B.C. scientists and First Nation create decomposing ‘biofoam’ packaging from wood

Published

VANCOUVER — Styrofoam can take 500 years to decompose as it bloats landfills around the world, but new packing material called biofoam made of forestry waste can decompose in a matter of weeks, say scientists.

University of British Columbia researcher Feng Jiang says that’s a potential environmental boon, because Styrofoam currently fills up to 30 per cent of landfills.

“So, we have been doing a few tests, which is putting biofoam into the soil and then it started degrading … and after two months, it will be completely gone,” said Jiang, an assistant professor in the university’s faculty of forestry and the Canada Research Chair in sustainable functional biomaterials.

The biofoam project is a collaboration between the Wet’suwet’en First Nation in central B.C. and University of B.C. researchers.

The partnership came about three years ago when Jiang met Reg Ogen, president and CEO of the First Nation’s Yinka Dene Economic Development Limited Partnership, at an encounter arranged by the B.C. Forests Ministry.

Jiang and his fellow scientists listened as First Nation members described concerns about what to do with wood waste on their land.

Ogen said wildfires and infestations of mountain pine beetles in the 1990s and 2000s had created large amounts of waste that they wanted to be used in a meaningful way.

“We met with Dr. Jiang there and we looked at different ways of utilizing the wood waste and finally we came up with a product that I think we can do something good with. And hopefully, at the end of the day, to keep all of the Styrofoam out of the landfills and then make sure that we continue to protect Mother Earth,” said Ogen.

He said seeing waste transformed into a useful material brought a smile to his face.

Ogen hopes biofoam will create First Nations jobs that were lost when the pine beetle epidemic swept through their timber industry.

“One of our main goals is to make sure that our next generations are taken care of and made sure that they have good job opportunities,” he said.

“With this opportunity, we don’t necessarily have to look (only) at our backyard. There are other areas in Western Canada we could look at, even in the United States or overseas … I think there’s a great opportunity to make it a worldwide success.”

Biofoam’s texture is close to Styrofoam and can be similarly fashioned into different shapes. Its natural origins make biofoam slightly darker in colour.

While the specific ingredients remain a secret, it’s made by grinding the wood into fibre to create a slurry, then adding non-toxic chemicals, and finally putting the mixture into an oven at 80 C.

Jiang said the process is similar to baking.

“After a couple of hours, we take it out, just like a big cake,” said Jiang.

Investors and manufacturers are now being sought to launch a pilot plant to produce biofoam in B.C. next year.

A side benefit of the project could be mitigating forest fires that are fuelled by wood waste, Jiang said.

The project’s intellectual property is shared by Jiang’s team and the Wet’suwet’en First Nation, UBC said in a statement.

Jiang said environmental sustainability is his passion, and although it isn’t realistic to substitute all plastics with natural fibres, he wants to stress what he called the three Rs: reusing, recycling and replacing plastics.

“Whenever I see a product in the market, I always think: can we replace it with natural fibre? I also keep asking my students the same question. Throughout my whole career, I want to use my knowledge and expertise to create something that is beneficial to the society and to the planet,” said Jiang.

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
