Challenges in Plastic Materials


Terms for participation 

1.   About Rotoplas and innwai 

Rotoplas, a company of Mexican origin with more than 40 years of existence and presence in 14 countries in the Americas, in 2019 created "innwai, the Water Innovation Hub", a communication channel with the water innovation and sustainability ecosystem that seeks to identify and capture innovative and sustainable solutions to solve various water problems. In 2020 we launched our first challenge addressed to entrepreneurs, SMEs and Civil Society Organizations. 

With this new call: “Challenges in Plastic Materials” we search, openly and permanently, for solutions expected to be of great benefit for Rotoplas in the long term.

Why participate? (benefits for the participants)

Our goal is to find researchers, start-ups and companies that are currently working to solve these challenges, so that we can: 

Establish a collaboration or partnership to implement the technology together. The type of collaboration or partnership will depend on the readiness of the technology and will be decided by common agreement,


Support them by giving them feedback and guidance about industry needs; either directly or participating as possible technology receptors within R&D projects funded by government or private, national or international, programmes that promote innovation.

2.    Characteristics of the solutions that Rotoplas is searching for with this call

 We search for technology developments that aim to solve the following challenge:

Challenge 1: Develop additives for polyolefin formulations that are friendly to the environment and offer physical properties, durability and antibacterial protection

I. I. Why it is important:

 Currently the additives in the formulations of plastic resins used in plastic transformation processes can be toxic and harm the environment.

II. Expected Result: 

 Alternatives that are friendly to the environment (biodegradable), harmless, and that facilitate the recycling of resins. They should also be low-cost, at least when manufactured in high volumes.
