Lean manufacturing waste includes wasted material, avoidable downtime, inaccurate matching of resources to tasks, unproductive activities, and overproduction. Manufacturing defects and operator errors can also cause waste. Planned downtime is preferred to reduce personnel costs, while unplanned downtime results in more waste. Unproductive activities can involve unnecessary movement or tasks not part of the production […]
Ethanol waste, or still grains, is a co-product of the dry milling process used to produce ethanol from corn. It is sold as a feed supplement for livestock, containing nutrients three times higher than the original corn input. It is particularly valuable as a high protein and energy supplement for cattle, poultry, and pigs. Ethanol, […]
Proper disposal of chemical waste is important to avoid harm to the environment and human and animal health. Guidelines vary globally, but in the US, the EPA maintains lists of hazardous waste. Hazardous waste collection programs are available to ensure safe disposal. Containers should be compatible with waste, labeled, and rinsed before disposal. Special consideration […]
Chemical waste from manufacturing plants, labs, and households may be hazardous and requires proper handling and disposal. Legislation varies internationally, with the US and UK having specific regulations. Improper disposal poses risks to the environment and people. Specialized disposal services are used, with most waste incinerated or treated chemically before being disposed of in a […]
A waste heat recovery boiler recycles energy from a process to create steam, reducing fossil fuel consumption and greenhouse gas emissions. There are two types: fire-tube and water-tube boilers. Water-tube boilers can handle higher pressures and respond quickly to heat input. Waste heat boilers can be used in cogeneration plants to improve efficiency. A heat […]
Medical waste is created by healthcare facilities, research facilities, and pharmaceutical companies. It is divided into four categories: infectious, radioactive, hazardous, and general waste. Infectious waste must be managed and contained to avoid the spread of infections. Disposal is governed by the Resource Conservation and Recovery Act and is typically done through incineration or landfilling, […]
Pharmaceutical waste, including unused medications and personal care products, poses a threat to human and environmental health. It requires special treatment and cannot be disposed of like conventional waste. Poorly managed waste could end up in the hands of people who abuse drugs. Sharps and other supplies can also contain hazards. Wastewater treatment plants are […]
Hazardous waste management involves proper containment, management, and disposal of hazardous waste, which can pose risks to the environment and public health. Reduction of hazardous waste and public education are important aspects, and laws are enforced by public health inspectors and police. Hazardous waste management is an area of the waste management field concerned with […]
Waste management systems deal with waste materials through techniques like collection, transport, recycling, disposal, or treatment. Waste types include human, industrial, hazardous, and biodegradable waste. Waste management systems vary by social, cultural, and technological norms, and can be preventive or reactive. Hazardous waste requires specific waste management systems based on potential hazards. A waste management […]
Plastic waste management involves recycling plastic to reduce environmental contamination and production costs. Industries collect and recycle plastic waste, with some outsourcing to waste management companies. Regulations must be followed to ensure environmentally friendly and safe practices. Plastic waste management is a collective term for various approaches and strategies used to recycle plastic materials that […]
Waste management involves collecting and treating human waste, while recycling transforms waste into reusable materials. Different types of waste are handled differently, with landfills and incineration being common methods. Recycling reduces the environmental impact of waste, but critics argue its disadvantages. Improved waste management and recycling methods will lead to a more efficient world. The […]
Around half of all food produced globally is wasted, with consumers in developed countries throwing away 30-50% of perishable foods. This waste occurs at all levels of production and results in the loss of resources. Meanwhile, 1 in 9 people worldwide lack sufficient food for a healthy life. Considering that 1 in 9 people on […]
Waste management consultants ensure safe, legal, and efficient disposal of hazardous and non-hazardous waste. They design waste management systems, specialize in different types of waste, and evaluate existing systems. They also determine the safest means of transporting, storing, and disposing of nuclear and hazardous waste. Waste management consultants must have strong communication and computer skills, […]
Separate collection involves sorting waste into categories for different purposes, such as composting, recycling, or energy generation. This can be done manually or with machinery, and is often incentivized by companies and governments. Examples include city bins and facilities for large-scale waste separation. Just as the name seems to suggest, separate collection is a procedure […]
Over a third of the world’s food produced for human consumption is wasted, with over 200 million tons wasted by consumers in rich countries, equivalent to the net food production of sub-Saharan Africa. Food waste occurs at all levels, with buy-one-get-one-free sales being a major source of waste. More than a third of the world’s […]
One third of global food is wasted, with 62 million tons in the US alone. Companies are upcycling food waste into new products, such as Misfit Juicery’s juice made from defective produce and Toast Ale made from surplus bread. Consumers are willing to buy and pay more for these products. A third of all food […]
Good waste solutions require thoughtful planning and implementation, with a focus on eliminating or reusing waste. Education on the effects of waste and global efforts are important. Incentives and consequences may be necessary. The best solutions reduce waste and convert it into something beneficial. There are at least two components generally required for a waste […]
A waste autoclave sterilizes and reduces the volume of waste materials on site, eliminating the need for off-site processing. The device uses heat, steam, and pressure to kill pathogens and can operate in batch or continuous modes. Proper loading and periodic testing are necessary for effective sterilization. A waste autoclave is a device that processes […]
Waste from water treatment includes biological waste, industrial water waste, and household waste. It is sent to a wastewater treatment plant to filter solids and release clean water. Industrial wastewater may be treated on-site before being transported to a government plant. Waste from water treatment is any product that is discarded into a sewage system, […]
Waste management services handle different types of waste, including residential and hazardous waste, and offer services such as landfill management and recycling. Some waste requires special disposal methods, and reusable items are sorted and sent to facilities for new products. Waste management services are companies or agencies that deal with unwanted materials. There are numerous […]
