Types of kitchen waste

Kitchen waste refers to unconsumed food and leftover raw materials that generally get thrown back into the food supply chain and landfills. Around 28% of greenhouse gas emissions originate from food systems, according to FAO. Food waste and food loss both have a significant impact on climate change as waste that decomposes in landfills produces greenhouse gases, mainly methane.

There is a growing awareness of sustainable methods to manage kitchen waste, which has opened up an entire industry for recycling such kitchen waste into good compost and fertilizer.

Waste management is a critical issue, especially in urban areas, and has given rise to a lot of new technologies and machinery that can transform food waste into compost, fertilizer, or energy in the form of biogas.

Using a kitchen waste machine can reduce kitchen waste and make a small but positive impact on the environment. The compost produced can be used in gardens or given away to people in need of good organic fertilizer.

Kitchen waste machines can be broadly categorized into the following types:

• Composters: Kitchen waste composting machines are designed to accelerate the natural decomposition process of food scraps into compost. They typically use micro-organisms, bacteria, and enzymes to break down organic waste. Kitchen waste composting machines vary in size, features, and processing times. Some machines can produce compost in a matter of days, while others take weeks or months. Most composting machines offer odourless processing and do not attract pests.
• Biogas Generators: Kitchen waste biogas machines are specialized systems that convert organic food waste into biogas (a renewable energy source primarily composed of methane) through a process called anaerobic digestion. In this process, microorganisms break down the organic matter in the absence of oxygen, producing biogas as a byproduct. Kitchen waste biogas generators come in various designs and capacities, suitable for both domestic and industrial use. They save the cost of solid waste management and sewage treatment. The biogas produced is clean energy that can be used to reduce dependence on fossil fuels and boost energy security.
• Pulverizers/Shreaders: Kitchen waste pulverizers shred food waste into smaller pieces to speed up the decomposition process. These machines can handle various types of organic waste, including fruit and vegetable peels, stems, leaves, and other kitchen scraps. Kitchen waste shredders vary in size and capacity. Smaller units are suitable for household use, while larger industrial-grade shredders are designed for commercial kitchens, restaurants, and food processing facilities. The processed material is then fed into other machines that convert the waste into compost or biogas.
• Odor Control Systems: These systems are crucial in food waste processing facilities, composting sites, and anaerobic digestion plants. They help minimize unpleasant smells and retain air quality in and around the waste processing unit. Such waste disposal systems use filters, carbon scrubbers, or bio-filters to neutralize harmful gases before releasing them into the atmosphere.
• Separators: Kitchen waste separators are used to segregate food waste from non-biodegradable waste. For instance, plastic food containers and other packaging are separated from the organic material to ensure that only compostable material is treated further to convert it into compost or biogas.
• Pre-treatment Units: Pre-treatment units refer to any process or method to process food waste before it undergoes further treatment to convert it into compost or biogas. Such treatment includes crushing, grinding, shredding, or adding enzymes or bacteria to accelerate the decomposition process.
• Insinkerators: An insinkerator disposes of food waste right at the source under running water, as it is known to create organic matter. It is a preferred way to deal with food waste in municipal solid waste management systems, as it reduces the volume of waste that needs to be processed elsewhere.

Specifications and Maintenance

Some crucial specifications of a kitchen waste shredder include its material, voltage, power, noise level, capacity, and applicable kitchen types.

• Applicable kitchens: Not all kitchen waste shredders fit the kitchens where they are placed. As a result, knowing the kitchen type helps choose a suitable shredder. The most common kitchen waste disposal units are designed for domestic and commercial kitchens. However, the kitchen waste shredder for the home may also suit other small-scale kitchens, including community and institutional ones.
• Capacity: Kitchen waste disposers shred food waste into different levels of fineness. Some models offer an option to grind waste finer or coarser. Shredding food waste to a finer level increases the disposal unit's capacity and reduces clogs in the piping system. Knowing the level of waste a disposal unit handles can also help choose a suitable model for a particular application.
• Noise level: Noise levels from kitchen waste disposal shredders are measured in decibels. Lowering waste at the source can emit a noise level between 10,000 and 20,000 RPM. This may be suitable for domestic kitchens but not for commercial ones. Commercial-grade disposal shredders tend to be louder because they have more powerful motors.
• Power: Motors in kitchen waste shredders are rated in horsepower and determine how fast and efficiently waste is ground. Domestic waste shredders have 1/3 to 1/2 HP motors that can handle typical food wastes. Commercial waste shredders have motors rated between 1 HP and 5 HP because they have to handle more exceptional waste and be in continuous use.
• Voltage: Voltage requirements for kitchen waste shredders depend on the type and size of motor used. Domestic shredders typically work at 120 V and can connect to standard home outlets. Some commercial or industrial shredders may operate at 240 V to provide enough power for larger motors.
• Material: Grind rings and blades in stainless-steel-framed shredders bury food waste and push the material through the sieve in a pulverized state. Some shredders come with a sieve made of plastic, which is an affordable alternative to those with metal sieves. Kitchen waste disposal units are made of corrosion-resistant stainless steel. This makes them less susceptible to rust, improving their average lifespan and allowing businesses and homes to use them for many years.

