visitors got the chance to guess the combined weight of three compact & bale briquettes for the chance to win £50 in amazon vouchers.made from pet bottles, aluminium cans and polystyrene waste, compact & bale said that visitors marvelled at the compaction ratio achieved on such materials.the competition, at the event colocated with packaging innovations, got people thinking about waste materials that can effectively be compacted to dramatic ratios and this provoked many discussions with visitors on what machines could condense materials down to such a degree.&ldquowe were happy to discuss the strautmann&rsquos &lsquoautomate to save&rsquo range which has revolutionised manufacturing, distribution centres, household waste recycling sites, waste contractors and other sites with eps waste globally,&rdquo said a compact & bale spokesperson.the strautmann autoloadbaler, for example, is described as the world&rsquos only selfloading vertical baler, &ldquothis machine&rsquos ability to massively reduce labour costs and time ensures that staff may always be front facing, with no time wasted filling a baling press and waiting for the cycle to end.&rdquoalso popular with visitors was the liquidrainer which offers automatic, quick and profitable emptying of filled liquid containers, taking over the job automatically by using a rotor to perforate filled pet bottles, tetrapak and beverage cans.and for polystyrene waste, the styropress eliminates the common issues of screw type systems which overheat material, jam and result in costly downtime and the problems that come with storing large amounts of loose eps until the screw has cooled down again &ndash &ldquosome visitors found it hard to believe that a briquette so compact could be produced with no heat.&rdquo&ldquothe show proved to be a busy one and there were many entries for the guess the weight competition but the final congratulations goes to barry dunne of thamesdown recycling who made the closest guess at 5.5kg, just 0.212kg from the correct answer.&rdquo
