Composting Septic Sludge

Composting Septic Sludge Tests Prove Successful

Composting septic sludge in 5 days AND making compost that is pathogen free is possible with the BioReactor by XACT Systems Inc.   In this testing project, the septic sludge is combined with other materials in order to make a balanced recipe of organics with a C:N ratio in the ideal range (20:1 to 30:1).  This is the vital first step in composting solid organic waste quickly and making compost that is pathogen free.  The second step is to compost this proper mixture in the BioReactor which is an in vessel rotating drum composter.  The composter rotates slowly and constantly.  The rotation tumbles the waste material inside the drum and exposes all of the material to the ambient oxygen.  The aerobic bacteria which naturally reside in the organic waste will decompose it.  The fact that all the bacteria are getting all the oxygen they need to do a great job of breaking down the material means that the waste will compost quickly and with little or no odor.  The innovative features of this 5′ diameter x 10′ long BioReactor allow the temperatures of the composting process to hit temperatures of 145 degrees Fahrenheit  to 170 degrees Fahrenheit and maintain it there.  Once these high temperatures are achieved, the septic sludge is exposed to this heat for 72 hours (as per the protocol stated by the EPA standard for pathogen kill in a composting process). After 5 days, the compost is discharged and it looks and smells like dirt.  It will make an excellent soil amendment and be a valuable revenue stream for this composting operation.

When composting septic sludge at 170 degrees for 5 days, pathogen free compost is guaranteed.

Composting Septic Sludge is made easy in the BioReactor. The processing temperatures are running between 145 degrees and 170 degrees.

Food Waste Composted with the In-Vessel Composter by XACT

Composting Food Waste Generated by 8,000 Room Resort in Cancun

Food waste composting

Food waste from the kitchens and dining rooms is collected separately and taken to the on-site composter for fast composting.

Food waste composted with the in vessel composter by XACT is solving the organic waste problem of an 8,000 room hotel in Cancun, Mexico.  The Cancun Palace Resort generates 2500 tons of organic waste per year, and wanted/needed to reduce their high waste haulage costs and landfill tipping fees.  In addition, the hotel management wanted to take meaningful action to reduce their GHG emissions.

The Palace Resort was able to solve both objectives effectively by choosing the BioReactor by XACT Systems to compost their organic waste.    As an added bonus, the Cancun Palace Hotel’s corporate image is enhanced by their responsible waste management initiative.  Plus the benefits don’t stop there!  The Return On Investment (ROI) is only 18 months making the investment in the BioReactor Composting System a savvy decision in all respects.

Food Waste and Garden Waste are the Feedstocks

The BioReactor is composting food waste from the kitchens and dining rooms as well as green and brown gardening residue.  The waste is processed in the in-vessel composter for 5 days.  Upon discharge, the compost is pathogen-free, weed seed-free and virtually odorless.

Composting in the BioReactor Is Followed by Vermicomposting

Composting Food Waste

The BioReactor is 8′ diameter by 40′ long. The food waste, green and brown plant residue are composted in the vessel in 5 days.

The next step in the operation is for the compost to be placed in the worm bins for further decomposition.  Vermicompost is process of decomposition of organic waste using worms.  The castings (or worm manure) have a high saturation of water soluble nutrients (readily plant available) and makes an excellent organic fertilizer and soil conditioner.  The Cancun Palace Resort uses the castings in their own nursery, gardens, flower beds, and on the golf course.
