Why waste management


Courtesy of MERCODOR GmbH Sondermaschinenbau KG

Since 1973 we are a part of environmentally friendly and economical shredding systems for all types of waste.

Since 1973 MERCODOR GmbH Sondermaschinenbau KG (Special Products), Frankfurt/Main, The company’s shredding systems are used for the reduction of waste volume in various commercial and industrial applications, including hotels, hospitals, commercial kitchens and cruise ships, together with the removal of domestic waste and the recycling of raw materials. With the right customised equipment for the job, reductions in waste of up to 80 percent are achievable. With this reduction in volume, transport, storage and dumping costs are substantially decreased.

Environmental policy:

An environmental policy clearly defines the level and objectives to which to operate. It also ensures compliance with mandatory regulations and continuous improvement of performance.

Collection and separation:

There should preferably be strategically located waste handling stations for sorting different waste fractions, which are subsequently delivered to a garbage handling room for processing.

Onboard processing:

Food and galley waste can be collected, treated and stored in separate closed systems. Compactors, shredders and crushers can reduce the volume of the dry waste, which in turn reduces the storage space required.

Onboard storage:

The waste should be stored in a manner which avoids health and safety hazards. It is recommended that food waste and food contaminated waste are kept separate from the other garbage.


Recycling is preferred to disposal as recycled waste reduces cost for disposal and is a valuable resource. All disposal of waste at sea is regulated by IMO regulations and local regulations.

Dry waste handling on support and special vessels

On PSVs, AHTSs, MPVs, CSVs, seismic vessels, windmill installation vessels and research vessels, a large amount of space can be saved and waste disposal costs substantially reduced by means of a modern dry waste handling system.

The waste is separated into fractions onboard and its volume reduced by up to 90% by shredding and compaction.

Food waste on rigs and platforms

On fixed platforms an efficient food and galley waste handling system will eliminate the need to transport some food waste and enable controlled, hygienic and easy handling.

Food waste is collected and ground where it is produced. Thus the work for the crew is minimized and proper hygiene is maintained in the galley. If the rig is more than 12 nautical miles from land and the food waste is ground to
Merchant vessels

Merchant ships of all types, ranging from small feeder ships to car carriers, giant container vessels and oil tankers, travel the oceans daily transporting a vast range of cargoes.

Sea transportation is a fiercely competitive business. To remain profitable, shipowners and operators focus continuously on reducing operating costs. Uncertainty in the global economy, credit crises, fluctuating freight rates and oil prices all affect the ship owner’s profit margins. Bunker fuel oil alone can account for up to 60% of a vessel’s operating costs.

An important factor is the need to comply with increasingly stringent international and local environmental regulations, such as those relating to emissions and ship-generated waste.

Ships produce a huge variety of solid and liquid waste streams, dry waste, food and galley waste and others. All the waste needs to be processed – initially onboard and later on shore. Waste handling in compliance with the regulations must be made easy for the crew by means of clear procedures for sorting the waste into fractions and user-friendly solutions for reducing its volume.

International and local regulations

Waste handling onboard ships is clearly regulated. IMO sets the international standards and defines special regulated areas. Individual nations or groups of nations have their own regulations..

In addition to international and local regulations are individual port regulations. When it comes to landing and disposal of waste, every country and every port has different requirements, facilities and cost structures.

Cargo owners turning to ‘green’ shippers

Environmental awareness is growing among the public in many industrialized countries. This, in turn, is motivating an increasing number of cargo owners around the world to examine not just the environmental aspects of their own products but the entire life cycle of the products, including sea transport.

This leads many cargo owners to give preference to shipping companies making documented efforts to minimize the environmental impact of their operations.

Dry waste and food waste

Important factors relating to dry waste and food and galley waste are the ship’s operating profile. the number of people onboard, length of time between port calls, waste reception facilities at ports visited, and amount of storage space available onboard.

A ship operating on regular routes, calling at the same ports can establish efficient waste handling routines more easily than a ship that operates on the spot market and that may visit different countries and ports on almost every voyage.

In a modern waste management system, dry waste is separated into fractions onboard the ship to allow for recycling, and the volume is reduced by crushing, compaction and shredding. This reduces transportation and disposal costs.

Food waste is collected, ground where it is produced and discharges into the sea where permitted. Thus the work for the crew is minimized and proper hygiene is maintained in the galley.