It is easy to maintain a kitchen waste shredder. Most have self-cleaning disposal systems that flush waste with water, cleaning the grinding chamber. Regular flushing prevents clogging of inlets and outlets. Other disposal units have pressure nozzles that can blow out waste lodged in hard-to-reach areas. Some disposers have removable hoppers that make it easier to reach and clean sections of the disposal unit. Regular removal of the hopper for flushing reduces the risk of infection and bad odors.

Usage scenarios for kitchen waste prices

Due to the ever-increasing demand for waste management and recycling services across various sectors worldwide, these waste prices are witnessing a strong surge in demand in many industries.

According to a report, the global organic waste to energy market was valued at USD 54.49 billion in 2021 and is expected to reach USD 58.03 billion by 2024, growing at a CAGR of 2.44% during the 2021-2024 period. These numbers indicate a consistent growth in the use of kitchen waste management machinery that transforms waste into useable energy and organic fertilizers. As the world moves towards a greener planet, more and more industries will make use of machines for processing their kitchens waste effortlessly and efficiently.

Due to this strong growth rate, garbage disposal machines offer a wide range usage scenarios across numerous industries.

Restaurants, hotels, and cafeterias generate tons of organic waste daily in the form of food scraps, peels, leftovers, and packaging material. Commercial food waste disposers are fitted under kitchen sinks to process smaller volumes, while industrial disposers with higher capacities are installed near food processing units. This not only results in reduced waste sent to landfills but also minimizes the carbon footprint of these establishments. The organic waste sinkers convert the organic matter into nutrient-rich compost or biogas, which can be utilized within the premises or sold for external use.

Residential complexes and multi-dwelling units face similar challenges when it comes to managing food waste generated by numerous households. Centralized food waste disposers or decentralized unit-based systems can help tackle this issue efficiently while promoting responsible waste disposal practices among residents.

Institutional kitchens such as those found in schools, universities, hospitals, and catering services also produce significant amounts of food scraps on a daily basis. Implementing food waste shredders into these kitchen facilities can greatly reduce the volume of organic waste produced while simultaneously reducing odour and pest problems associated with discarded food scraps.

Supermarkets, grocery stores, and convenience stores generate substantial amounts of organic waste from unsold perishable items, expired products, and food preparation activities. Installing onsite food waste processing machines can help these retailers mitigate their environmental impact by minimizing the amount of organic waste sent to landfills. Instead, they can convert this waste into valuable resources like compost or biogas right at the source.

Food processing facilities such as meat plants, dairies, breweries, bakeries, and fruit & vegetable processing units are major contributors to the generation of organic waste at an industrial scale. These facilities produce large volumes of food scraps that are often high in moisture content. Hence, installing large capacity processing units in these facilities helps manage this issue efficiently.

How to Choose Kitchen Waste Price

Comparing kitchen waste prices will become much simpler if buyers know what to look for when shopping for a kitchen waste disposer. First of all, it will help if buyers familiarize themselves with the features and specifications of the kitchen waste disposer model they are interested in. This includes the motor's wattage, the overall size and capacity of the unit, operational noise levels, installation requirements, and the type of kitchen waste it is designed to handle.

When it comes to pricing, the more advanced a model's features, the higher the price. Buyers will have to decide what features are essential to their kitchen and what are merely desirable but not necessary. For example, the noise level of a kitchen waste disposer is something most people are particular about because it can get quite noisy, especially when grinding hard substances. Waste disposers with a quieter operational noise level tend to have a more powerful motor but come at a higher price. If this is a feature a buyer wants to provide to future customers, they will likely choose a more expensive model.

Waste segregation is a vital part of waste disposal, and not all disposers are equipped with that feature. Models that are designed to separate waste while it's being processed come at a higher price. Many customers may not be aware of the importance of grinding capacity or waste segregation and will settle for a standard disposer. This is, of course, subjective, and buyers will have to do extensive research to find out what potential customers prefer and what they're willing to spend to give them the best experience.

Another important factor that comes into play when determining prices is the installation difficulty. If an installation manual is provided, buyers may opt for a particular model they think will be easy to install and, therefore, cost-effective. But if the installation process seems too complicated, they may choose a model they're familiar with and have to spend on the installation costs. This will obviously add to the kitchen waste disposal unit's end price.
