolute decoupling is not sufficient to avoid consuming the remaining CO2 emission budget under the global warming limit of 1.5 degrees C or 2 degrees C and to avoid climate breakdown,” concluded the Intergovernmental Panel on Climate Change in its most recent assessment. Instead of making growth greener, some economists call for a whole new economic paradigm to address converging social and ecological crises. They call it “post-growth,” referring to a reorientation away from GDP growth and toward other metrics, like human well-being and ecological sustainability. Essentially, they want to prioritize people and the planet and not care so much what the stock market is doing. This would more or less free countries from the decoupling dilemma, since it eliminates the growth imperative altogether. Raworth, the professor at Amsterdam University of Applied Sciences, calls her version of the post-growth agenda “doughnut economics.” In this visual model, the inner ring of the doughnut represents the minimum amount of economic activity needed to satisfy  basic needs like access to food, water, and shelter. The outer ring signifies the upper limits of natural resource use that the Earth can sustain. The goal, she argues, is for economies to exist between the inner and outer rings of the doughnut, maintaining adequate living standards without surpassing planetary limits.  “Our economies need to bring us into the doughnut,” Raworth told Grist. “Whether GDP grows needs to be a secondary concern.”  Vogel and Hickel go a little further. They call for a planned, deliberate reduction of carbon- or energy-intensive production and consumption in high-income countries, a concept known as “degrowth.” The rationale is that much of the energy and resources used in high-income countries goes toward carbon-intensive products that don’t contribute to human welfare, like industrial meat and dairy, fast fashion, weapons, and private jets. Tamping down this “less necessary” consumption could slash greenhouse gas emissions, while lower energy demand could make it more feasible to build and maintain enough energy infrastructure. Some research suggests that reducing energy demand could limit global warming to 1.5 degrees C without relying on unproven technologies to draw carbon out of the atmosphere.

1. The slowest of trailblazers: Better DNA testing means trafficked turtles can go home

““You don't want to just get a turtle and just throw it anywhere,” says Rodrigues, especially because box turtles have a big range, spanning numerous states. So [after they’re confiscated from black market animal traffickers] they wind up stuck in captivity. However, DNA testing has gotten cheap enough and good enough that individual box turtles can finally be traced back to the state where they came from.”

2. New progenitor cell type discovered, may aid in tissue repair and generation

“A team of SAHMRI scientists has discovered a completely new type of cell that […] could be used to boost healing in conditions like diabetes, where the body struggles to repair itself properly. Crucially, these cells don't express typical "self" markers, meaning they could be ideal candidates for stem cell transplantation as they're much less likely to be attacked by the recipient's immune system.”

3. How a Children’s Playground Is Helping With Flood Mitigation

“[This park sits above] a below-ground tank capable of holding hundreds of thousands of gallons of stormwater that city officials say would have otherwise spilled onto the streets or streamed into the basements[….] Others increase resilience with newly planted trees that can absorb carbon dioxide and airborne pollutants; once they mature, those trees also provide shade cover that can reduce the heat island effect of urban areas[….]”

4. Transforming agriculture from carbon source to sink

“The study results indicate that by 2050, these agricultural practices [using cover crops, biochar, and agroforestry] could reduce as much greenhouse gas emissions as planting new forests[….] Carbon sequestration on agricultural land is not only important for climate change mitigation efforts but can also enhance agricultural productivity and resilience to climate change[….]”

5. Rewilding success for long-lost bird population

“Conservation charities have successfully completed the second round of rewilding of a long-lost bird breed in Dover [… after working] over 40 years to restore a suitable grassland for the birds. […] Earlier this year, 108 choughs fledged successfully in Cornwall, according to charity Cornwall Birds.”

6. Over 30 celebrities join auction to put LGBTQ+ books in classrooms

“Pride and Less Prejudice is hosting its fourth annual #BannedTogether virtual auction this weekend with the goal of raising $20,000 to send 1,600 free LGBTQ-inclusive books to elementary schools across the United States.”

