Make the most of your compost by transforming it into 3D printing filament

This student start-up turns your food waste into high quality bio-plastic

We’ve previously written about the role that 3D printing can play in the future of food, but could additive manufacturing also have a part to play in disposing of food waste? Indeed it can, claim the brains behind a startup called Genecis, made up of graduates from Canada’s University of Toronto Scarborough. With this ambition in mind, they have developed a way to transform today’s restaurant food waste into tomorrow’s biodegradable plastics — useful for everything from creating packaging to 3D printing filament.

“Genecis uses biology to convert organic waste into higher value materials,” Luna Yu, founder and CEO of Genecis, told Digital Trends. “The first product line is PHA (polyhydroxyalkanoates) biopolymers, which is used in combination with PLA to make 3D printing filaments. It is also used to make high-end flexible packaging and containers. In addition, PHAs makes a tougher and less brittle 3D printing filament. The end product is 100 percent biodegradable, and can be mixed with a variety of colors. Currently, all PHAs are made from expensive food crops such as corn, sugar cane, and canola. Genecis has developed a novel technology that produces PHAs from mixed food waste, dramatically reducing the production costs.”

The core of Genecis’ technology involves what Yu describes as “special recipes of bacteria.” These assemble materials automatically at rapid speeds in a way that can be used to produce rare chemicals or materials which are expensive to create chemically.

“Over the past two years, Genecis has collected bacteria from all around the world, and isolated over 200 species that are not present in any existing database,” Yu continued. “This allows us to start developing our own synthetic biology platform, which rapidly creates new synthetic bacteria. These bacteria can be used to make better PHAs for 3D printing, and reprogrammed to make higher value materials used in the cosmetic, pharmaceutical, and nano-materials industries.”

Currently, Genecis is working to commercialize its first product line consisting of PHA bioplastic pellets. It is also seeking partnerships for users of its manufactured polymers. In other words, if any readers happen to be 3D printing filament makers, packaging manufacturers, or general plastic manufacturers that currently use PHAs, now is the time to get in touch!

AMD might be about to launch the most powerful laptop of 2023
AMD's 3D V-Cache chip.

It appears that AMD's revolutionary 3D V-Cache tech might be on its way to laptops, and the laptop that gets the 3D treatment might be one beastly computer.

A Ryzen 9 7950HX3D chip has been spotted inside an Asus ROG Strix laptop. Will the 3D V-Cache make this device top every ranking of the best laptops, or will it just become a power-hungry desktop in a smaller package?

3D printed cheesecake? Inside the culinary quest to make a Star Trek food replicator
a slice of 3D printed cheesecake

Along with jetpacks, holograms, and universal healthcare, one of the great unfilled promises of the Star Trek-style future is the food replicator. Few concepts hold more sway over both the keen foodies always on the lookout for the latest trend in dining and those of us who can barely be bothered to put a frozen pizza in the oven than a box in your home which can create any meal you desire.

You press a button, and the machine whirs and beeps and creates the delicious dish of your choosing, no tedious chopping or marinating or pan-searing required. It’s an idea far too good to be true — but we might be one step closer to this paradisiacal utopia than you think.
How to 3D print a cheesecake
Researchers from Columbia University recently managed to 3D-print a cheesecake, in a process that is exactly as delightful as it sounds. They detailed their discoveries in an article in npj Science of Food, and we spoke to lead author Jonathan Blutinger to learn how they did it.

If you already have one of AMD's best processors for gaming, such as the Ryzen 9 7950X3D or the Ryzen 7 7800X3D, both your CPU and your motherboard might be in trouble.

Several reports of the processor burning up have recently surfaced. While AMD hasn't made any statements, it's possible that a new BIOS update might be enough to keep your gear safe.
