Molson Green increase
their machine portfolio
Founded in 2016 by Johann Doppstadt, who is seen by many as one, if not the leading creative minds in the industry. His latest creation under the J. Doppstadt brand is the GT 130A De-Stoner which will be marketed in the UK by the Molson Group under their recycling focused Molson Green division.
Recently, Molson Green held a VIP demonstration event of the Doppstadt De-Stoner to introduce this versatile machine to the recycling market and the HUB-4 team were invited to see the De-Stoner within a processing line-up.
The two-day event was held at Laverstoke Park Farm (LPF) which is spread over 2,500 acres of rolling Hampshire countryside near Overton. Owned and run by ex-racing driver and Formula One World Champion Jody Scheckter, one element of the LPF business is green waste recycling which involves the supply of compost to biomass facilities.
Currently the business processes in excess of 30,000 t/year of green waste which originates from landscapers, hedge trimmers and municipal contracts.
Efficiency is always a key element in any processing function and the current operation at LPF required some improvement which led to a trial set-up to demonstrate how more efficiency and hence the increase in saleable material could be achieved.
Demonstration machine line-up:
With a trial in place it was also agreed that Molson Green could hold a VIP COVID compliant demonstration for a selected number of guests.
Four machines were supplied for the trial, a Terex Ecotec TSS 390 Single-Shaft Slow-Speed Shredder, a Terex Ecotec TSS 620T Trommel, a Doppstadt GT 130A De-Stoner and a Sennebogen 821E Material Handler. All these machines being available through Molson Green.
For the purpose of the trial the Terex Ecotec TSS 390 Shredder was fed green waste by the Sennebogen 821E Material Handler.
Processing in excess of 63tph green waste is shredded into a course material which in the full production process would then be put into windrows where it rots into compost.
After that process, the material is then put through an existing on-site trommel, taking out the fines then passing through an existing star screen which aggravates it further, taking out more fines and some lights.
This 8-60mm material (pre-processed) for the demonstration is then loaded by the 821E Material Handler into the Terex Ecotec TSS 620T Trommel which then screens out any -10mm saleable fines via a side conveyor. The oversize - clean organic and stone (up to 40% of the total mass) is then fed at a steady rate into the de-stoner immediately at the back end of the hopper
