    At Ri-Thai we put our environmental and social commitments into practice while continuously striving for company growth. As early as in 2011 we began to introduce the line of MonoGreen™ monofilaments made from the following materials in pursuit of environmental sustainability.
    These eco-friendly monofilaments facilitate the transition away from the “take, make, use and dispose” linear economy system to the circular economy system where the “reduce, reuse and recycle” closed loops are implemented.

    Closing the "REUSE" Loop

    All color MonoGreen™ monofilaments are dope (solution) dyed, which leads to superior color fastness and less environmental impact in comparison with those by other dyeing methods. Furthermore,biodegradable monofilament is by nature more durable and proved less prone to shed microfibers in the wash than staple fiber and multifilament. When used in textiles, MonoGreen™ monofilaments enable better reusability and reduce microfiber pollution in the oceans.

    Closing the "RECYCLE" Loop

    Despite being a less sustainable alternative than reuse, re-manufacture or repair, recycling is an important and necessary component of a circular economy. This can be evidenced by the fact that an increasing number of recycled polymers are commercially available on the market.

    Closing the "CARBON" Loop

    “Anything that wears out or degrades during use belongs to the biosphere,” says Prof. Dr. Michael Braungart, who developed the Cradle to Cradle® design concept in 1990s. In his concept, materials are returned to the biosphere in the form of compost or bio-degradable waste, from which new materials can be created.
