Tableware Made With Remains Of Ceramics, Glass And Stone

Reusing 100% of waste to bring new household items to life is what makes Liverpool-based Granby Workshop.

This company uses crushed glass, old tiles, factory waste and other waste that would end up in the trash to create a line made entirely from recycled materials. Christened Granbyware, the collection consists of plates, bowls and cups.

We work closely with companies that specialize in waste management to identify a variety of raw materials that could be used for ceramic production. We crush glass, oxidize, sift sand and explore the extraordinary invisible processes behind the scenes in the wonderful world of waste management.

Issue.

Granby Workshop explains that in the UK millions of tonnes of ceramic, glass and stone waste end up in landfill every year. On the other hand, we still dig up tons of new raw materials. And what is the problem? Porcelain clay mining produces nine tons of waste for every ton of clay mined.

Solution.

It was with these problems in mind that the English company decided to develop materials entirely from waste, without binders or additives. In addition, the use of local materials was prioritized. See more details of the chosen articles, after many tests:

Industrial clay waste: Before water is returned to the supply network of a factory that produces tableware, toilets or any other ceramic product, it must be clean, so that all waste mud is filtered as waste. These super fine sewage particles are what bind the clay body together.

Recycled glass:  crushed into fine powder to form the base of the enamel.

Quarry waste:  slate, granite and marble dust. They add varying amounts of calcium, sodium, iron and potassium oxide, which in the correct amounts control enamel melting.

Recycled Refractory Bricks:  Kiln broken bricks, ground into powder. This provides alumina and magnesium, which helps melt, harden and strengthen enamel.

Ceramic waste:  broken dishes, tiles, bricks, bowls, crushed into fine powder. It is used to reduce shrinkage and enamel flaws, but also to add a touch of color.
