Although throwaway nappies are undoubtedly convenient, these mostly-synthetic items cause never-ending steams of waste that will take centuries to disappear.
The Italian processor says that the recycled plastic can be used to make school desks and playground equipment. The cellulose can become viscose fabric or specialty paper, and the absorbent polymers could become gardening and flood barriers.
Disposable diaper waste has become a mounting environmental problem in the U. An estimated 3. Environmental Protection Agency. Fater says it has received backing from governments, consumers and other companies that have been galvanized by the world's growing plastic pollution problem. Due to European Union regulations, the company is not allowed to sell its products until it can prove there's a market for it. However, to that end, Fater claims it has secured letters of intent from multiple bioplastic manufacturers and paper mills.
It aims to recycle all of its "absorbent hygiene products" which include diapers, feminine hygiene products and incontinence pads, in at least 10 cities by The company also has a long-term goal to make percent of its products and packaging from renewable and recycled materials. About Contact Us. For those reasons, many modern parents wonder if single-use diapers are biodegradable, and what the most sustainable options are for diapering a baby. Read on for everything you need to know about how diapers should be disposed of, what eco-friendly alternatives exist, and more.
Unfortunately, conventional single-use diapers are not biodegradable. When something is biodegradable, that means it is made from nature, and is able to break down naturally and turn back into soil. Single-use diapers are typically made from a variety of plastic-based ingredients, and plastic is not biodegradable. And considering the fact that disposable diapers only hit the mass market in , according to Mother Jones , not enough time has passed to know exactly how long diapers and other plastic products really take to break down.
Diapers cannot be recycled, and must be disposed of in the trash. The only plastics that can go in your curbside recycling bin are rigid plastics, like bottles and containers. If you buy diapers in a cardboard box, that can be recycled with paper and cardboard; if your diapers come in plastic shrink wrap, check with your local grocery store if you can recycle it there with plastic bags.
A popular alternative to conventional single-use diapers is single-use biodegradable or compostable diapers. In general, diapers marketed as biodegradable or compostable tend to use more sustainable materials and production methods than regular diapers, making them a bit more eco-friendly. But if they are not actually sent to a composting facility, then their impact is only very slightly better than regular diapers.
But in reality, most single-use diapers contain plastic, meaning they will wind up in the same place as your average Huggies — the landfill.
The world biodegradable gets tossed around a lot when talking about eco-friendly diapers. This helps make consumers feel like those diapers will break down in the landfill, when in fact, these diapers all use plastic and will not break down for hundreds of years. That said, some of these companies do take extra steps to make their diapers a little less terrible for the Earth before they hit the landfill; for example, by using some biodegradable materials, sustainably-harvested wood pulp, and keeping them free of chlorine and fragrance.
Most diapers marketed as either biodegradable or eco-friendly cannot be composted, because they include various synthetic components.
However, there are a few single-use diapers on the market that can be composted — typically, only in commercial or industrial compost settings, and not in home or backyard compost bins. These results were published in the scientific journal H2O. No other processing method other than incineration has shown a similar level of degradation.
To the extent that traces of pharmaceuticals are still present after the TPH process, it is included in the refined slurry and then broken down in the sludge fermentation step of the water purification process. This can be considered as the final step in the pharmaceutical degradation process. Absorption granules SAP are broken down in the TDH reactor and settle in the fermenter and the water purification plant as magnesium salts.
Composting tests have been conducted to obtain an understanding of the ecotoxicity levels. A toxicity study was conducted on the compost using watercress, barley and earthworms, in accordance with the applicable standards. The results show that the material is safe, and has no harmful effects on the environment. Can ARN B. At the moment, there is no cause for concern about the long-term technical and financial continuity of ARN B.
Its order portfolio is sufficiently full. Rivierenland Water Authority provides it with purification sludge after it has been fermented. As TPH is an extra, and not absolutely necessary, step in the process, there will always be sufficient capacity available. If both incineration lines are deactivated by a defect or maintenance work, then the TPH will be shut down temporarily. In that case, baby diapers and incontinence briefs will be incinerated and purification sludge will be fermented as normal.
What if fewer diapers or less sludge is delivered than expected? The installation can only process a fraction of the volume of baby diapers and incontinence briefs available in the Netherlands. As a result, the supply is expected to exceed the processing capacity for the foreseeable future.
The installation can already process all of the RWZI sludge from the Nijmegen facility, but this sludge will be partially replaced by baby diapers and incontinence briefs. The business case is based on a conservative prognosis. Furthermore, in addition to the calculated risks, the business case also offers sufficient opportunities and alternatives to optimise the scale. What is the diaper composition? In the recycling process, it is important that the majority of used diapers consists of urine and faeces.
Since , the proportion of paper pulp has declined and the proportion of plastics has slightly increased. Faeces, urine, paper pulp and SAP are processed together into the refined slurry and fermented.
This percentage can be reclaimed in the future, and the plan includes this process as a possible optimisation step. Healthcare becoming more sustainable is a fact, the components of baby and incontinence diapers are subject to change. In the meantime, there are already diapers on the market that no longer contain any cellulose eg Drylock. Fossil components such as plastic and SAP have a biobased alternative. We think those components are gonna be used in the future. By being able to handle those components, our technology is future proof.
An additional mLCA in which we tested biobased diapers within our reactor shows that our environmental performance is even better with those components. EBI holds the patents and will market the processing method and the reactor. Tests have indicated that this method works best when the diapers are treated together with sewage purification sludge. This may sound strange, but in fact the contents of a diaper are no different from the composition of sewage treatment sludge. That is why the Rivierenland Water Authority has been involved in the application of the technique.
The added value of this technique is that pathogens and pharmaceutical compounds are almost completely destroyed in the process. Construction has begun on a single reactor, and if it functions as expected, the installation will be expanded with two additional reactors. Combined, the reactors will be able to process 27, tonnes per year. After years of testing on pilot scale ARN started in the first of three reactors on commercial scale.
We learned a lot, changed things and made improvements. Now the result is the decision to install two additional full scale reactors. With this stap the first full-scale plant for diaper recycling is a fact. From the diapers we produce biogas, bio granulate, artificial fertilizer and plastics. The project is executed in close cooperation with the Waterboard Waterschap Rivierenland.
The technology can also handle biobased diapers in which fossil plastics are replaced by PLA. This places a landmark for the future aiming at design for recycle and a biobased economy. This makes additional CO2-savings possible for the future. We expect the increased capacity will be fully operational in July Read the article NL. Collecting diapers separately and then recycling them instead of incinerating them with residual waste is on the rise again. Read the report.
SGS Search has carried out a review of the environmental analysis CE-Delft report of our diaper recycling method on behalf of the Dutch government. Conclusion: "There is no reason for doubt about the conclusions in the report , including: CO2- footprint: replacing the current conventional method by the TDH method results in a climate gain of kg CO2-eq per ton of diaper material processed in the current situation.
More than a year we tested with a pilot installation. This removes pathogens and drugs. The products biogas, biomass and plastics are created from the diapers. The entire chain has been included in the comparison; from collection to finished products. June Read the note. Elsinga noted during the mLCA study that a diaper manufacturer is replacing the plastics in diapers with polylactic acid PLA.
