Does composting release CO2?

Does composting release CO2? Carbon dioxide (CO2) emissions from the composting mass are classified as biogenic. This means the same amount of gas is emitted during decomposition whether the organic material is composted or degrades in a natural setting.  Therefore, these emissions are considered carbon-neutral. Compared to waste management alternatives, it’s the best of the […]

Commercial vs. industrial composting: are they the same?

Commercial vs. industrial composting:  are they the same?  Commercial vs. industrial composting — no, they are not the same, though the terms may be used interchangeably on the web.  But one word has to do with the money trail and the type of organization that owns the facility.  The other is linked to operational scale and/or manufacturing approach.  A government-owned […]

Topic: healthy soil – compost feeds soil

Compost is soil’s superhero Sure, compost adds nutrients. But that might be this soil amendment’s least important function.  Quite often, articles will mention compost as a replacement for some or all of the nutrients that might be provided to plants through applications of synthetic (man-made) fertilizers.    That’s certainly true.  Compost delivers the macronutrients nitrogen, phosphorus, and potassium (NPK), plus a slew of plant-essential […]

Topic: healthy soil – use compost to manage stormwater

Comparing costs per gallon retained  Soil amendment is one of the least expensive ways to collect and manage stormwater  “Manage water where it falls.”  This sound advice is the foundation of the Milwaukee Metropolitan Sewerage District’s Regional Green Infrastructure Plan, a program that identified soil amendment as one of the least expensive ways to manage stormwater.  At 28 cents per gallon, improving soil is […]

Topic: Urban organics recycling – food waste mandates

Food waste mandates are only the halfway mark  Compost use gets organics recycling to the finish line  Unlike a decade ago, when food waste mandates were few and far between, there is a flurry of activity these days focused on diverting food waste and other residential/commercial biodegradables from landfills and incineration.  From the U.S. to Italy to northern India, the movement toward more sustainable management of organic waste from households and businesses is real […]

Topic: industrial composting – making sense of research data for composting cost comparisons

Making sense of research data Evaluating organic waste management options and cost comparisons When personal expertise is lacking, people place their trust in experts to facilitate decisions about everything from home additions to medical care.  Governing boards are no different.  They rely on the knowledge of utility directors, staff engineers, and consultants to help them […]

Topic: industrial composting – 7 keys to successful composting

7 keys to successful composting Composting “done right” can be easy or difficult.  Easy if facility operators understand and manage according to a handful of scientific principles.  Difficult if they do not. The specific method in use or design of the physical plant may determine the level of difficulty and costs required to get it right, but […]

Topic: industrial composting — how does bioremediation work?

Organic waste offers up a feast to hungry microbes Even some toxins can be degraded while composting’s “bugs” chow down during bioremediation Unseen by the human eye, microbes are the soil’s equivalent of worker bees.  They are responsible for a slew of soil functions.  Without them, soils don’t work as they should. “Soil organisms decompose […]
