DRD dry cleaning machines in recycler use

In plas­tics recy­cling, around 95% of all frac­tions must first be cleaned before they can be fed into the fur­ther recy­cling and treat­ment process. There are var­i­ous options for the clean­ing process, and in many cas­es only wet wash­ing sys­tems are con­sid­ered. How­ev­er, there are many appli­ca­tions where alter­na­tive clean­ing process­es such as the DRD dry clean­ing process should be con­sid­ered in the design.

DRD dry clean­ing machines con­sume sig­nif­i­cant­ly less ener­gy and dry and clean plas­tic frac­tions in a sin­gle oper­a­tion. In com­bi­na­tion with wet wash­ing sys­tems, they can make for the per­fect clean­ing sys­tem for a wide range of con­t­a­m­i­nants. Find out how and where the DRD dry clean­er from MAS can be used in every­day recy­cling and the pos­si­bil­i­ties the com­bi­na­tion with wet wash­ing sys­tems offers.

 

Stand-alone solutions or in combination?

For wet clean­ing sys­tem own­ers, the DRD is the per­fect com­ple­ment to the upgrade for eco­nom­i­cal clean­ing and dry­ing. Water scarci­ty, high water recy­cling require­ments, and com­plex approval process­es for wet clean­ing sys­tems mean that more and more cus­tomers are dis­cov­er­ing MAS DRD dry clean­ers. The DRD also scores points for its effi­cient ener­gy con­sump­tion. For impu­ri­ties such as sand, water, dust, and soil, the DRD can be used as a pre-clean­ing stage to sig­nif­i­cant­ly reduce the load on the sub­se­quent wash­ing process.

The DRD dry clean­ing machine can there­fore also improve through­put, open­ing up fur­ther degrees of free­dom in the clean­ing of frac­tions to be recy­cled. MAS DRD dry clean­ers can be used in two basic ways with numer­ous gra­da­tions:

• • Stand-alone: A stand-alone MAS DRD dry clean­er, whether sin­gle-stage or mul­ti-stage, removes many basic con­t­a­m­i­nants with sig­nif­i­cant­ly low­er ener­gy con­sump­tion while dry­ing the frac­tions at the same time. For heavy soil­ing, pre-clean­ing with sieves is rec­om­mend­ed to achieve opti­mum results.

  • Wet wash­ing com­bi­na­tion: MAS dry clean­ers can be com­bined with all wet wash­ing sys­tems and can car­ry out pre-clean­ing and/or post-clean­ing In this way, all frac­tions are com­pre­hen­sive­ly washed, cleaned, and dried as ener­gy-effi­cient­ly as pos­si­ble and at the same time pre­pared for fur­ther pro­cess­ing, for exam­ple in a MAS twin-screw extrud­er.

 

Dry cleaning of big bags

Many inter­na­tion­al DRD ref­er­ence sys­tems tes­ti­fy to the ener­gy-sav­ing clean­ing of plas­tic frac­tions of all kinds. One long-stand­ing MAS cus­tomer spe­cial­izes in the clean­ing of big bags, which are often con­t­a­m­i­nat­ed with residues of cement, flour, soil, and grav­el. Here, mate­r­i­al flows are increas­ing­ly shift­ed to the MAS dry clean­ing machine, lead­ing to eco­nom­ic ben­e­fits.

When the big bags are heav­i­ly soiled, the MAS DRD dry clean­ing machine can cov­er the entire clean­ing require­ment while con­sum­ing sig­nif­i­cant­ly less ener­gy than a wet wash­ing sys­tem.

 

Artificial turf recycling with DRD support

Here, mate­r­i­al flows are increas­ing­ly shift­ed to the MAS dry clean­ing machine, lead­ing to eco­nom­ic ben­e­fits . There are count­less sports pitch­es around the world for soc­cer, bas­ket­ball, and field hock­ey with state-of-the-art arti­fi­cial turf. When arti­fi­cial turf is replaced or even com­plete­ly removed, the mate­r­i­al to be recy­cled is sent to a MAS cus­tomer. Sand from the sub­struc­ture and abra­sion and oth­er rub­ber par­ti­cles must be removed dur­ing the recy­cling process.

After the large impu­ri­ties have been removed by a sieve, a DRD dry clean­er pro­vides the basis for ener­gy-sav­ing clean­ing of the shred­ded arti­fi­cial turf, which can lat­er be returned to the recy­cling cycle.

 

Other possible applications for the DRD dry cleaner

MAS DRD dry clean­ing machines are becom­ing increas­ing­ly pop­u­lar, and are used by numer­ous cus­tomers world­wide . Oth­er areas of appli­ca­tion include:

• • Films: Regard­less of their size and com­po­si­tion, film residues are con­front­ed with a wide vari­ety of mate­ri­als. The DRD removes non-adhe­sive con­t­a­m­i­nants quick­ly, and with­out leav­ing any residue.

 

• • Cement sacks: While paper sacks are main­ly used in Europe, cement sacks in Africa and North Amer­i­ca are pri­mar­i­ly made of polypropy­lene. The dry clean­er from MAS sep­a­rates cement residues from PP frac­tions.

 

• • Hoses: Many irri­ga­tion hoses run under­ground. If they are recy­cled after being replaced, soil, among oth­er things, sticks to them. The DRD dry clean­er from MAS removes the soil from the shred­ded hose frac­tions by fric­tion.

 

• Non­wo­vens: High­ly mois­ture-absorbent prod­ucts such as non­wo­vens should nev­er be cleaned in a wet clean­ing sys­tem, as they do not dry out again. Geo­t­ex­tiles laid in the ground (e.g. weed fab­rics) are first giv­en a rough clean­ing using a sieve before the DRD takes over the ener­gy and resource-sav­ing fine-tun­ing.
