clever pack says its caps leave the factory with two lives already, the first being an effective plastic closure system and the second being a plastic mounting block that is compatible with other caps and legolike building blocks already on sale. the environmental impact is much smaller as the caps do not have to go through the plastic recycling process. the caps, says the company, only leave a small environmental footprint, are economically viable and can be turned into toys for poor children, artistic tools and instruments to encourage environmental awareness. source httpwww.europeanplasticsnews.comsubscriberfeatured2.htmlcat1&featuredid4…
