FAQ: Hygovac® Bio

Hygovac Bio is an aspirator tube made entirely of sustainable bio-based polyethylene and comes in two sizes, providing an opportunity to choose a length which suits the treatment. The dual tips, with one traditional 45° end and one S-shaped, give the freedom of choice and increased patient comfort.


What material is Hygovac Bio made of?
Hygovac Bio is made of 100% bio-based polyethylene.

Why should I use Hygovac Bio?
You contribute to reducing the carbon footprint on the planet. Climate change is important to us and we believe that it is important to you too. That is why Hygovac Bio is made from renewable resources that make a significant contribution to saving and reducing the use of fossil resources and the level of greenhouse gas emissions. This means that it will help reduce global warming.

Produced from ethanol sugarcane Hygovac Bio is manufactured as a renewable raw material while traditional polyethylene uses fossil sourced raw materials such as oil or natural gas. This saves about 80% CO2 compared to ordinary plastic. There is no raw material with better influence on the environment than green PE.

Hygovac Bio is also available in two new sizes providing an opportunity to choose a length which suits the treatment. This providies the opportunity to broaden application of use with environmental purposes in mind. Less material is used producing the product and less storage space is required in the clinic.

What does renewable mean?
You have probably heard of global warming. It happens because today we use energy for everything we do. Producing this energy releases carbon dioxide (CO2) into the air. This CO2 contributes to the greenhouse effect, which increases global warming.

Plants absorb CO2 from the air as they grow. It is a way nature finds to fight against greenhouse effect. Sugarcane is one of these plants. Sugarcane is a type of plant that grows in Brazil. It is also called biomass, because it generates energy. Whenever energy is created from natural sources that can regenerate (meaning they never run out), like sugarcane, we call them renewable energy sources.

What is the difference between renewable and recyclable?
A product that is renewable comes from nature and can be regenerated in existing waste streams. The same amount of CO2 that is used in manufacturing the product is released at the end of the products life cycle, keeping the carbon in the system. A product that can be recycled can be reused and transformed into a new item.

Does recyclable plastic counts as renewable regardless of origin (fossil or bio)?
No, recycled plastic is recycled, from industrial or post consumer the renewable share will increase only when we start using more fossil free plastic.

Is bio-plastics guaranteed to be non-toxic?
Generally plastic is, with a few exceptions, very clean. PE and PP are the simplest materials. The bio-based material must comply with the same regulations as others regarding REACH, food approvals etc. like all other plastics. The plastic Hygovac Bio is made from is called bio-polyethylene and is non-toxic, there are no components added.

How is Hygovac Bio and the Bio-based Polyethylene material produced?

1. When humans use energy in their day to day activities, CO2 is released into the air
2. Sugarcane capture Co2 from the atmosphere during its natural photosynthesis process
3. Sugarcane is used by mills as a raw material and is transformed into ethanol
4. This ethanol is then used to make bio-energy to meet the needs of the production process
5. Orsing use Braskem’s Green Plastic to make Hygovac Bio aspirator tubes
6. After Hygovac Bio has been used, these plastic products can be 100% recycled


Where does the sugarcane grow?
The sugarcane plantations are located in the South-Central region of Brazil, more than 2,000 km (1,200 miles) from the Amazon Region. The expansion of areas used to plant sugarcane is governed by Sugarcane Agroecological Zoning. The ethanol used to make the polyethylene is purchased from different suppliers that are selected accordingly with the Code of Conduct for Ethanol Suppliers, which takes into account aspects related to compliance with Brazilian Law and respect for biodiversity.

Does sugarcane cultivation use rainwater or artificial irrigation methods?
Sugarcane in Brazil is practically not irrigated. Water needs in the agricultural phase are resolved naturally by the rainfall of the producing regions. This is one of the reasons why it is better to produce the sugarcane in Brazil compared to a greenhouse in Europe.

Is the sugarcane cultivated in a socially responsible manner?
Yes, sugarcane cultivation is conducted in accordance with Brazilian law and the rules and labor conditions established by the International Labor Organization (ILO) that should be followed by all employers, which are subject to regular inspections by the government.

The I'm greenTM Polyethylene has been certified by renowned international laboratories and organizations, see Bon Surco certificate: https://www.braskem.com/site.aspx/Certifications-pe

What is I'm green™?
I'm green™ is the brand created by Braskem that identifies the products in its portfolio produced from renewable sources. To identify products that have I'm green™ Polyethylene in its composition, and to help the consumers to recognize them, Braskem created the I'm green™ seal.. For use of the I'm green™ seal, products must follow certain criteria established by Braskem.

Why is Hygovac Bio shorter than the other Hygovac aspirator tubes?
Hygovac Bio is available in two new sizes to meet the need from hygienists and dentist working without assistance. The shorter aspirator tube is 95 mm and is therefore ideal for hygienists and will give an easier access when working without assistance. This provides the opportunity to broaden application of use and since less material is used producing the product and less storage space is required in the clinic it has environmental purposes in mind.

Can I autoclave Hygovac Bio?
No, Hygovac Bio is not autoclavable.

Does Hygovac Bio have an expire date?
The expire date for bio-based polyethylene is equivalent to fossil PE.