7. Advancement of Indian Buffalo Management Act Underscores Bipartisan Support for Tribal-led Buffalo Restoration

“The advancement of [this Act] reaffirms bipartisan support of Tribal sovereignty, self-determination and capacity building for bison restoration on Tribal lands. […] The Indian Buffalo Management Act would secure funding for Tribes and Tribal organizations that have an established buffalo herd and management program, as well as provide resources for Tribes to establish new herds.”

8. Anti-inflammatory drug shows promise in boosting motivation for patients with depression

“Growing evidence suggests one potential cause of low motivation may be persistent inflammation, which suppresses activity within key circuits in the brain. […] Patients who received infliximab demonstrated a greater willingness to exert effort in pursuit of rewards compared to those who received the placebo. […] "By targeting inflammation, we're not only addressing the biological underpinnings of these deficits but also offering new hope for more effective treatment options."”

9. Pig transplant research yields a surprise: Bacon safe for some people allergic to red meat

“Some people who develop a weird and terrifying allergy to red meat after a bite from a lone star tick can still eat pork from a surprising source: Genetically modified pigs created for organ transplant research. […] The company that bred these special pigs shares its small supply, for free, with allergy patients.”

The U.S. Department of Agriculture (USDA) National Institute of Food and Agriculture (NIFA) announced today an investment of $70 million in seven creative and visionary agricultural projects to transform the U.S. food and agricultural system and sustainably increase agricultural production in ways that also reduce its environmental footprint.

This Fiscal Year 2023 investment is part of the Sustainable Agricultural Systems program area of NIFA’s Agriculture and Food Research Initiative, the nation’s leading and largest competitive grants program for agricultural sciences.

The innovative program focuses on a broad range of needed research, education and Extension solutions – from addressing agricultural workforce challenges and promoting land stewardship to addressing climate change impacts in agriculture and filling critical needs in food and nutrition.

“Agriculture is facing a multitude of complex challenges,” said Dr. Chavonda Jacobs-Young, USDA Chief Scientist and Under Secretary for Research, Education and Economics. “We need all hands on deck developing creative, sustainable and strategic ways to feed, clothe and fuel future generations.”

The $10 million awards are for coordinated agricultural projects (CAPs), which are larger-scale and longer-term investments that integrate research, education and Extension efforts. These projects promote collaboration, open communication, information exchange and reduce duplication efforts by coordinating activities among individuals, institutions, states and regions.

“These research investments support exciting projects that integrate innovative systems-based thinking, methods and technologies to establish robust, resilient, and climate-smart food and agricultural systems,” said NIFA Director Dr. Manjit Misra. “These visionary projects will improve the local and regional supply of affordable, safe, nutritious and accessible food and agricultural products, while fostering economic development and rural prosperity in America.”

Explore the seven projects, which include the following:

At the University of Wisconsin-Madison, Dr. Erin Silva is leading a collaboration with the Great Lakes Intertribal Food Coalition, the Wisconsin Tribal Conservation Advisory Council, and the Menominee Nation on a transdisciplinary project that aims to scale up traditional Indigenous food production practices — practices that for generations have already been climate-smart and sustainable — by expanding production, processing, storage, and distribution systems, as well as education and Extension programs, that are needed to support integrated crop-livestock systems, cover crops, and rotationally-grazed cattle and pastured chickens.

At the University of Maine, Dr. Hemant Pendse is leading an integrated research, education and Extension effort to advance the bioeconomy by developing biorefinery technologies that will make the millions of tons of available low-grade woody biomass – which currently has a very limited market – more commercially viable in both the sustainable aviation fuel and fish feed sectors.

At Texas A&M AgriLife Research, Dr. Muthu Bagavathiannan is leading a project that seeks to transform cotton production in the southern United States into a more sustainable, climate-smart enterprise by applying improved precision management practices to increase carbon sequestration and reduce greenhouse gas emissions; enhance pest control, and nutrient and water management; and address labor challenges while creating new market opportunities.

AFRI, which also makes grants in the Foundational and Applied Sciences and Education and Workforce Development program areas, is designed to improve plant and animal production and sustainability, and human and environmental health. Grants are available to eligible colleges, universities, and other research organizations.

the air purifier advice please 🙏

hello!!!!! yes, i will info dump some of the things i come across at work everyday, hopefully it helps!

