If you think of all products, which are labeled, and almost all of them, you can imagine the vast quantities of ink, paper and toner, not to mention the whole process that surely has an environmental impact. That is why increasing numbers of manufacturers are using recycled paper and packing products and even soy inks to reduce their carbon footprint. Xeikon’s dry toners for the packaging and labeling are an eco-friendly initiative to reduce the carbon footprint.

Its QA 1 dry toner is for industrial applications and its QA P is for printing. Dry toner digital printing is known for its eco-friendliness compared to traditional offset technologies – no VOC emission, less energy and less waste. The company has obtained FDA approval for direct and indirect food contact.

While a rocking chair may be thought to be the domain of grandparents, gently rocking away, it is a fact that rocking chairs can be extremely comfortable. And a newly designed rocking chair can also be used to generate electricity.

Ryan Klinger has designed this chair, named Empower, which was one of the finalists in the Greener Gadgets competition. Swinging or rocking on this chair which is hooked up to a kinetic energy generator and lithium-ion batteries, means that you will be producing electricity.
