Reducing waste

Follow these top tips to start reducing the waste your business produces.

Tips for the office | Tips for the factory

• Segregate your paper and cardboard for recycling.  Improve the amounts of materials collected by having fewer general waste bins and more recycling collection points.
• Purchase in bulk where possible.  This uses less packaging and means you will need less deliveries.
• Encourage your suppliers to use returnable packaging systems.  This will reduce their cost in the long run and reduce your waste bill.
• Ensure that you are receiving the right quantities of the materials you are buying.  It is best to rigorously check both quantity and weight.
• Create set procedures for goods receiving and handling.  This can help minimise product and material damage.
• Do all you can to reduce material residues in packaging.  For example would it be useful to use drum warmers to reduce viscosity or wash out IBCs to obtain more material yield? How about a bag splitter / shaker for dry materials?
• Replace hazardous materials with less harmful alternatives.   Many solvent-based materials can often be replaced by water-based or high solids materials for example.
• Consider buying recycled materials.  Look at recovered solvents and oils, or plastics and other solid materials with recycled content.
• Do all you can to reduce spillages and evaporative losses around the site.  For example, pipe materials around site to processes rather than move them in open containers and decant. Ensure your storage vessels and reservoirs are fully encapsulated to avoid losses.
• Improve product design or production planning to reduce material wastage.  For example could you make a small change in the product to allow improved material yield? Could you look more carefully at batch sequencing to reduce wastage and the need for cleaning?
• Try to prevent or reduce ‘start-up’ wastage.  For example on production lines or printing presses.
• Consider improving process controls to reduce wastage.  Sensors, for example, can be used to detect critical process and product changes, avoiding wastage.
• Think about switching to processes and equipments that naturally produce less waste.  For example, could materials be mixed centrally and accurately in a properly controlled and calibrated system rather than using bucket chemistry at the side of the process? Could ultrasonic cleaning be used with water-based cleaners to avoid solvent degreasing?
• Carry out planned preventative maintenance and checking/ calibration of your plant.  This ensures that equipment is functioning properly and efficiently.
• Review how you package your products.  Could you use less materials or layers, or materials that are easier to recycle at the customer site?
• Improve the efficiency of packaging ‘fill’, and pallet and vehicle loading.  Often too much air is distributed, leaving space in boxes which could be better used.
• Reuse supplied packaging.  For example, machines are available that can lattice cardboard boxes to make a useful, bulky fill material.
• See if waste streams can be further segregated for on-site reuse.  For example can excess materials (extruder waste, powder coating etc) be kept clean enough to be put back into the process? Can line ‘pigging’ be used to recover product from pipelines?
• Segregate materials more effectively to improve recycling.  Search for local recyclers able to take your waste, and talk to other nearby companies about having joint recycling collections.
• Use compactors, balers, drum, can and glass crushers etc.  Use to obtain revenue from recyclate or to reduce general waste costs.
• Segregate all hazardous waste.  Include segregating electrical items like fluorescent tubes and computer monitors, from general waste
• Do you use dedicated storage tanks for deliveries?  Where possible put bulk tanker deliveries into large dedicated storage tanks rather than receiving materials in smaller litre drums or intermediate bulk containers (IBCs)