Quick overview on how air purifiers work: ok so purifiers don't "kill" bacteria/particles which is a lot of the marketing you'll see, air purifiers take in air, filter out particles, and push out clean air back into your home so you don't breathe in the dangerous particles: it's all about airflow (created with a strong motor) and filter type

ONLY trust HEPA and activated carbon filters. every other "technology" out there is not sound, there's no definitive research that proves the effectiveness of any other tech on the market. at best it's ineffective, at worst it's dangerous, i wouldn't trust any of it. some common types of technologies to avoid: ozone generators, ionizers, uv light, when a company has their own "patented tech" that isn't HEPA or carbon

HEPA: this targets airborne particles. dust, pet dander, mold spores, pollen, smoke particles

ACTIVATED CARBON: this targets gasses, volatile organic chemicals (VOCs), odors, smoke odors

Try to find a purifier that's going to cover a lot of your home or at least an entire room - they're portable so I suggest moving them around during the day if you can and bringing them into your bedroom at night.

Finding a purifier that covers your home/room: suggested air changes per hour (ACH) is 4.8 - many companies will list 1 ACH for their square foot coverage to make it seem like it can cover a lot, and it's just not true. Companies SHOULD be sharing their clean air delivery rate (CADR) information that is connected to ENERGY STAR and is tested by the regulatory agency so they cannot fudge their numbers, if they don't share this information it's a red flag

Check CADR and square foot coverage at 4.8 ACH for a product HERE

For example: an air purifier that can clean 1,000 sq ft in 60 minutes with 1 ACH, can clean 500 sq ft in 30 minutes with 2 ACH, and 80 sq ft in 12.5 minutes with 4.8 ACH (it's confusing, i know, but it's important to have a purifier(s) strong enough to clean your indoor space)

Air quality sensors built into purifiers are cheap, i don't trust them to accurately portray your indoor air quality readings, also the apps are...awful: the markets been flooded with smart purifiers it's tough to find one that DOESN'T have an app attached to it. there's nothing wrong with a smart purifier, its up to the user, but its that they can up the price with the add-ons that don't help the main goal of your purifier: clean your indoor air and create healthy indoor air quality in your home

Cross ventilation helps, open those windows!!! air out your home!!! but don't open them on high pollen count or bad air quality days or if you're located near high pollution or close to an active wildfire or smoke. you can check US location air quality HERE ALSO, don't run your air purifiers while you have the windows open. they'll try to clean the outside airflow too, rendering it pretty ineffective.

Look for certifications!!! ENERGY STAR, AHAM, CARB, INTERTEK - these are independent safety and performance certifications that companies have to go through a testing process to receive them, it's not just marketing these are regulations and are standard - if a company doesn't share these results or aren't certified MAJOR red flag

Run those purifiers 24/7!!!!! If they're ENERGY STAR certified (they should be, look for the logo!!) it shouldn't affect your energy bill in a significant way

Just because a purifier costs more doesn't mean it performs better!! just focus on the air cleaning ability: the thing a purifier IS MEANT TO DO: and try to forget about the rest

Unfortunately, a good purifier is always going to be a bit of an investment. the mini purifiers out there and the wearable ones just do not do anything, i wish they did, but filters need surface area to be effective, they're too small, and the motor isn't efficient.

Good news is there should be some very good sales coming up in november!!!! stay safe!!

China’s path to reducing carbon emissions should be determined by China and not controlled by anyone else, President Xi Jinping told dozens of officials, at the same time as US climate envoy John Kerry is in Beijing seeking consensus on global warming.

Xi was speaking at a two-day national conference on ecological and environmental protection that started on Monday, Chinese state broadcaster CCTV reported on Tuesday night.

“China’s commitments are unswerving, but the path towards the goals as well as the manner, pace and intensity of efforts to achieve them should and must be determined by the country itself, rather than swayed by others,” he said.

