Enzyme is the Answer to Plastics Filling Up Landfills

0

Chattanooga had as one of its largest employers the DuPont Company which produced polyethylene terephthalate, or polyester fibers for everything from women’s hosiery to tires. Today, those plastics are filling up more than just our pantries, closets, and homes with products that end up in landfills that take up to 500 years to breakdown and decompose.

The same science that assisted in creating the advancement of this universally used plastic has now helped solve the growing problem. No. Trash, waste management, and the issue of refuse is not front of mind but knowing that microplastics do end up in our water, kill wildlife, and change our environment should make all of us more aware of how we consume and dispose of those products.

Researchers at the University of Texas in Austin (UTA), or as Tennessee folks say, “The other UT,” have worked on and employed an enzyme called FAST-PETase which is used to turn these used, dirty, and damaged plastics into reusable materials.

As the hope is to achieve a more “circular economy” in the area of consumables, researchers aim to take that which is produced, used, then discarded as spent or no longer needed to remain in that loop of materials to be reused over and again without every leaving the closed system of manufacturing. This approach would obviously protect our landfills from overuse and unnecessary expansion, but also other environmental benefits such as water and air quality and the accomplishment of being good stewards of that which is manufactured and consumed.

FAST-PETase is a variant of an enzyme created at UTA by a collaborative team of engineers and scientists that works by attacking the molecular structure of polyethylene terephthalate (PET), found in bottled water, soft drinks, food wrappers, and textiles. It’s estimated that this type of plastic makes up at least 12% of all waste–all, throughout the entire globe.

Through synthetic biology, the specific enzyme, or protein works to depolymerize plastics at low temperatures and lives up to its name: functional, active, stable and tolerant. This FAST-PETase will eliminate billions of tons of waste that takes centuries to decompose.

The obvious application of this creation of wonderful minds working with computer analysis is within recycling and this circular economy of things.

Another key application is in remediation. There are many lands and spaces made unusable by our approach to life, which is to be mobile, use excessive amounts of disposable bottles and containers, and assume there won’t be any consequence. Stay tuned for FAST-PETase and its application in years ahead. No, this does not mean our wasteful and careless habits are justified. The advancement, instead, assists us as good stewards to correct mistakes and current messes we’ve made, and work toward better communities that are sustainable as Hamilton County and Chattanooga work to deal with the Summit and Birchwood landfills.

Special Report – Part 3 – Extreme Risk Protection Orders Examined

Tennesseans understand there will be a legislative session called by Governor Bill Lee as announced on May 8 to discuss and debate school safety, preventing firearms from getting into the hands of individuals who have been deemed a harm to themselves or others, and the fact that the United States Constitution–the Law of the Land–protects the right of a law-abiding citizen to own, posses, and use a firearm for personal protection.

Before going further, appreciate that this will prove to be a tedious task. Every person brings to any situation their own experiences, opinions, and desires as facts are debated. That simply means something as simple, as some might argue, as keeping firearms out of the hands of the mentally ill or any who are deemed a threat safety is not so simple.

This is all demonstrated by the parable of the blind men asked to describe an elephant through their sense of touch, which they have never seen to know its image. One touches the large beast’s side and declares it to be as a large wall; another examines through touch the pachyderm’s tusk and pronounces it to be as a spear; another is only able to touch the elephant’s trunk and declares it to be snakelike.

You get the idea.

The same will be at play on August 21, as the special session of the Tennessee General Assembly commences this time of deliberations, as described by Governor Bill Lee, “to continue our important discussion about solutions to keep Tennessee communities safe and preserve the constitutional rights of law-abiding citizens.”

At the center of the debate will be extreme risk orders. The Governor and Representatives Sam Whitson (R) and Darren Jernigan (D) have all three made public statements to support this process currently used in Tennessee in the area of domestic violence to protect victims of harassment and violence from escalation and future harm.

What’s the big debate over an extreme risk protection order since it’s not a crime, but employs law enforcement, medical professionals, and the court to remove weapons from those alleged to demonstrate dangerous behavior?

While the accusation made toward a respondent is not a crime, he or she will have a court record and a medical record based on a complainant. This accusation may or may not be substantiated with a fact pattern or evidence of behavior, as demonstrated by the broad scope of other states which have similar laws in place. Upon the actions of law enforcement, medical professionals, and the court, a constitutional right may be taken from a citizen based on the belief or accusation, not a crime committed.

However, in many cases, there may, indeed be evidence, behavior, or even a history and is an appropriate behavior-oriented intervention. Yet, the precedent set by taking a right from one prior to a crime is unconstitutional.

 The dilemma relates to the parable. Let’s just hope Tennessee leaders debate, discuss, and decide with their eyes open and avoid using only their feelings.

