Sustainability Impact =
Innovation + Integrity

Sustainability is central to our mission. We are devoted to developing innovative materials which can have transformational impact on our society, and we believe that truly impactful solutions need to be built based upon businesses with the highest standards of integrity. This is why we are working to minimize our operational footprint, while also striving to ensure high standards of sustainable sourcing and human rights throughout our value chain.

Transparent disclosures are the bedrock of our
commitments to society

Spiber’s reason for being is to contribute to the sustainable well-being of humankind, both now and for generations to come. Truthful, quantitative and transparent disclosure of the impacts that we have on the people in our society and the environment of our planet -both positive and negative -is fundamental in order for us to fulfill our purpose, and is a driver that will help us learn and improve, and to maximize the meaningful change that we bring to the world’s future.

As a first step, we have published our first Sustainability Impact Report which describes our sustainability strategy and covers disclosures regarding our global activities up until June 2022. Going forward, we plan to disclose updates on our progress and to report annually on this website.

Transitioning to circularity

The global shift towards a circular economy is an urgent agenda that must be accelerated. Spiber’s Brewed Protein™ material production currently relies on sugarcane and corn for our primary fermentation feedstocks in Thailand and the USA, respectively. Although we work hard to implement sustainable agriculture practices in these supply chains, we recognize that corn and sugarcane are ultimately food crops, and that some externalities associated with agriculture cannot be avoided.

Accordingly, we are committed to shift towards circular feedstocks in the future. For example, cellulose contained in agricultural wastes such as sugarcane bagasse or corn stover, or discarded textiles made of “Biosphere Circular” fibers, can be broken down into nutrients that can be upcycled and fed to our microbes for production of Brewed Protein materials.

Biosphere Circular:

materials and products that can be broken down into nutrients and re-used as feedstock for fermentation, including cellulose-based materials (which can be broken down into glucose) such as cotton, linen and rayon, and protein-based items (which can be broken down into amino acids) such as wool, silk and Brewed Protein.

Biosphere Circulation:

a resource circulation ecosystem where products created from Biosphere Circular materials are collected, broken down into nutrients, and used as fermentation feedstock to produce Brewed Protein or other fermentation products.

Minimizing our climate impact & product footprint

Climate change is a crisis that all of humanity must respond to robustly and swiftly. Water is a precious, shared resource, which must be used responsibly and protected from pollution. Fossil fuels are nonrenewable resources which will eventually be depleted. Excessive land use for agricultural production can cause loss of biodiversity.

We are committed to monitoring and mitigating the environmental footprints of our business and of our products, and we aim to achieve net zero greenhouse gas emissions by 2035.

Striving to ensure high standards of sustainable sourcing
and human rights throughout our value chain

Our mission to contribute to society will only bear fruit if we can guarantee that our entire supply chain upholds the highest standards of transparency, traceability, and accountability. Through the implementation of our Sustainable Sourcing Policy, we are committed to sharing our vision of a supply chain rooted in respect for the environment and human rights with our suppliers.

We understand the purpose of the “Guidelines on Respecting Human Rights in Responsible Supply Chains” prepared by the government of Japan and the “Guidelines for Responsible Business Conduct for the Textile and Clothing Industry of Japan” prepared by the Japan Textile Federation. We make the following declaration and will promote initiatives in accordance with these guidelines.
