Industrial waste management and liquid waste disposal methods that are safe and effective

Industrial processes invariably generate waste, be it general waste, hazardous waste, non-hazardous waste, biodegradable waste, food scrap, or potentially harmful materials. Proper disposal of industrial waste should be ensured, as its improper disposal will result in adverse impacts on the environment and human health. Pollution prevention (P2) should be the focus area of any industrial waste management strategy, which will help not only in preventing environmental contamination but also alleviate the concerns around global industrial waste, including liquid waste disposal. Pollution prevention involves the use of processes, practices and materials that minimise the creation of pollutants and waste, and reduce the overall environmental risk.   


Source reduction is the first step of any industrial waste management plan that aims to reduce the amount of waste produced and liquid waste disposal before recycling, treating, and disposal. Technological upgrades can help in reducing waste, and the use of alternate materials can result in less waste generation, which is less risky. Effective inventory control and having a clean and organised facility will also be helpful in waste reduction.   

  

Dealing with hazardous liquid waste   

Hazardous waste can be tricky to handle, as waste from these substances can have an immediate effect on the health of humans and animals. A substance is categorised as hazardous if it displays any of the four primary characteristics of toxicity, reactivity, ignitability, and corrosivity. Immediate toxicity is readily apparent as it affects living beings shortly after being exposed while slow toxicity is difficult to determine as its effects may not be seen for years. Certain toxic waste, known as carcinogenic, can cause cancer and biological changes in individuals exposed to them. Reactive materials like gasoline, gunpowder, and paint thinners are capable of spontaneous combustion during storage. Corrosive waste like acid can destroy materials and living tissues with chemical reactions.   

  

Reducing waste generation   

Optimising processes so that less waste is produced can help reduce waste generation. Specialised industrial waste management companies in Australia, such as Richmond Waste, not only emphasise waste reduction but also its recycling, treatment, and safe disposal. Metals such as aluminium, steel, and copper are valuable even in waste form and can be recycled for use in other business processes. Plastic and glass can be recycled and repurposed for use in other applications. Similarly, asphalt, rubble, and metal scrap from construction & demolition (C&D) activities can be used in other applications.   

  

Waste to energy (WtE) solutions   

If some sort of waste cannot be treated then the team at Richmond Waste will make use of alternative waste disposal methods, such as landfilling at a site that is designed to accept industrial waste. Burnable industrial waste can be put into incinerators that not only reduce the volume of waste but also produce heat that can be converted into energy. Household waste, food waste, wood waste and garden waste can be easily biodegraded. Composting is similar to biodegradation. It results in the reduction of waste and also produces natural fertiliser for plants.    


Treatment of wastewater  

Wastewater is one of the biggest components of many industrial activities, such as manufacturing, textile, pharmaceuticals, etc. Liquid waste disposal should be done appropriately as delaying it would not only harm water bodies but also result in a breach of regulations. Ensure that you dispose of your liquid waste appropriately. If you are not sure how to deal with your facility’s liquid waste while remaining compliant in Lismore, the Northern Rivers, Richmond Valley council area, and Far North Coast NSW, Richmond Waste can help you with customised liquid waste disposal solutions.  

  

Specialised bins and containers to store liquid waste   

Whatever the size of your business, or the type and amount of liquid waste you generate, Richmond Waste has trained crew to deal with your liquid waste disposal challenges. The company also provides specialised bins and containers to temporarily store any liquid waste at your facility. Richmond Waste utilises a variety of safe liquid waste disposal methods as part of its overall industrial waste management solutions. Dewatering is a common liquid waste disposal method wherein water from the liquid waste is removed until only solid waste remains. Solid waste is then disposed of while liquid water is recycled and reused.   

  

Sedimentation method for liquid waste disposal is employed for non-hazardous liquid waste. This simple method doesn’t require any high-end equipment as it makes use of gravity to separate solid waste from the liquid. Water left after sedimentation can be reused while solid waste can be safely disposed of. In solidification, liquid waste is turned into solid by adding bulking agents, such as fly ash, lime dust, or sawdust. The bioremediation method converts hazardous liquid waste into non-hazardous with the help of environment-friendly microbes. Root zoning is primarily used for residential liquid waste disposal that uses both biological and physical processes for treating liquid waste

A Look at Waste Services That Help Businesses in Waste Management

Image
       Businesses contribute to waste generation worldwide as we remain far away from zero waste generation facilities. Even the transition from manual to digital documentation has not mitigated the pace of waste production, largely due to the limited lifespan and disposal requirements of electronic devices. Instead of opting for cost-saving but unethical practices, businesses should engage waste management companies to address their waste responsibly.   The environment and safety of various life forms are more important than saving money as the actions taken for monetary benefits take a toll on the entire planet with issues like global warming and pollution on a steep rise. The problem becomes even more complicated because of the different types of waste generated by a company that might require multiple methods for safe disposal. For example, a company serving food at a location would definitely produce food waste but also require grease waste removal from time to time. In this a

Improving Commercial Waste Management for a Sustainable Future

Image
Even though we continue to take all our tools and technologies to greater heights continuously thanks to the consistent advancement in various sciences, sustainability remains out of our reach for now due to a combination of unethical practices and overreliance on the environment. Decades of negligence have also played a huge role, as for a long time, both residential, commercial, and industrial waste has been disposed of improperly without consideration for nature. Lastly, the slow adaptation of reducing, recycling, and reusing waste hasn’t been up to the mark.       Commercial Waste Management: A Necessary Implementation for All Businesses    The years of negligence related to waste management have led to an increase in various problems worldwide including global pollution and natural resource depletion. This is why every business needs to take their environmental duties seriously and get in touch with professionals for commercial bin service. Unethical practices like dumping i

Construction waste management and skip bin hire services to help you control the costs of your projects

Waste production is inevitable in any construction and demolition (C&D) project. These activities can have a major negative influence on the environment, as not only it is produced in bulk but may also include hazardous substances. It may include inert waste that is non-reactive, and does not decompose, like concrete, soil, and asphalt. Hazardous waste in the C&D waste may be in the form of chemicals, solvents, lead-based paints, and aesbestos, while non-hazardous waste in it may include the waste that does not damage the environment or human health immediately, like wood, cardboard, glass, and metals. The focus of any construction waste management strategy is to minimise the amount of materials going to landfills. It also helps redirect recyclable and recovered resources back to the manufacturing process.      Any construction waste management plan should also include the materials to be salvaged or recycled, materials handling requirements, and how the plan will be commu