“[We should] actively and steadily work toward carbon peaking and carbon neutrality, foster a clean, low-carbon, safe and efficient energy system, accelerate the formation of a new power system and strengthen the country’s capability of guaranteeing oil and gas security.”

Xi also urged the country to safeguard ecological security and nuclear and radiation safety to “ensure that the natural environment and conditions, which are the foundation of survival and development, are not threatened or damaged”.

He asked for a concerted legal, market, technological and policy effort to achieve his goals.

The conference was attended by all seven members of the Politburo Standing Committee, the pinnacle of the party’s decision-making apparatus, as well as a wide range of party and government bodies.

Kerry, whose four-day visit concludes on Wednesday, has met Premier Li Qiang and top diplomat Wang Yi, as he seeks consensus on the fight against climate change.

There are also hopes his trip will add positive momentum to US-China relations, in their worst shape in decades.

Kerry tweeted on Tuesday that he appreciated the opportunity to have “an important discussion” with Li on how the US and China can work together to keep the pledge to limit global warming to 1.5 degrees Celsius about pre-industrial levels – a commitment of the 2015 Paris agreement – alive.

Li called for both sides to stick to climate commitments made in the United Nations Framework Convention on Climate Change and the Paris Agreement.

Xi promised in September 2020 that China’s carbon emissions would peak by 2030 and become carbon neutral by 2060. In 2021, he said China would tightly control coal consumption and gradually reduce it after 2025.

China has repeatedly emphasised the need to secure its energy security and deliver on its climate commitments.

The most recent government work report to address the issue – submitted to the National People’s Congress, China’s legislature, in March by the previous premier Li Keqiang – said research and development of clean energy was a priority for 2023.

In April, the National Energy Administration announced plans to add 160 million kilowatts of installed wind and solar capacity by the end of this year, boosting the share of wind and solar electricity to 15.3 per cent of society’s energy use.

“Three years after making its carbon-reduction pledge, China’s energy and industrial transitions are still far from complete,” said Ma Jun, director of the Institute for Public and Environmental Affairs, a non-profit environmental research firm.

While China’s renewable energy is increasing, China has approved more coal projects recently, noted Ma. “Due to complex geopolitical changes, China has shifted its focus to energy security,” he said.

A major stumbling block to an agreement between the US and China on climate issues is China’s use of coal power. Washington wants China to reduce its domestic reliance on coal to cut more methane emissions. But Xi has reiterated many times that it is a matter of “energy security”.

There has been a significant increase in approvals for coal power projects within China since last summer’s extreme heatwave, which led to power supply crunches in several southern provinces. The rise in domestic approvals has sparked international concern about China’s ability to deliver on its climate promise.

On Kerry’s last visit to China in August 2021, he asked Beijing to stop funding coal power projects outside its borders. A month later, at the UN General Assembly, Xi announced that China would no longer build new coal power overseas.

Regarding China and US’s differences in climate issues and carbon reduction, Ma said, “What we have to see is what kind of cooperation the two sides are going to go for, and whether they can achieve a win-win situation on what each side is good at.”

Hybrid aspen bark as a raw material for new product applications

The extractives and chemical composition of hybrid aspen bark allow it to be used in several applications in the chemical industry. In the doctoral dissertation of Pasi Korkalo, who is a researcher at the Natural Resources Institute Finland (Luke) and a doctoral student at the University of Oulu's Sustainable Chemistry unit, the chemical composition of the bark biomass of hybrid aspen was studied, activated carbon was produced from the bark extract, and a pesticide chemical was produced from the bark's hemicellulose. All chemical products were separated from the biomass following cascade processing principles.

The hybrid aspen tree, a species that originated from the crossbreeding of European and American aspen, was introduced to Finland in the 1950s. Its fast growth made it an attractive raw material for the wood industry. However, the hybrid aspen did not reach the same value as other dominant tree species in the market, as the market changed significantly before the cultivated hybrid aspen plantations were ready for harvesting.

"Currently, hybrid aspen is seen as an opportunity to increase diversity in conifer-dominated forests. Applied chemistry can explore new uses and added value of the trees," says Pasi Korkalo.
