Recycling of plastic bottles

Recycling plastic bottles is a fundamental process within modern industrial waste management.

The bottles are generally made of high-density polyethylene (HDPE), a highly recyclable material. Through appropriate industrial processes, this waste can be transformed into reusable granules for the manufacture of new products.

Recycling bottles reduces landfill waste and transforms bulky waste into a valuable raw material, becoming a profitable and sustainable solution.

As recycle plastic bottles in industrial plants

Recycling plastic bottles requires a structured technical process that ensures the proper transformation of the waste into reusable raw material. The main objective is to fragment, clean, and granulate the plastic to obtain a homogeneous raw material suitable for new production cycles.

The process for recycling bottles usually includes the following phases:

Reception and classification

Separating the bottles by type of material and level of contamination.

Initial crushing and granulation

Reducing the size of the packaging to facilitate handling and obtaining reusable plastic flakes or granules.

Washing and waste disposal

Especially important when recycling detergent bottles or chemical products.

Drying and conditioning

Preparing the material for industrial reuse.

Crushing and granulating process of bottles

Recycling of water bottles and industrial drums

The fragmentation process of the bottles into smaller pieces transforms the bulky containers into a processable and reusable material. This material is then granulated to produce homogeneous flakes or granules. This step is essential to ensure:

This represents a key opportunity in the management of large-capacity plastic containers. This process is especially relevant when dealing with containers that have held chemicals or industrial products. The proper treatment of these containers includes:

Uniformity in recycled material

Reducing the volume of waste and facilitating feeding to the next stages.

Greater washing efficiency

Maximizing the quality of recycled material.

Manufacturing of new products

Better conditions for its reuse in new production processes.

Reduce losses during treatment

The maximum amount of material is recovered for reuse.

Classification by type of material

And by the level of contamination of the bottle or jerrycan.

Crushing and size reduction

To facilitate processing in the subsequent stages of recycling.

Intensive wash

To remove any remaining liquids or stuck-on residue.

Plastic granulation

For industrial reuse and to extend the material's useful life.

Types of recyclable bottles and its applications

Recycling plastic bottles allows for the recovery of high-value materials, provided the different types of containers and their composition are correctly identified. Proper sorting is essential to optimize the process and guarantee the quality of the recycled plastic.

Below, we detail the main types of recyclable containers and their possible uses after treatment:

Bottles of detergent and chemicals

Reuse and recovery of plastic bottles

Recover HDPE quality after proper washing.

Reduce the environmental impact of potentially contaminated packaging.

Generate recycled granules suitable for non-food technical uses.

Production of new non-food packaging.

Industrial components and technical parts.

Agricultural products and elements of urban furniture or containers.

Mills - granulators

They allow for obtaining uniform flakes or granules, essential to ensure the quality of recycled plastic. Controlled granulometry improves washing efficiency and facilitates the reuse of the material in new production processes.

Pre-crushers for bottles

They allow for the reduction of the size of full-size bottles before further processing. They operate at low speed and high torque, ensuring controlled fragmentation without overloading downstream equipment.

Industrial crushers

They achieve a more precise reduction of the material, generating homogeneous fragments that facilitate subsequent granulation and washing. These machines are designed to work with high-strength plastics, even when recycling detergent bottles with residue still attached.

Washing and conditioning system

In the recycling of containers that have held liquids or chemicals, washing is a critical step. It removes impurities, labels, and product residue, ensuring a clean material suitable for reuse.

Conveyor belts

Conveyor belts and feeding systems ensure a continuous flow of material between the different stages of the process. Proper automation reduces downtime, improves productivity, and minimizes manual handling of waste.

Complete lines for recycling bottles

We manufacture complete lines that integrate crushing, granulation, washing, and conveying into a continuous and optimized system. These lines are custom-developed, adapting to the production capacity and available space of each plant.
