Waste analysis and classification

Identifying types of waste (dry, wet, special, recycled)

This service includes a field visit and detailed study of the food production process in order to prepare a waste separation matrix based on the source of production (preparation, cooking, serving, storage areas). Wet waste includes fruit and vegetable peels, food scraps, coffee and tea grounds; dry waste includes cardboard, plastic, glass and metal cans; and special waste includes burnt oils, solid fats, detergents and packaging contaminated with chemicals.

Estimating the volume and physical composition of waste

In this service, the amount of waste generated is calculated in kilograms per day and cubic meters per day based on the production capacity (number of meals), the menu offered, and the amount of process waste. The percentage composition of each category (e.g. 60% wet, 30% recycled dry, 10% special) is determined. Seasonal changes and peak hours of waste generation are also predicted.

Determining legal and environmental requirements

This service includes a thorough review of national environmental, municipal and EPA regulations regarding industrial kitchen waste disposal. Requirements regarding organic matter limits, waste oils, effluent discharges and distance of waste stations from food preparation areas are documented. Required certifications such as ISO 14001 are also included in the design.

Design of internal collection and transportation system

Design of separation and temporary storage stations
This service includes the placement of color-coded waste separation stations at key points in production (behind the preparation line, next to the washing sinks, near the packaging machines). Each station has separate containers with hygienic lids, clear labels and standard colored bags (green = wet, blue = dry, red = special). The capacity of each station is determined based on the volume of waste generated in a work shift.
Designing internal waste transportation routes
In this service, dedicated, one-way routes are designed for the movement of wheelbarrows or waste containers from the separation stations to the central collection room. These routes are separated from the production lines, food storage and serving hall and have uneven flooring, appropriate slope and intermediate washing points. The design includes a clear passage (at least 120 cm) and local ventilation points.
Selection and placement of tanks, balers and compactors
This service includes determining the technical specifications and positioning of the main waste management equipment in the central collection room. For dry waste (cardboard, plastic), a horizontal baler with a compression force of at least 30 tons is selected. For wet waste, a sanitary compactor with an automatic discharge system and washing capability is considered. Temporary storage tanks are designed with an appropriate volume (e.g. 1100 liters) and equipped with an automatic closing system and a discharge valve.

Designing reduction, recycling and disposal processes

Design of a crushing and dewatering system for wet waste
This service includes the design of a wet waste processing line including a grinder with stainless steel blades and a volume reduction capacity of 80%, followed by a dewatering device with centrifugal force or screw press. The output solid mass with a moisture content of less than 20% is suitable for use in compost or conversion into animal feed (in compliance with veterinary regulations). The separated water is directed to the wastewater pretreatment system.
Design of a dry waste recycling line (paper, plastic, metal)
In this service, the design of a manual or semi-automatic separation station is carried out for the separation of paper and cardboard, polyethylene, polypropylene, PET, aluminum and metal cans. The baler for each batch is separate. The dust collection and ventilation system is designed to prevent the emission of suspended particles and odors. Sufficient space is provided for the storage of compressed bales (each bale about 400 kg) until delivery to recycling centers.
Design of a special waste disposal system (burnt oils, chemicals)
This service includes the design of double-walled steel tanks with an appropriate capacity (e.g. 1000 liters) for storing used cooking oils. The tanks are equipped with a drain valve, level gauge, breather valve with activated carbon filter and a leakage collection pan. For chemicals (used cleaning solutions, paints, solvents), special HDPE containers with a hazard warning label are considered. All special waste is delivered under contract with environmentally trusted companies and delivery documentation is kept for 5 years.

final output

Delivery of a complete set of separation station location maps, internal transportation route maps, waste volume and composition calculation booklet, technical specifications of equipment (baler, compactor, shredder, tanks), standard operating procedures (SOP) for separation, transportation, and disposal, and registration and reporting forms to regulatory authorities.
