    Ecologically, spiral foraging promotes responsible harvesting practices. Foragers are encouraged to take only what they need, leaving enough resources for wildlife and for the plants’ own regeneration. The spiral pattern naturally leads foragers away from heavily trafficked areas, allowing plants to flourish undisturbed. By leaving some areas untouched, foragers contribute to the preservation of biodiversity, ensuring that ecosystems remain healthy and resilient.

  • RE dispersible polymer powders, often derived from renewable resources, are characterized by their excellent solubility and dispersion characteristics. The 'RE' in the term stands for 'redispersible,' indicating the ability of these polymers to re-form into a stable solution after initial dispersion. This feature is particularly advantageous in processes where consistent and controlled dispersion is crucial.
  • Hydroxyethylcellulose, or Cellosize HEC, is essentially a non-ionic water-soluble polymer. It is created through the chemical modification of natural cellulose, primarily sourced from wood pulp or cotton lint. The HEC suffix denotes the attachment of hydroxyethyl groups, which significantly enhances its solubility and functionality in aqueous systems.
