The TWIN concept

Innovations in the field of sustainable materials, including biobased substances and composites made from residual waste, provide a wealth of opportunities to make the Streetlife Collection more sustainable. After many years of research and development, we have now introduced our TWIN concept, a series of materials that form a fully-fledged alternative to hardwood.

Sustainability & alternatives

Global awareness of growing waste streams, environmental pollution, rising CO² emissions and the depletion of natural resources has led to new ideas in sustainability, such as Cradle2Cradle (C2C) and the circular economy. These two concepts are aimed at improving the efficient and effective use of the natural resources available to us. Streetlife’s design philosophy dovetails well with these principles.

After many years of research and development, we have now introduced our TWIN concept, a series of materials that form a fully-fledged alternative to hardwood.

By adding this new identity to our product families, TWIN offers landscape designers and architects more freedom of choice.

Sustainable material
Heavy-Heavy Bench (Lava Grey) - Leiden

Lava Grey

Lava Grey is made entirely from recycled household plastic waste, such as packaging, cups, bags and trays. It consists of around 75% recycled PE and 25% recycled PP. This new anthracite grey substance has a fairly rough texture. In certain places, the surface reveals how the material flowed into the mould during the casting process, like a lava stream. Pieces of coloured plastic are visible here and there in the grey mass, highlighting the origin of the recycled material. Colour and texture may vary in North America due to local production.

All Black

All Black is made from industrial and household waste plastic. This includes plastic bags, building and agricultural plastics, bottles, caps and beer crates. The material is essentially composed of two thermoplastics: PE and PP. All Black has a matt appearance and a rough texture and is black throughout due to the use of a natural dye (carbon). The colour is retained by UV stabilisers.

Cloudy Grey

Cloudy Grey is a recyclate of materials sourced from plastic and textile waste. It consists of 50% recycled LDPE plastic combined with 50% recycled textile fibres (from used clothes). This durable, grey material with blue tones has a matt appearance and an uneven texture. Fibres of coloured clothing add to the vibrant marbled aspect, affording Cloudy Grey a unique character. Because of the material’s limited rigidity, the maximum length we use in our products is 120 cm. Colour and texture may vary in North America due to local production.

Bamboo Brown

Bamboo Brown is made from an extremely fast-growing, giant bamboo species with a very high capacity to absorb carbon dioxide and produce oxygen. Its fast growth rate ensures that stems can be harvested after four to five years. The process of compressing the long bamboo fibres under high temperature and pressure give this material its deep brown colour. Over time, Bamboo Brown ages with exposure to light and air. The visible fibres give the smooth surface attractive variations in colour and structure. Bamboo Brown is carbon neutral, can be recycled into chipboard or used as fuel for bioenergy production in the end-of-life phase.

TWIN materials

Streetlife designs focus on inspiring, sustainable solutions for green public spaces. Streetlife’s aim with the TWIN Concept is to combine aesthetics and sustainability in fair, future-proof products. Thanks to the TWIN Concept, all Streetlife products featuring FSC certified hardwood beams are also available in a durable twin material.