Supreme Court Justice Clarence Thomas seeks to reverse the legacy of his predecessor, Thurgood Marshall

FedEx Professor of Law; Author of The Transition: Interpreting Justice from Thurgood Marshall to Clarence Thomas, University of Memphis

The CONVERSATION- As public attention focuses on Supreme Court Justice Clarence Thomas’ close personal and financial relationship with a politically active conservative billionaire, the scrutiny is overlooking a key role Thomas has played for nearly three decades on the nation’s highest court.

Thurgood Marshall, had a very different view of the purpose of the Supreme Court than his successor, Clarence Thomas (pictured).

Thomas’ predecessor on the court, Thurgood Marshall, was a civil rights lawyer before becoming a justice. In 1991, in his final opinion before retiring after a quarter century on the court, Marshall warned that his fellow justices’ growing appetite to revisit – and reverse – prior decisions would ultimately “squander the authority and legitimacy of this Court as a protector of the powerless.”

His prediction has been quoted by Supreme Court decisions since, including a three-justice dissent from the June 2022 Dobbs v. Jackson Women’s Health Organization ruling that declared there was no constitutional right to reproductive choice and overturned Roe v. Wade.

In his concurrence with the majority decision in that case, Thomas declared his opposition to Marshall’s principle, lamenting that the court had not done more to pare back its prior work. “In future cases, we should reconsider all of this Court’s substantive due process precedents,” Thomas wrote – directly implicating Americans’ rights to sexual privacy and same-sex marriage.

Throughout Thomas’ tenure he has pushed the Supreme Court to revisit prior decisions that embraced robust rights for society’s most vulnerable, and to replace Marshall’s vision with one more amenable to the powerful than the powerless. And in writing my book tracing the lives and work of both justices, I have seen the fruits of this effort multiply over the past decade.

A shield for those in need

Few phrases could so aptly capture Thurgood Marshall’s vision of the court’s work as “protector of the powerless.” And few, if any, Americans have done as much to make that vision a reality.

Marshall’s work to advance Black citizenship is well known, but he also fought for expanded rights for women and the indigent, the accused and convicted, adherents to marginalized religions and those with unpopular viewpoints.

At the root of Marshall’s jurisprudence was a hope that while law could be a powerful tool of oppression, it might also be a shield.

As he wrote in that final dissent, in Payne v. Tennessee, enforcement of constitutional rights “frequently requires this Court to rein in the forces of democratic politics,” to protect the powerless from the tyranny of the majority.

While his Payne dissent criticized the court for reversing itself, Marshall was no stranger to calling for reconsideration of established law. Marshall’s signature accomplishment as a lawyer in Brown v. Board of Education was to convince the court to overturn the doctrine of separate but equal that had emerged after the 1896 Plessy v. Ferguson decision.

As a justice, Marshall argued passionately and repeatedly that the death penalty violated the Eighth Amendment’s prohibition on cruel and unusual punishment, leading to a brief period where it was considered unconstitutional.

The distinction between Marshall and Thomas is not really about whether the court should reverse past decisions but simply which ones.

While Marshall willed the court to become a “protector of the powerless,” Thomas has, I believe, argued not only to scale that vision back, but to advance the interests of the powerful.

Power as a key factor

While last summer’s abortion decision is an obvious example, Thomas has led the court’s assault on precedent in other areas as well.

For example, years before the court invalidated portions of the Voting Rights Act in Shelby County v. Holder, Thomas had argued that the lack of modern voting discrimination made the act unnecessary.

Similarly, recent decisions have followed Thomas’ lead in weakening the vitality of the First Amendment’s Establishment Clause, which fortifies the separation between church and state.

Thomas has even called for the court to reconsider its ruling in Gideon v. Wainwright, which established a constitutional right to a lawyer for indigent criminal defendants.

In each case, it is the powerless who stand to be most significantly affected.

Those in need of constitutional protection in Thomas’ view are more likely to be property owners, corporations making campaign contributions or gun owners.

On affirmative action

Perhaps no topic better captures the distinction between the two men’s views than affirmative action, which the court is considering in a pair of cases from Harvard and the University of North Carolina to be decided this term.

The distrust of government that fuels many of Thomas’ perspectives is never more personal than in cases about the use of race in college admissions. He has railed against affirmative action, saying it brands Black people in prominent positions with a “stigma” about “whether their skin color played a part in their advancement.”

Indeed, Thomas claims his position requiring colorblindness is a better path toward full Black citizenship. He has made that claim even in situations where he knew it would result in more limited access to opportunities for Black students in the short term.

Marshall always looked at the issue from a different perspective, arguing that access to opportunities was essential not only for the Black students affected but for the nation at large.

“If we are ever to become a fully integrated society, one in which the color of a person’s skin will not determine the opportunities available to him or her,” Marshall wrote in 1977, “we must be willing to take steps to open those doors.”

