Prototypes of the novel GreenSpense gas-free dispensers

Propellant-free dispensing technology from GreenSpense unleashes new options for packaging materials and designs.

The Need

Aerosols and continuous dispensers are widely used to dispense sprays, foams, or gels. More than 12 billion aerosols are sold annually worldwide (FEA 2012 Annual Report) and dispense products for personal care, household, technical items, food, pharmaceuticals, and more.

Aerosols provide an efficient and convenient user experience. But, safety risks; packaging limitations; added production, storage, and transportation costs; and pressure from green organizations and government regulations — all due to the use of pressurized gas — are driving consumer product manufacturers and brand companies to search for environmentally friendly, safer, and more cost-effective dispensing solutions.

The Product

GreenSpense’s Eco-Sleeve enables gas-free continuous dispensing that eliminates the need for pressurized canisters and maintains the desired convenient user experience. The Eco-Sleeve generates high pressure (that is directed to the center of the package only) and enables innovative packaging designs with low-cost, recyclable materials such as plastic or cardboard. Easy to implement in production lines, the patent-pending technology works with dual-compartment dispensers, exerting consistent pressure throughout the entire dispensing process.

The Advantages

  • Allows manufacturer differentiation through the use of new packaging materials and shapes
  • Significantly reduces the costs of filling and packaging
  • Saves storage, transportation, and handling costs
  • Environmentally friendly, gas-free, recyclable, biodegradable
  • Maintains the desired user experience and convenience of aerosols by providing continuous self-dispensing

The Team

  • Gadi Har-shai, CEO, CTO, and Founder: More than 20 years of experience in various high- and low-tech industries, managing complex projects and organizations for global companies, including Objet-Stratasys (Nasdaq: SSYS), Creo-Kodak, Orbotech (Nasdaq: ORBK), Iscar Metalworking (Berkshire Hathaway)
  • Amir Biran, CMO and Founder: More than 20 years of executive experience, CEO at Zoomix Data Mastering (led a $30 million acquisition by Microsoft) and Viola Networks, and in positions at Better On Line Solutions and Elbit Systems

The Market

According to the European Aerosol Federation, more than 12 billion aerosol units are manufactured worldwide each year, generating over $40 billion in end-product sales (2010-2011 annual report).

Industry experts estimate the dual-compartment segment of the aerosol market currently accounts for about 15% of aerosol units. Sales of dual-compartment packaging components are estimated at $1.4 billion annually. The flexible packaging market (collapsible tubes and squeeze bottles) is estimated to reach $70 billion by 2015.
