Italians gear up for plastics show with new offerings Over the past two years, the plastics and rubber machinery industry in Italy has achieved stable growth, according to Italian industry association Assocomaplast. Exports and production values were mainly fuelled by market demand from China, Germany, France and the US. In 2011, export value increased more than 20%, with Asia accounting for 19.2% of exports, and production value grew by 11% to hit EUR4 million. It is against this backdrop that Italian technology providers will introduce value addons to attract visitors to this year’s PlastMilan exhibition, to be held from 8-12 May.

More biodegradable, recyclable materials Besides promoting healthy living and sustainable transportation, cycling will become greener as Portugal-based Polisport has developed a biodegradable water bottle for cyclists. It is made from API’s Apinat bioplastic that performs just like PP or PE but decomposes under controlled composting conditions.

Polisport says it has produced thousands of biodegradable bottles using extrusion blow moulding without modifying the equipment.

Compounder Finproject will present Biolevirex (polyolefins) and Biofinpro (PVC) materials that can be used in multiple markets and are compliant with EU94/62CE for aerobic biodegradation.

In machinery, granulator maker Exact has developed a system for recycling EVA edge trims produced from EVA roll stock used for manufacturing solar panels. Integrated with an extrusion line, the system recycles without the use of heat, thus allowing the recycled trim to be turned into sheet. Once the EVA film enters the unit, tension is controlled with a dancer system and the material is compressed. With thicker materials, heat is required for improved Exact’s new machines for recycling EVA compression. The material is then cut film trims into small wafers that are transported and mixed into the extrusion process. The closed loop system does not require additional handling of the chip, minimising cross contamination.

Technopoly, a static and rotary machine specialist, is currently developing a special head to handle PU granules obtained from waste material. It will also showcase its latest mini head for micropouring as well as special heads for mixing PU that are said to be easy-to-use and self-cleaning.

Having invested 5% of its sales into R&D, granulator maker Gamma Meccanica will show its GM65 Compac pilot line for recycling. It is made up of a cutter, GM65 extruder and filter. The cutter-compactor comes with the Ecotronic controller that allows materials with a residual moisture up to 15% to be recycled; a constant temperature with up to 40% energy savings and no use of water. For dry, non-degassing materials, a non-vented extruder can be used. Alternatively, an extruder can be installed with the standard double degassing vents. An in-line viscometer undertakes real time viscosity measurement.

Besides developing a PU waste handling system, Technopoly will introduce a new line of machines for the production of technical items

Rotomoulding takes on a green theme Sustainability is being applied in all machinery facets including rotomoulding. Caccia Engineering has designed a machine with an exhaust gas modulation (EGM) system for the dispersion of gasses to help reduce the carbon footprint as well as cost and energy consumption.

The EGM is realised through a variable speed extraction fan, which operates in line with the load percentage of the digital burner and is monitored through a software. In addition, a turbo fan system increases the total efficiency of the combustion
