A new kind of wood-based plastic could enable circular home ... - Science Daily

Plastics used in home furnishings and constructions materials could be replaced with a new kind of wood-based degradable plastic with semi-structural strength. Unlike thermoplastic, the material can be broken down without harm to the environment, researchers in Sweden have reported.
One of the goals of renewable wood composite development is to make materials strong enough to replace fossil-based materials used in home construction and furnishing, such as bathroom cabinets, doors, wall-boards and countertops. And it needs to be sustainable, or circular.
"Degradability enables circularity," says Peter Olsén, a researcher at KTH Royal Institute of Technology in Stockholm. "By degrading the plastic, the fibers can be recycled and the chemical components from the plastic reused."
High fiber content is the key to the strength of materials like fiberglass, but it's difficult to deliver a degradable wood composite without intensive heat damage from processes like melt-compounding.
Olsén and fellow researchers at KTH report that they've found a way to deliver both high fiber content and degradability.
"No one has been able to make a degradable plastic with fiber content this high before, while having good dispersion and low fiber damage," Olsén says. "This enabled the material properties to be improved dramatically compared to previous attempts."
In order to achieve higher fiber content, the researchers combined polymer chemistry with process technology similar to what is used for carbon fiber composites.
Everything is based on cheap and available raw materials, Olsén says. The degradation products are also harmless to the environment, and can be reused -- enabling what Olsén calls "a fully-circular product concept."
And it could actually save trees. "It invites recycling of wood fibers to enable reformation of the material," he says.
But in order to move on to commercialization, Olsén says the formula needs to be optimized. "The key to the work is that it shows a new way of how we can create degradable biocomposites with high fiber content," he says.
Their findings were reported recently in the scientific journal, Nature Communications.

