Use of Composting For Biosolids Management



There are lots of ways to treat biosolids, one of the simplest method is composting, which will create a marketable end product that will be easy to handle, store, and use for commercial and private management. The end product is a Class A, humus-like material without detectable levels of pathogens. This can be applied as a soil conditioner and fertilizer to gardens, food and feed crops, and rangelands.

When composting biosolids, the method provides large quantities of organic matter and nutrients such as nitrogen and potassium to the soil. It also improves soil texture and elevates soil cation exchange capacity, which could be seen in the soil’s ability to hold nutrients. These are all indicators of a good organic fertilizer.

Acceptance of biosolids compost by communities

Generally speaking, the public is a lot more accepting of biosolids that were treated through composting method because they are aware and familiar with composting. As you well know, composting can be done by households right in their very own gardens. By simply having a large and deep tub, residents can put in anything they can think of into the compost pile—from household waste to grass trimmings. As long as it is biodegradable (no plastics, please), it can go into the pile.

After a while, the result will be an organic matter that can be used to amend and fertilize the soil. The foul odor may throw you off guard, but this is only part of using organic materials instead of commercial-grade or chemical fertilizers. You would know by the smell of the fertilizers that they were made organically and not processed chemically or commercially.

The reason why some producers create biosolids through the use of composting method is because this has a high acceptability among stakeholders, beneficiaries, and the general public. This is then a good alternative to other bulk and bagged products that are being made available to homeowners, landscapers, farmers, and ranchers.

Biosolids are being sold only in bulk. They are not sold by portion or small bags, so there’s a long way for household owners to be able to get their hands on portioned biosolids. Most of the people who use this organic form do so because they are being applied on large garden areas that are also being utilized for business products. Home gardeners, on the other hand, have a hard time accessing biosolids because of its unavailability to be packed and sold in small quantities.
