HIGHKA pods are constructed from 95% recyclable materials and comply with the EU E1 formaldehyde emission standard — ensuring that the enclosed air environment of the pod receives zero VOC contribution from the pod’s own materials. For coworking operators who market their space on sustainability credentials (an increasing differentiator, particularly for enterprise clients with ESG commitments), HIGHKA’s material specification is documentable and verifiable. CE, UL, ISO 9001, and SGS certifications complete the compliance package.