It was access for the powerless that Marshall thought ought drive the thinking of the court.

But this summer, the court may finally embrace a different vision on affirmative action, coming again to a position Thomas has been advocating for decades. That turn would be yet another reversal squandering Marshall’s vision of the court. (The CONVERSATION)

They all ‘look alike’ to me!

I left the store and headed to my bright red car. About ten feet away, I tapped the silver button on my key fob to open the door. Humm, it didn’t open.  

So, I put my bag on the ground and pushed the key into the door to open it manually. Again, nothing.

Befuddled, when I looked away thinking about my options, (AAA, calling wife) I noticed a red car, same color as mine, parked next to me.

Uh, oh!

I turned back and peered into the window of the car I couldn’t open and, oh shucks, its contents indicated that it was not my car. Shocked by what just happened – or could have happened – I unlocked and retreated to my car, climbed into the front seat, wiped away the sweat and tried to process what just happened…. and, considering the world we live in today, the tragic consequences of what could have happened.

As I sat there breathing heavily, images in my mind of friends and loved ones parading past my open coffin, the result of what could have happened, was unnerving. I snapped out of that daymare and got the heck out of that parking lot.

Let’s look at my experience against news that took place over a recent span of six days.

First, when Ralph Yarl rang the doorbell of Andrew Lester’s Kansas City, Mo., home by mistake, the 84-year-old White man was “scared to death,” he told police. No words were exchanged, Lester told police, before he lifted his .32-caliber revolver and shot through a glass door at Yarl, hitting him in the head and arm. Although Yarl, who is 5-foot-8 and 140 pounds, Lester said the teenager was a “Black male approximately 6 feet tall,” and that he was scared to death due to the male’s size. Two days later in upstate New York, a group of friends pulled into the wrong driveway. The homeowner came out and shot at them killing one, a 20-year-old girl.

Three days later a cheerleader in Texas got into the wrong car and got out, but the man in the car got out and shot her. Soon after, a Walgreens employee opened fire in the parking lot on two women suspected of shoplifting. And when a little girl’s basketball in North Carolina ended up in a neighbor’s yard, that neighbor came out and shot both her and her father.

Now what’s petrifying about all this is the unsettling reality that by the time the ink is dry on this piece, more similar shootings will happen. So the question we’re left with – Black parents in particular – how do you hold back the outrage and tell your Black kid what they must do just to survive in public these days?

Now does a lot of this have to do with race? Of course it does. In all cases, no. In far too many cases, emphatically yes. There’s no denying that a person’s physical characteristics, skin color chief among them, are often the cause of “scared to death” knee jerk reactions.

Research confirms, for example, that people who were asked to judge the size of Black people tended to see Black men as bigger and stronger than they actually were and gave Black children the attributes of adults. Need evidence? Well look no further than some recent high profiles that garnered headlines.

When a police officer shot 12-year-old Tamir Rice in 2014, the president of the Cleveland Police Patrolmen’s Association defended the officer describing Rice as “a 12-year-old in an adult body.” And former Ferguson, Mo., police officer Darren Wilson, who fatally shot 18-year-old Michael Brown in 2014, likened the struggle inside his vehicle that preceded the deadly shooting to “a 5-year-old holding onto Hulk Hogan.” Need I go on?

Back to the shooting in Kansas City, that city’s African American mayor, Quinton Lucas, said that since Yarl’s shooting, he’s questioned whether he would be in danger if he rang the doorbell at the wrong home at night. This, mind you, from the mouth of the mayor of a city with a population of a half million people.

“Before last Thursday, I don’t know if there’s a parent in America who would advise their child, White or Black, not to ring the doorbell,” Lucas said. “People need to reassess their biases and fears and recognize that Black people are not villains, that Black kids are not a threat,” he said. “There was no reason to fear this boy.”

Now this – brace yourself – said by Lester’s neighbors, the ones who refused to open their homes to a severely wounded Ralph Yarl, about Lester:

“He is a kind veteran.” 

 “Race did not play a part in this.”  

“He was just scared.”

So, where do we go from here America?

On my side of the answer, I plan to heed the advice from several Black parents:

Said one, never do a U turn into an unfamiliar driveway. Rather, drive to the nearest parking lot even if that means taking more time to course correct.

Said another, let young ones, boys in particular, know that the way they dress, and their voice tones can evoke strong negative reactions as do braids, tattoos, dreadlocks, and even facial expressions.

Said another, instruct them to use their GPS in advance to familiarize themselves with the picture of the place they’re going to and call the place in advance to confirm the address.

