Used Diapers Turned into New Ones Thanks to Super-Recycling Japanese Towns and New Innovation

In the 1990s, a pair of Japanese municipalities estimated that the landfill they shared was going to be full by 2004.

Unless they did something to start reducing the size of their waste streams, the towns would have to sacrifice more precious land, or truck their waste much farther afield to another site.

Their response was to ramp up recycling of the clearest categories such as glass, paper, and metals, before moving on to more complicated streams, particularly a very stinky one: dirty diapers.

“Ultimately, our top priority is to reduce our trash and extend the life of the landfill,” Kenichi Matsunaga, an environment official for the city of Shibushi, told the Japan Times.

Billions of diapers—used by the very youngest and the oldest in society, are discarded every year in Japan. Made of layered, super-absorbing fibers and other materials, they aren’t readily recyclable.

Located in Kagoshima Prefecture, a new recycling initiative for diapers separates and shreds this core material in a way that prepares it for reuse while saving millions of tons of landfill-bound waste.

Shibushi, and the nearby town of Osaki, recycle 80% of household waste—some four-times the national avergae. Here, the company Unicharm aimed to pioneer its diaper recycling method where locals are already used to sorting their trash.

Residents’ diapers are collected, but only if their names are written on the bags to ensure accountability. Then, they’re washed and shredded until their component elements of plastic, pulp, and super-absorbent polymer (SAP) are separated.

Previously, GNN has reported that the company has used this material to make toilet paper, but now have advanced their method and machinery enough to reuse the pulp in diaper manufacturing.

The process uses ozone, a sterilizing gas, to clean and deodorize the pulp to the point that it passes sanitary requirements. The company is currently working on ways to prepare the SAP for reuse, and expects progress by 2028.

The country is probably the only one in the world where more diapers are produced for incontinent elders than for babies. Larger and more robust, they take up more space in landfills.Japan wants to aim for 100 cities and towns to be recycling diapers by 2030, “or at least to start talking about it” reports Japan Times.

Worried about feeding your baby solid foods? Here’s what you should know

Lillian Krikheli, La Trobe University and Samantha Turner, La Trobe University

When you have a baby, mealtimes can be messy and stressful.

If you’re a new parent you may be unsure what, when, and how to feed your little one. And you may also worry about choking, particularly when it’s time to start feeding your baby solid foods.

For babies starting solids at the recommended age of six months, it’s important to offer foods in a variety of different ways. Purees can be a helpful starting point, but they shouldn’t be the only texture a baby experiences.

Research suggests not waiting too long to introduce lumpy or textured foods. Infants who start eating lumps at 10 months or later were more likely to develop feeding difficulties and become selective eaters.

So if you’re a parent, where do you start? And what other foods are good to try?

Why texture matters

Mealtimes are crucial for a child’s development because they’re an opportunity to explore different textures and develop oral motor skills.

Imagine you’re eating a piece of toast. This involves performing a range of movements including holding, biting, chewing and swallowing. All of these actions require different muscles to work together, and only improve through practice. But that practice is only effective if it involves real food, as opposed to non-edible teething toys and isolated oral exercises like jaw opening and closing or cheek puffing.

When starting solid foods, many parents rely on purees and pouches as convenient ways to feed their babies. There’s nothing wrong with puree in itself. Many of our favourite foods resemble purees. Think of buttery mashed potato, yogurt, ricotta and applesauce.

The problem arises when purees and pouches become the only texture parents offer their babies, particularly early on. Babies who only eat pureed foods have less opportunity to develop the skills needed for eating and drinking. And research suggests children who frequently eat pouched foods are more likely to become fussy eaters.

So there’s nothing inherently bad about pureed foods. But feeding your baby varied foods gives them more opportunity to develop crucial oral motor skills.

Does it matter how I feed my baby?

There are various ways to start giving your baby solid foods.

One common approach is “baby-led weaning”. That’s where parents encourage their baby to feed themselves, rather than fully spoon-feeding them. This can encourage your baby to be more independent and explore food on their own. But it may also make mealtimes messier and more time-consuming for parents. And it can also feel daunting for parents who are concerned about choking.

However, one 2016 study found babies who feed themselves are no more likely to choke than babies who are spoon-fed. Foods which are suitable for baby-led weaning include strips of omelette, ripe avocado wedges or well-cooked corn on the cob. However, the researchers emphasised the importance of preparing foods appropriately and using risk minimisation strategies. These include avoiding high-risk foods such as popcorn, cutting round foods such as grapes and cherry tomatoes, and supervising babies whenever they eat.

An ‘in-between’ option for feeding is to offer your baby purees, while giving them a degree of independence. For example, you may pre-load a spoon for your baby to bring to their own mouth. You can also pair purees with larger foods, say a broccoli floret dipped in hummus. These combinations will help your baby develop eating skills while you become more confident with feeding your baby.

No matter what feeding approach you take, infant first aid training is a must for parents and carers. And if your child was born premature, has a developmental delay or has specific nutrition requirements, it’s best to speak to a paediatrician before giving them solid foods.

When you have a picky eater

Even if your baby transitions well to solid foods, toddlerhood can bring a new set of challenges.

Toddlers tend to be selective about what foods they do or don’t eat. They may also become more cautious around unfamiliar foods. These are both normal parts of a child’s development.

But problems can arise when parents pressure toddlers to eat food they don’t want to eat or when they aren’t hungry. Even small gestures, such as using a “spoon as aeroplane” or asking them to take “one more bite” in front of the TV or tablet, can put pressure on children. As a result your child may eat that next mouthful but, over time, they may develop a negative relationship with food and mealtimes.

As parents and carers, our role is to offer food at predictable times and in positive mealtime environments. Some ways to do that include:

  • trusting they’ll eat as much as they need
  • eating shared meals when possible
  • modelling enjoyment of different foods during shared meals
  • offering new foods alongside familiar favourites
  • giving children multiple opportunities to see and try new foods, even if they don’t eat them the first time.

Unfortunately, babies and toddlers won’t love every meal you make them. But in time they’ll come to learn about, and even enjoy, a world of different textures and tastes.The Conversation