8 Small Pantry Ideas to Free Up Space in Your Kitchen - Yahoo Life

Stay organized even in the smallest pantries with these smart tips to maximize space. Anthony Masterson Between cramped corners, poor lighting, and multiple people rummaging through contents daily, small pantries can be tricky to keep organized. If you’re working with a small or practically nonexistent pantry, it can feel downright impossible to make room for everything, let alone keep it tidy. Fortunately, there are plenty of small-pantry storage ideas. Between simple DIY projects and innovative solutions, we’ve rounded up ways to make the most of what you’ve got. Get inspired with the following small pantry organization ideas for your own home. When pantry space is at a premium, it’s important to be resourceful. Turn cabinet doors into extra storage with shallow shelves. They can be affixed to the inside so long as there’s clearance for the door to close. Dowel rods keep small items, such as spices and condiments, in their place. Arrange larger bags and boxes of snacks directly on the shelves of the cabinet. To optimize vertical space, especially if your small pantry lacks adjustable shelving, stack cans and containers whenever possible. Whether you’re working with a small closet or a bit of blank wall space, a customizable track system can do wonders to keep pantry goods organized. These closet systems can be installed by a professional or on your own if you're handy. Open shelves and pull-out drawers can be added and adjusted as your needs change. To optimize track shelving in a small pantry, decent ingredients into food-safe containers and incorporate a lazy Susan for condiments and risers to organize cans. Marie Flanigan Think outside the box, or even the room, when it comes to organizing a small pantry. While most food items belong in the kitchen, overflow can be stored off-site if necessary. Give new life to a closet in the mudroom, laundry room, hallway, or basement if it’s temperate. Store bulk buys, such as cans and bottles, for anything you need to replace in the main pantry on a regular basis. Laura Moss For tight spaces, a narrow pull-out cabinet can be a game-changer for pantry storage. Purchase standalone rolling units that fit the dimensions between gaps anywhere in the room, or install one as part of the cabinetry for a camouflaged look. On the slim shelves, line up cans of soup, boxes of pasta, and bags of snacks by category. Before heading to the grocery store, simply slide it open and do a quick scan of inventory. Everything should be clearly visible and yet hidden away when not in use. Anthony Masterson Deep cabinets might seem like an asset, and they do make sense as a spot to store pantry goods, providing plenty of room for bulky boxes of pasta and cereal along with big bags of chips. However, smaller items like cans and jars undoubtedly get lost in the mix. Prevent expired food by installing pull-out drawers either in lieu of shelves or directly above them. Roll the drawers out to see exactly what you have on hand without making a mess or winding up with food waste. James Schroder Even in a small walk-in pantry, decanting non-perishable goods is a smart move to save as much space as possible. Everything from pasta and cereal to rice and lentils and even crackers and chips can be stored in airtight canisters to get rid of bulky or awkward packaging. Use coordinating bins to house snacks, including individual grab-and-go items. Even pantry-friendly produce, such as potatoes and onions, can be sorted and kept in baskets. In addition to maximizing space, this method allows you to see and reach for anything you need with ease. Ed Gohlich If a pull-out pantry doesn't have enough space to fit your family’s needs, add some shelf storage nearby. Hang a handful of floating shelves to hold everyday items such as tea bags or the snacks that kids ask for regularly. Since they’ll be out in the open, consider decanting the items into matching jars or bins to keep visual clutter to a minimum. While you’re at it, follow this method for anything in the pantry. Airtight food containers not only keep things fresher longer, but they also help maximize space, especially if you can stack them. Edmund Barr This idea is ideal for temporary situations, such as if you’re renting or saving for a future kitchen renovation. A stylish stand-alone cabinet can serve as a perfectly hidden pantry. Find one with doors that fits your style, space, and stuff. You can even recycle and refinish a vintage find to keep storage personal and eco-friendly. Within the cabinet, sort your stuff by category to keep your small pantry organized. : Keep your household cleaners out of sight but always on hand. If you're ever been in the process of baking a pie, cake, or tart and been a few tablespoons of butter shy of what's needed, try these substitutes. When it comes to keeping things tidy, you can't go wrong with the best shoe organizer. Whether you live in a place where it snows most of the year, and you need to keep your boot collection in check, or you're someone who owns boxes and boxes of heels, rest assured that your stems are in good hands. From affordable shoe racks that hook onto the back of a door (freeing up your valuable floor space) to luxurious cabinets that fold out to reveal specialized compartments for your favorite pairs, these shoe organizers are nothing short of impressive. Baked salads, salads in which all of the ingredients are baked, are taking over TikTok. Here's what they are and how to make them. Spitting is important for brushing teeth and eating, but it takes years for kids to master the skill. "The View" co-host gets candid about her struggle with body image.

New bill in Maui will restrict outdoor lighting to protect birds - The Washington Post