Back to my red car dilemma, perhaps I luckily “dodged a bullet” (pun intended) and should be grateful that some panicky “Lester” did not see me, five feet, ten inches tall and 185-pound soaking wet, as a hulking 6-foot 5-inch, 250-pound Black dude bent on emptying his wallet, stealing his Bud-Lite, or administering him some serious body damage.

For heaven’s sake America, the home of the free and land of the brave, who would have thought that a human mistake nowadays could earn you a trip to the local morgue! © Terry Howard is an award-winning speaker, writer, and storyteller.

Special Report – Part 1: Action After the Nashville School Shooting – What’s Next

Tennessee State government will be funding school resource officers, mental health resources within schools, as well as improvements to school facilities’ security after the Nashville shooting in a private Christian school on March 27.

Governor Bill Lee confirmed plans to call the General Assembly back into a special session to discuss and debate some type of legislation addressing the access of weapons by individuals who are a harm to themselves and to others. Speculation as to this special legislative session points to a time after July, possibly as late as September.

Some demand immediate action that would limit gun ownership, limit the types of weapons sold and owned, as well as outlaw large capacity weapons and clips completely. Conversely, others believe their right to own weapons under the protections of the US Constitution’s Second Amendment transcend all other scenarios, rejecting measures that would limit sales, ownership, or manufacture.

Governor Lee, a Republican with a record of support of the Second Amendment, signed an Executive Order on April 11 which strengthened the background checks of individuals purchasing weapons through use of the Tennessee Instant Check System to both report relevant information and permit gun purchases.

Tennessee’s fiftieth governor also challenged Legislators to pass an order of protection proposal that would use the existing framework currently protecting victims of domestic abuse and violence from the perpetrators of their harm.

Present Tennessee law utilizes a process for victims seeking protections from an abuser involving law enforcement and the judicial system that includes a provision, among other interventions, whereby the Court orders the perpetrator to surrender all firearms. This dispossession of firearms means the named respondent/defender is “prohibited from possessing a firearm for so long as the order of protection or any successive order of protection is in effect.”

Governor Lee suggests this same approach be used for a temporary dispossession of firearms for a period not to exceed 180 days following a court petition by law enforcement regarding an individual believed to be a harm to themselves or others.

Terminology commonly used to debate legislative intervention, in addition to “orders of protection,” includes “red flag laws” or “extreme risk orders.” Nineteen states and the District of Columbia have some type of extreme risk or red flag laws in place. Virginia is the only contiguous state to Tennessee with such laws, with Florida’s Extreme Risk Law in force since passage in March 2018.

In Tennessee, the last legislation to address weapons possessed by those deemed a harm to themselves or others was passed in 2019 after the Nashville Waffle House shooting where the shooter’s father returned a high-powered weapon to the disturbed man despite his known history. The law, signed by Governor Bill Lee on May 21, 2019, made it illegal to transfer a firearm to a person known to have been deemed a substantial or serious harm due to mental illness or emotional disturbance by a physician and adjudicated through the Court.

2023 Chattanooga Armed Forces Day Parade

Lt. Col. Bill Brooks, USA [Ret], Chairman of the Chattanooga Armed Forces Day Parade Committee, announced today that General Duke Z. Richardson, USAF, will serve as the Chief Military Reviewing Officer and will address the Armed Forces Day Luncheon, both on Friday, May 5, 2023.

General Richardson serves as Commander, Air Force Materiel Command, headquartered at Wright-Patterson Air Force Base, Ohio. He is responsible for installation and mission support, discovery and development, test and evaluation, life cycle management services, and sustainment of virtually every Air Force weapon system. The command employs 89,000 people and manages $72 billion of budget authority annually.

General Richardson enlisted in the Air Force in 1983 as an avionics technician, later received his commission via Officer Training School, rising through the ranks to his current position as General, USAF.

Bo Cline, US Army Air Corps, World War II, Former POW, Parade Grand Marshall

Cline earned the rank of 2nd lieutenant while he as a bombardier navigator in the 391st bomb group 574 squad, 9th Air Force, USA. During the battle of the Budge, Cline۪’s plane was shot down during a bombing mission intended to hit the German village of Ahrweiler. When he made it to the ground, he was captured by German soldiers and spent the next 8 months in a German POW camp until the camp was freed by the Soviet Army.

As a POW he was put in a barrack – a shed, really – with 23 other prisoners. They ate small daily portions of bread, cut to the millimeter to ensure equal portions, and then they toasted the crust to make a delicacy they called “kriegy nuts” – from “krieg,” the German word for war.

After being liberated by advancing Russian troops, Cline returned to the United States, went to college with the help of the GI Bill, and eventually settled in Chattanooga, where he spent 30 years working for the former Provident Life and Accident Insurance Co., now Unum, before retiring in his early 60s. Mr. Cline and his wife are dedicated members of their church and Cline is an active member of MOAA and other veteran groups.
