Mercer Group International and GK – C&D MRF Recycling

 by Sarah Maher,




Mercer Group International in Trenton, New Jersey had a problem. The material they had been processing was unique consisting of large wooden boards, plastic bags, and long plastic ribbons. This mix of material had been causing problems for their primary screen. The screen would jam every hour causing a 15-minute shutdown in which the employees would need to de-clog the unit. Knowing that General Kinematics would be there to support Mercer, General Manager Jeff Wilbur gave GK Territory Sales Manager, Rob Wasilewski a call. Rob knew that GK had been working on a new version of the FINGER-SCREEN™ that would be a perfect fit for this situation Rob went to work. In collaboration with Director or Resource Recovery, Dick Reeves, and the GK Engineering Department the GK team engineered a FINGER-SCREEN™ 2.0 to solve Jeff’s sorting problems.


The new FINGER-SCREEN™ 2.0 would throw material farther with a longer stroke, breaking down material further and relieving the issue of clogging. The new unit also features two alternating troughs to provide a drop leading to further material separation. Once the plan was solidified General Kinematics went to work building the unit and in late December the unit had been installed.


After the installation and a few tweaks, the FINGER-SCREEN™ 2.0 was ready to take on the unique material at Mercer. The large boards, plastic bags, and ribbons are now sorted with ease and the workers no longer need to shut down the process every hour, increasing their production. In an interview with Jeff Wilbur, he announced: “The FINGER-SCREEN™ 2.0 has increased our fines separation by one third.” Jeff is excited about the improvements that the new unit has been able to make and applauds the GK team for their commitment to taking care of his needs.


The team at General Kinematics looks forward to continuing the relationship and working together to improve the processing power of Mercer Group International.
