Buyer's guides, process explainers and industry news for anyone specifying plastic recycling and extrusion equipment — how shredders, washing lines and pelletizing lines are configured around a given feedstock, and which plastics can realistically be recycled at scale.
16 Aug An extruder melts plastic and pushes it through a die, but what comes out depends on the die and the equipment behind it. This guide covers the three screw zones, the main parts, the types of extruders, and why a recycling extruder and a pipe extruder are built for opposite problems even when both run the same material.

16 Aug Whether plastic wrap is recyclable depends entirely on which wrap is meant. Kitchen cling film is one of the few plastics with essentially no recycling route, while industrial pallet stretch wrap is clean single-resin LLDPE baled at source and one of the more valuable film feedstocks a recycler can buy. This article separates the two materials, explains the two distinct ways film defeats sorting equipment, sets out the four properties that make warehouse stretch film a premium feedstock, and lists what actually causes a wrap load to be rejected.

15 Aug Plastic bags are recyclable as a material but almost never through a kerbside bin, and the two answers are about different things. This article separates the polymer from the collection system, explains why a bag behaves differently from a bottle of the same resin, what a loose bag does to disc screens and near-infrared sorters inside a material recovery facility, how a film washing line processes baled bags into dry flake, why densifying is a stage rather than an accessory, and where printing ink and multilayer laminates set the ceiling on the pellet grade.

15 Aug A crusher is a wear machine — the purchase is one payment and the blades, screens and bearings are payments you keep making, which is why buying on purchase price alone gets it wrong. This guide covers the six checks specific to size reduction equipment: blade steel grade and heat treatment with the regrind count that follows from it, rotor shaft and bearing selection with housings outboard of the cutting chamber, whether the welded frame was stress relieved before machining, how long a screen change actually takes, whether the acoustic enclosure and dust extraction sit inside the quoted price, and what to measure when the supplier runs your own scrap.

15 Aug Search for plastic recycling machine manufacturers and you get dozens of companies whose websites are close to interchangeable. Some own a workshop, some own a sales office and a supplier list. This guide covers the ten checks that tell them apart — who physically builds the line, whether the certificates resolve to a public register, whether the machine will be test-run on your own material, how the technical conversation goes before a price appears, and how long wear parts stay available.

14 Aug Un negocio de reciclaje de plástico gana su margen en cinco lugares concretos — el diferencial de compra, el rendimiento, la mezcla de grados que puede certificar, las horas que la línea realmente opera y qué tan barato salen sus residuos del sitio. Este artículo recorre cada uno con cifras publicadas de las líneas de lavado y peletizado de SUHUI, y explica por qué cuatro de los cinco son disciplinas operativas y no condiciones de mercado.

14 Aug Que el reciclaje de plástico sea rentable es el resultado de cuatro cifras y no una propiedad de la industria. Dos pertenecen a su mercado y dos salen del equipo. Este artículo entrega las cifras publicadas de energía, agua y mano de obra que hay detrás del costo de conversión por tonelada, una hoja de cálculo de punto de equilibrio con las filas que dependen del mercado en blanco para que usted las complete, las variables que más mueven la respuesta y las situaciones en las que las cuentas simplemente no dan.
