35% Solid Content is Ideal for Composting

If you are mulling over the possibility of composting solid organics, please do  check with any composting authority such as the Composting Association of the UK, Cornell University, or the US Composting Council.  There you will learn that the ideal dry matter content for successful composting of any organic material  is 35%.   If, in your operation, the dry matter is lower, you will also find an abundance of information about suitable amendments and much, much more.   Good information is at hand, so seek it out.  It goes with out saying, if XACT can be of any help, please feel free to give us a shout.  Many thanks.  D

Compost the Residue From Anaerobic Digester

If you compost the residue from the anaerobic digestion process with XACT’s BioReactor, then you will be extracting all the value from the waste.  After all, isn’t that what we are going for?  The extraction of methane and generation of electricity is great as far as it goes, but there is tremendous value still remaining in the waste from this process.  Taking advantage of this value is easy with the composter by XACT.  The resulting compost is bankable both from a commodity point of view and soil amendment point of view.

Compost made by the BioReactor is high quality therefore demanding a higher price than average.  Or, it replaces sand or sawdust as a bedding material therefore eliminating out-sourced bedding material.  Or, compost reconditions crop fields (with numerous benefits) so that fertilizer costs will be reduced.  So, please consider composting as the final stage of  the anaerobic digester process and reap ALL the benefits.  Leave nothing to waste!

Compost Massive Volumes of EFB With the XACT In-Vessel Rotating Drum Composter

The massive volumes of Empty Fruit Bundles (EFB) created in the processing of palm oil can be composted successfully creating high quality organic fertilizer.  This organic fertilizer can then be applied back onto the soil at the plantation.  Because this organic fertilizer is an excellent soil amendment and very beneficial for plant growth, the need for commercial fertilizers is eliminated.  Given the tremendous costs of fertilizer, the cost saving is significant.  The elimination of the expense of commercial fertilizers goes straight to your bottom line, and within very short order, the payback on the XACT BioReactor is realized.  Please do investigate our website www.xactsystemscomposting.com for more information and we would welcome any questions you may have.  Many thanks….Doreen

What Amendments for Composting Would You Use?

Here at XACT Systems, we are regularly asked about amendments for composting organic waste.  Will I need them?  What will I use?  How much will I use?  You get the picture.

The short answer is…it depends (not useful information).  The long answer is that amendments are required when the C:N ratio of the waste itself is not close to the ideal ratio of 25:1.  When this is the case, which amendment to use and how much is calculated using the C:N ratio of the amendment in conjunction with that of the waste.   The website of Cornell University Composting website is an excellent resource in general and specifically has an index of a multitude of amendments and their typical characteristics (originally developed by the Natural Resource, Agriculture, and Engineering Services ).  Or save yourself some time, and let me send you this Table as a PDF.

Just as important from a business stand point, the amendment you most want to use is the one where it costs you nothing to obtain it, or better yet, one that you are being paid to dispose of for a 3rd party.

Please feel free to contact me if you would like to discuss your particular composting challenges and how the in-vessel rotating BioReactor by XACT can serve your purposes.  XACT Systems is dedicated to helping you acheive a SUCCESSFUL trouble-free, neighborhood-friendly composting process.

Many thanks.  D

In-Vessel Rotating Drum Composter Converts Food Waste to Compost

This in-vessel rotating drum composter is composting food waste, and interestingly enough, the amendment being used in horse manure.  The operators of this facility know that in order to get good quality compost out, they need to put the right blend of feedstocks in.  The constraints of the blend consists of:  1) a proper percentage of moisture and  2)  the correct proportion of Carbon to Nitrogen.  Because the food waste stream on its own did not meet these constraints, there would need to be an amendment added to the food waste.  The horse manure was available and also needed to be disposed of, so this composting facility determined the right blend of these 2 waste streams, and are now indeed, producing very good compost.  No less than a triple win!

This BioReactor is composting food waste.
