Each Miinus kitchen has been built on ecological values. Indoor air and carbon footprint calculations guided us to identify natural, clean choices for each material used. However, pure materials alone are not enough to guarantee a pure product if the manufacturing methods do not live up to the same high standards. Miinus kitchens are manufactured at Puustelli’s production facilities, where ecological values have governed our manufacturing methods for many years.

Miinus door structures differ from ordinary board structures. When considering the ecological values of door structures, we quickly identified that utilising a honeycomb substrate had many advantages.

A honeycomb-core door is lighter, it does not exert excess stress on cabinet hinges or other mechanisms and it helped prevent bowing issues long associated with tall doors in particular.

Our honey-comb core veneer door selections have solid wood frames and are enveloped in a variety of beautiful, real wood surfaces.

The surfaces are treated with water-soluble substances or natural oil and glues used in assembly contain no added formaldehyde.

Using a honey-comb core for our doors means they are lighter in weight and consequently lessen fuel consumption during transportation.  Our Solid Wood doors, although not as light, retain ecological values of the Miinus range in that they are sourced from highly sustainable Finnish forestry.

At the development stage of the Miinus kitchen and as our research progressed, we found we needed to change the carcase material. However, there were no alternatives available to the existing traditional materials used. Much research and numerous tests were required to help find a solution. Several years of development finally bore fruit. Biocomposite was chosen as the carcase material and resulted in the pioneering Miinus carcase, the side frames of which are made by injection moulding. Biocomposite is an ecological and completely recyclable material, the greatest advantages of which are its lightness, durability, modifiability and purity. Lightness makes it easier to move, install and enable reduced transport emissions. The material’s durability embraces indefatigability, which allows a product to be moved, installed and dismantled time and again.

Other advantages not found in ordinary carcase materials include water-resistance and an ability to withstand hot and cold temperatures.

Worktops in Miinus range comprise of wood and ceramic. Both are re-useable and recyclable ecologically sustainable products.

Miinus solid wood worktops come in thicknesses of 30 mm and 38 mm and the surfaces are treated with gentle natural oil. The solid woodworktop can also be stained. The glues we use in manufacturing our worktops are free from formaldehyde. We can make a moulded edge for the solid wood worktop if you require. This allows a harmonious moulded edge if you wish to place a ceramic worktop and a solid wood worktop side by side. Our clean manufacturing process ensures a pure product, which has the top indoor air rating M1.
