No, it’s just one guy on a sit mower. It collects it as it goes or leaves it on the ground.
On larger roads they use a “roadside mower” which is a tractor with a robot arm trimmer that leaves the grass in the ditch. Still just one guy.
The latest development is to spread “wild” flowers instead of grass in the roadside. Supposedly to increase biodiversity, but I think it’s mostly virtue signalling. A roadside next to heavy traffic isn’t a great habitat for insects anyway. They also used one-season flower seeds, so they will have to seed it every year…which makes no sense for this purpose. On the positive side, it looks pretty and hopefully creates some awareness of the issue.
Yes, sure it can. Mashed/blended spaghetti bolognese or lasagna are available as baby food.
Baby food products are basically just ordinary food blended and packed in smaller convenient portions. Simply look at the package to see what it contains.
Cat and dog foods are completely different kinds of food, which is often made from animal biproducts and not suitable for human consumption.