Sign in
In 1886, after meeting the inventor Thomas Edison in New York, Hawaii’s King Kalakaua enthusiastically began electrifying the grounds of his new residence — and within a year, 325 incandescent lights had the Iolani Palace fully aglow.
The king wouldn’t be able to pull off the same feat these days on Maui. Much of the island’s outdoor illumination soon could violate a new ordinance intended to help the island’s winged population. Fines could reach $1,000 a day.
The measure restricts outdoor lighting in an effort to keep endangered birds — and Maui has some of the world’s rarest — from crashing into spotlighted buildings. But Bill 21, signed into law last week, is ruffling feathers because its provisions also could keep flagpoles, church steeples, swimming pools and even luaus in the dark.
“People have told me they’ve seen birds falling on the ground in town, up country, all over the place,” said the bill’s author, Kelly Takaya King, who chairs the Maui County Council’s Climate Action, Resilience and Environment Committee.
Maui is a veritable Eden for species such as the wedge-tailed shearwater, white-tailed tropicbird, brown booby, myna, kiwikiu and nene — the state bird and the world’s rarest goose.
The island also is home to some 170,000 people, however, and the new law is pitting the avian paradise against the human one. The ordinance imposes a near-total ban on upward-shining outdoor lighting and limits short-wavelength blue-light content. Similar laws are in effect in many jurisdictions nationwide to protect various local interests, including the night skies in Arizona and the wilderness in New Hampshire. Maui has a more complicated set of priorities.
The outdoor light restrictions effectively prohibit nighttime hula dances and luau performances — local cultural signatures. Indoor alternatives are impractical. “Customers do not want to be in a ballroom or enclosed facility — they can go to Detroit and do that,” wrote Debbie Weil-Manuma, the president of a local tourism company, in a letter of opposition.
At the same time, Maui is grappling with an invasive species arriving in flocks of up to 35,000 a day: tourists. Local officials are considering caps on hotel and vacation rentals.
Birds can be disoriented by artificial light, sometimes confusing it for moonlight, and end up slamming into a building’s windows or circling until exhausted. In a single night in May 2017, 398 migrating birds — including warblers, grosbeaks and ovenbirds — flew into the floodlights of an office tower in Galveston, Tex. Only three survived. This danger is why the Empire State Building in New York City, the former John Hancock Center in Chicago and other landmark skyscrapers now go dark overnight during peak bird migration periods.
One tall building. One dark and stormy night. 395 dead birds.
Yet, most mass bird fatalities occur in urban centers with tall buildings in high density. Maui is rural, and its kalana, or county office building, is only nine stories tall.
Jack Curran, a New Jersey lighting consultant who evaluated the science behind the bill, said the council “clearly didn’t do their homework.” The bill also requires that lighted surfaces be nonreflective, with a matte surface if painted. As the island is coated in compliant black paint, Curran joked, “Maui will wind up looking like Halloween.”
Even support for the regulation is fractured. “This bill does provide good benefits,” said Jordan Molina, Maui’s public works director, “but it doesn’t have to do so recklessly.” The new law, he added, will make his office the “blue-light police.”
Although the U.S. Fish and Wildlife Service did not oppose the bill, it recommended creating a habitat conservation plan unless the county could devise a foolproof lighting policy.
According to public records, the council relied on a single, non-peer-reviewed study funded by an Arizona company, C&W Energy Solutions, that lobbied for the bill. (The county’s attorneys issued a memorandum in July warning of the “potentially serious conflict of interest,” which the council ignored.) And King’s efforts were propelled in part by conservation groups’ lawsuit alleging that a luxury resort’s lights disoriented at least 15 endangered petrels between 2008 and 2021, resulting in at least one petrel’s death. (By contrast, the Maui Forest Bird Recovery Project has focused on the continuing “depredation by feral cats,” which number in the thousands on the island.)
Still at issue are the measure’s conflicting exemptions. For example, lights at public golf courses, tennis courts and schools’ athletics events are allowed, but not lights at hotel-owned golf courses or tennis courts. Conventional string lights are permitted for holidays and cultural festivals but must be “fully shielded” for all other uses, including weddings. The county fair is also exempt. So are emergency services and emergency road repairs.
The law will inhibit TV and film crews’ night lights, such as those used by “Hawaii Five-O,” “NCIS: Hawai‘i” and “The White Lotus.” The latter was honored in October by the Maui County Film Office for giving the island national and international recognition.
To guard migratory birds, Philadelphia plans to cut its artificial lighting that can fatally distract flocks
King told local media that compliant lights are widely available online. But when asked recently for online links to such bulbs, her office sent just one — for a bedside night light that can double as an outdoor bug light, although it was unclear whether the bulb meets all of the ordinance’s specifications.
“Appropriate lighting is not available,” King then conceded. “We’re hoping it will be in the next few years. When you pass a lot of these environmental laws, you kind of have to go in steps to get them passed.”
As passed, the bill explicitly removed exemptions for field harvesting, security lighting at beaches run by hotels or condominiums, safety lighting for water features, motion-sensor lighting, and lighting on state or federal property — including Maui’s harbors and even the runway lights at its airports.
Council member Shane Sinenci supported the ultimate provisions. “Our unique biodiversity is what makes us appealing to both visitors and to residents alike,” the Maui News quoted him as saying before the final vote. “We are often underestimating the value of a healthy ecosystem and all the benefits that comes with it.”
The law takes effect in July for new lighting and requires existing lighting to be in compliance by 2026.
