Micropollutants Remediation Recovers Energy
Micropollutants remediation is one of the most important challenges at our days. The widespread application of sewage sludge endangers the environment just because of their presence. As biosolids, many chemicals, like antibiotics, hormones, drugs and PCP (personal care products), can enter the food chain thus exposing many people to their harmful effects.
Micropollutants remediation as a threat
Until now, the remediation of micropollutants has been largely underestimated. In fact, they belong to the category of so-called “emerging contaminants”. In the last years more scientists and some governments began to focus their attention on micropollutants.
This is very important, because despite the common belief, they are so dangerous to the health. Different chemicals may cause different effects to the individual health. However, they all are “endocrine disruptors”.
Depending on specific types of micropollutants, another important threat to the environment and public health deserves our greatest attention: drug resistance.
It’s a very serious problem and this worrisome trend is constantly increasing. So, it’s mandatory to avoid the presence of drugs and similar products into the environment. This is the only way to counter effects of drug resistance. And endocrine adverse effects as well.
Prior of talking about what are solutions to address this issue, we must focus the attention on sources that release such chemicals into the environment. Soil and water are equally important.
Sewage water treatment plants are the major source. Due to their physical and chemical properties, micropollutants pass through common filters. So, they concentrate in resulting sludge. Then this sludge is applied to crop fields as a fertilizer (because rich of precious nutrients).
Despite being treated before the application, biosolids still remain inside the sludge. So, the final effect is the direct exposure of crops and their human consumers to such dangerous micropollutants.
Micropollutants remediation from a new perspective
Many people and scientists agree on a ban for sludge application in agriculture. On the contrary, many farmers disagree with them. In fact, despite its load of harmful chemicals, sludge brings many benefits to crop fields. The high concentration of valuable nutrients is the most relevant one.
If farmers don’t apply this sludge, they must buy nutrients on the market. This would lead to a significant increase in costs (and in prices too). As we can see, this case is very important. We have to consider reasons of economy and compare it to the ones of the environment and public health.
Until now, this has been the only opportunity to solve the issue. Costly, not well accepted by farmers and especially not sustainable for agriculture. However, since a few years, we can count on a new, very good, opportunity.
We decided to create a deep training on how to do that. You can find the full training by clicking this link. In short, it’s now possible to transform sludge into a valuable source for natural energy (biogas), in order to make it even more convenient than before. But that’s not all.
In fact, wile recovering energy from this composting-like treatment, we also can recover the most precious nutrients. So, agriculture will still benefit from their application. At the end of the process, the final product (treated sludge) may be sent to building industries.
By doing so, at least three different industry sectors will benefit from this treatment. Environment will be much safer and public health in turn.
Micropollutants remediation with natural tools
What makes the proposed solution really great is the addition of only two natural products to the common treatment. We are talking about a normal “composting – like” treatment, which however needs two additives for the achievement of our desired goal.
Such natural additives are: a special mushroom and a substrate. The mushroom is widespread, so there are no issues for collecting it. The same is valid for the substrate.
Mushrooms grow on their substrate, then sludge and grown mushrooms generate a mixture. After the right amount of time, the composting – like treatment generates energy and the final product allows to recover nutrients for the agriculture.
There are some other possibly effective natural treatments for such a serious environmental issue. However, this one currently is the most convenient, not to mention the opportunity to help immediately at least three different industrial activities (definitely not bad, at our challenging times).
Remedial Energy dedicates a special attention to micropollutants and you even can request some special trainings or highly targeted handbooks on them.
This issue is really challenging and cases may differ a lot from each other.
That’s why we must act now.
