CalPlant create rice-straw based MDF panels

With MDF being such a widely used product, it would seem an obvious choice to include a company who are seeking out new, highly sustainable ways of creating a product of the same use. CalPlant are using rice straw, an agricultural waste which has no other uses due to its lack of nutrients to create an upcycled medium-density fibreboard (MDF) product. Experts expect rice straw MDF boards will have better moister resistance than conventional MDF because of rice’s naturally waxy essence. These are just a few of the reasons that make this company a noteworthy feature on our list of sustainable products.


There are a number of accreditation assessments available to manufacturers. Set by third party organisations such as BREEAM, LEED, UL and C2C, they offer prospective specifiers the opportunity to understand and evaluate what sustainability standards a given material may offer their project.

Wherever possible we showcase materials that have some form of accreditation but also recognise that acquiring them can be a costly and time consuming process, particularly for smaller brands.

We believe in transparency and think that an honest approach to materiality is key to making more sustainable decisions when planning our built environments.

We seek and promote material manufacturers that:

  • Consciously endeavour to choose raw materials based on provenance and quantity required
  • Aim to reduce the energy needed and pollution created in the production and transportation of their materials
  • Reuse resources and waste
  • Create regenerative materials
  • Utilise closed-loop production methods
