Addi. Flex® Biodegradability A visionary, easy-to-use and safe solution for the problem of plastic waste Eugen Karl Mössner Add-X Biotech For 1ο ΠΑΝΕΛΛΗΝΙΟ ΣΥΝΕΔΡΙΟ ΣΥΣΚΕΥΑΣΙΑΣ, ΤΡΟΦΙΜΩΝ & ΠΟΤΩΝ

Today, we have a huge problem: Plastic Waste

Addi. Flex: Biodegradability solutions One reason for the waste problem is polyolefins (e. g. , used in carrier bags) Example: § ~8’ 000’ 000 carrier bags are used each year in a typical EU country. § Up to 80% of them end up in the nature

Addi. Flex: Biodegradability solutions The waste problem is omnipresent, e. g. in backyards in Africa on waste mountains in England on waste fields in other countries

Solution: Biodegradability We mimic nature by using the environmental forces of heat, oxygen and sunlight to cause degradation leading to biodegradation

Addi. Flex: Biodegradability solutions The difference from Biodegradability: Instead of plastic waste fertile earth

Addi. Flex: Biodegradability solutions What is Biodegradability? A technology for degrading plastics § Biodegradable technologies depend on plastics in a biologically active environment (e. g. compost). The destruction of the material happens directly through the consumption by microbes. § Biodegradable technologies are different from degradable and oxodegrable technologies. Here the primary degradation depends on any combination of light, heat, stress and air. And then the consumption by microbes.

Addi. Flex: Biodegradability solutions What is Addi. Flex®? The Solution for Polyolefin Biodegradability Addi. Flex® is an eco-intelligent system of additives. The effects of adding Addi. Flex® to your plastics are: § Reduction of the Waste volume through complete biodegradation § Ecological Benefits § Economical Benefits § Less Energy § Mastering new legal requirements

Addi. Flex: Biodegradability solutions The features of the Addi. Flex® system § The most cost effective additive – less material for the same result. § The most effective additive on the market – initiation time could be controlled. § The highest quality and durability – high process ability in the manufacturing process. § The only oxo-biodegradable technique on the market suitable for basically all plastic processes.

Addi. Flex: Biodegradability solutions Overview on the benefits of Addi. Flex® § § § Complete bio-degradation 80%-90% waste reduction (in weight, not volume) Conventional raw materials and natural modfiers No toxic by-products (e. g. , methane) Less energy input vs. competitive products

Addi. Flex: Biodegradability solutions What happens when you add Addi. Flex® to your plastics (=polyolefins)? Microbes digest the biodegradable components and provide greater surface Temperature and oxygen will initiate the molecular breakdown of the polymer chains of the polyolefins: CH 3 -CH 2 -(CH 2)n-CH 2 -CHO 2 CH 3 -CH 2 -(CH 2)n-CH 2 -CH 3 -CH 2 -(CH 2)n-CH 2 + O 2 Reducing the molecular weight Weakening the structure The surface becomes hydrophilic and assists the third process: Microbes digest the polymer fragments. Result: H 2 O, CO 2 and biomass (no toxic breakdown componets).
