Briefly tasks framed in red in the picture below have been performed so far, while the rest are currently ongoing and are foreseen to be completed on schedule in August 2014.


Action 2: Requirements of products and equipment

During the implementation of Action 2, which concluded in December 2011, the following activities were successfully performed: study and identification of plastic waste from different waste management and collection centers and definition of technical requirements of polyolefin mixtures to be treated in the recycling pilot plant. Different tests were performed in the prototype drum with capacity of 200 kg/hour and Life Cycle Analysis of recycled LDPE was carried out in order to compare it with virgin LDPE.

Action 3: Pre-treatment of post-consumer polyolefin mixtures

Action 3 began in January 2012 and was concluded in September 2012. During the development of this action, a comprehensive study, analysis and evaluation of already existing techniques for treatment and conditioning of waste plastics were carried out in order to obtain a material input as homogenous and suitable as possible for the recycling demonstration line.

Action 4: Design of thermal treatment prototype – Phase 1.

Action 4 ended in August 2013 and objectives set out in the project proposal were successfully achieved. Thus, during the development of this action, prototype equipment for thermal processing was designed and built, whereby the most appropriated thermal contraction of the post-consumer polyolefin mixture was achieved.

Tests with simulated samples to optimize additive concentrations and processing conditions




Extrusion-blowing with LDPE pellets from simulated samples with Lurederra’s equipment


Production of pellets from HDPE/PP from simulated samples with SMSA’s equipment



Extrusion of the HDPE/PP compound with additives from simulated samples


Action 5: Design of separation equipment – Phase 2

During Action 5 separation equipment based on pneumatic separation by air flow and on electrostatic separation was designed. After carrying out some small-scale tests the pneumatic separation system was finally chosen.

Action 6: Recycling tests in the new plant

Action 6, which began on January 2014 and is currently ongoing, consists of assembling and connecting the different elements in the recycling pilot line, and subsequently carrying out the corresponding tests with thermal and pneumatic separation equipment. These tests are to be carried out by PHB-MOS by using real samples proceeding from different sources proceeding from Lurederra-SMSA.
