Liquid Waste Disposal & Collection Services

If your business produces liquid waste, you can’t just pour it away or leave it sitting in the wrong container. It needs to be stored safely, collected properly, and sent to the right treatment or disposal site. Under the Environmental Protection Act 1990, businesses have a Duty of Care to ensure liquid waste is stored safely and collected by a registered carrier.

We arrange liquid waste disposal, collection, removal and recycling for businesses across the UK. Our service includes free bins and containers, scheduled or on-demand collections, and Duty of Care documentation for every job.

Liquid waste management process

  1. Tell us about your liquid waste

    Tell us what liquid waste you’ve got, how much you produce, and how often it needs collecting. We’ll price the collection from there.

  2. Free Container Delivery

    We deliver IBCs, drums, or barrels to your site, with no hire, rental, or delivery fees. You only pay for collection.

  3. Fill & Secure

    Liquid waste should be stored in suitable tanks, drums, IBCs, interceptors, or sealed containers before collection. We can help arrange the right collection method for your waste type, site access, and volume.

  4. Scheduled Collections

    Your waste is taken for treatment, recovery or disposal, and you’ll get the paperwork for the collection.

What is liquid waste?

Liquid waste is any commercial waste with a high liquid content, including wastewater, oils, chemicals, grease, sludge, sewage, contaminated water, and other fluids produced by business activity.

Types of liquid waste we collect:

Liquid waste covers a broad range of materials produced by businesses across every sector, including:

Wastewater and trade effluent: Process water, rinse water, and trade effluent from food production, manufacturing, catering, and commercial laundries. Trade effluent discharged to sewers requires consent from your water company under the Water Industry Act 1991.

Grease trap and interceptor waste: Fat, oil, and grease (FOG) collected from grease traps and oil interceptors in restaurants, food manufacturers, and petrol stations. Grease traps require regular emptying to prevent blockages and comply with drainage agreements.

Liquid food waste: Brewery waste, dairy effluent, juice and beverage production residues, and other organic liquid waste streams from the food and drink industry.

Waste oil and hydrocarbon liquids: Used cooking oil, motor oil, hydraulic fluid, and other hydrocarbon liquids. These may be eligible for recycling or energy recovery rather than disposal. We’ll let you know what collection route is suitable, including recycling or recovery where that’s available.

Chemical process liquids: Industrial process liquids, laboratory liquid waste, and chemical wash-down waters. Hazardous chemical liquids require specialist disposal with consignment note documentation.

Sewage and septic tank waste: Liquid waste from septic tanks, cesspools, and holding tanks at properties not connected to mains sewer.

Liquid waste recycling and recovery

Where possible, liquid waste is sent for recycling or recovery rather than straight disposal.

  • Waste cooking oil and used vegetable oil can be refined into biodiesel or used for energy recovery.
  • Certain industrial solvents and process liquids can be recovered through distillation and reused.
  • Organic liquid food waste can be processed through anaerobic digestion (AD) to generate biogas and biofertiliser.

We’ll always identify the appropriate recovery route for your liquid waste stream. This can reduce disposal costs and gives you clearer records for internal reporting.

Liquid waste FAQs

  • bin shapes icon What is liquid waste?

    Liquid waste includes any liquid material produced as a by-product of business activities that requires disposal, treatment, or recycling. This includes wastewater, trade effluent, waste oil, liquid food waste, process chemicals, grease trap waste, interceptor waste, and septic tank waste.

    In the UK, liquid waste that is classified as hazardous (due to its chemical composition, toxicity, or other hazardous properties) must be handled under the Hazardous Waste Regulations 2005.

  • bin shapes icon How is liquid waste disposed of?

    It depends on the type of liquid. Common methods include:

    • Dewatering: separating solids for recycling
    • Treatment: removing contaminants from wastewater
    • Incineration: for hazardous chemicals and acids
    • Composting: for liquid food waste
    • Recycling/reuse: e.g., processed waste oil

    Liquid waste should not be poured down drains, put on land or mixed with general waste unless you have the right permission, such as trade effluent consent.

  • bin shapes icon What regulations apply to liquid waste?

    Businesses must comply with:

    • Environmental Protection Act 1990
    • Duty of Care Regulations
    • Hazardous Waste Regulations (where applicable)
    • Water Industry Act (prohibiting unlicensed discharge)

    You must store liquid waste securely, use licensed carriers, and keep duty-of-care documentation.

  • bin shapes icon Where should liquid waste be disposed of?

    Liquid waste must go to an authorised treatment facility. You cannot:

    • Pour liquids into drains
    • Pour oils onto land
    • Put liquids into standard general waste bins

    We collect your liquid waste and deliver it to the correct facility for secure treatment, recovery, or disposal.

  • bin shapes icon Can liquid waste go down the drain?

    No. Businesses should not pour liquid waste, oils, chemicals, sludge, or contaminated water down drains unless they have the correct permission and treatment process in place.

    Business Waste Ltd can arrange compliant liquid waste collection and disposal through licensed carriers, helping you avoid pollution risks, blocked drains, and duty of care issues.

  • bin shapes icon How often should grease traps be emptied?

    Grease traps should be emptied when they reach 25% capacity with fat, oil, and grease. For most commercial kitchens, this means monthly or quarterly emptying, depending on cooking volume and trap size. Under drainage agreements and FOG (fats, oils, greases) regulations, businesses are responsible for maintaining their grease trap and ensuring accumulated waste is disposed of by a licensed carrier.

    Business Waste arranges regular grease trap emptying for restaurants, hotels, schools, and food manufacturers across the UK.
