Canadian-built bioreactor composting food and garden waste at 8,000-room resort in Cancun, Mexico

Ontario-based XACT Systems recently installed a BioReactor Composting System at a resort in Cancun, Mexico to compost all of the site’s food and organic waste. The Cancun Palace Resort is home to 8,000 rooms, generates 2,500 tons of organic waste per year, and management needed to reduce their high waste haulage costs and landfill tipping fees. In addition, the resort wanted to take meaningful action to reduce their GHG emissions.

In-vessel system

The X-ACT In-vessel Compost-ing System is designed as a lower cost, cleaner, and more energy efficient way of managing waste, compared to a system using a windrow turner. The X-ACT system achieves total aerobic composting using a rotating (or tumbling) enclosed, vessel. It does not pollute the air or ground water, and produces no leachate or run-off that could pollute underground water tables. The composting drum on these units is turned by a low horsepower electric motor. A 10-foot diameter by 32-foot long drum, rotating 30 tons of manure, 10 times per hour, will do so using a 7.5-hp motor. Or, a bigger 10-foot diameter by 72-foot long drum uses only a 10-hp motor – turning 60 tons, 10 times per hour. Key features include: VOC and odour control; no problems with weather; easily maintained temperatures; and no problem with stress fractures, common with many traditional in-vessel systems. The vessel is constructed in eight-foot modules, and uses a centre drive with a low horsepower industrial eurodrive.

In-vessel system is low-cost, clean, efficient

The X-ACT In-vessel Composting System is designed as a lower cost, cleaner, and more energy efficient way of managing waste. The X-ACT system does not pollute the air or ground water, and produces no leachate or run-off that could pollute underground water tables. The composting drum on these units is turned by a surprisingly low horsepower electric motor. For example; a 10-foot diameter by 32-foot long drum, rotating 30 tons of manure, 10 times per hour, will do so using a 7.5 hp motor. Or, a bigger 10-foot diameter by 72-foot long drum uses only a 10 hp motor – turning 60 tons, 10 times per hour. Compared to the energy requirements of a windrow turner doing exactly the same number of turns, these systems require a much lower amount, contribute positively to surrounding soil and vegetation, and there are far less toxic emissions, according to the manufacturer. Additionally, because these systems offer virtually complete aerobic biodegredation, are fully enclosed and feature negative exhaust and a biofiltersystem, there is no odour To accomplish total aerobic compost-ing, the X-ACT system uses a rotating (or tumbling) enclosed, vessel designed to create the ideal environment for the aerobic bacteria to thrive. If these vessels are housed in a building (which is not necessary because of the insulation encapsulating the vessel) any VOC’s or odours from the building are actually sucked into the vessel, thus cleaning the air in the building itself.
