What is in a good design?

A pair of shoes are made up of many parts.

There are:

-the uppers
-the linings
-the soles
-insoles as cushion for the feet

As such, there are many different kind of material required to make a pair. Material used in making shoes are:

-leather
-textiles
-rubber
-synthetics materials like polyurethane (PU)
-foam

On top of that, there are various types of footwear.  You can check out the types available in the market at the following link:

Different Types of Footwear and Their Names

Other than protecting the feet, they are also designed for:

-different activities.
-climates.
-occasions.

Feet generally stop growing when the growth plates in the bones fuse, which is typically:

-by age 14-16 for girls.
-by and 16-18 for boys.

Feet for some individuals can continue to grow until the early 20s. The number of pairs, school-age children, can go through in a year depends on:

-their activity level.
-how quickly their feet grow.
-the durability of the shoes worn.

People who can afford it may own many pairs of the same type of shoes and in different colours, even though they have not worn out or outgrown what they already own. According to an article I read, "10 Shoe Facts Everyone Should Know", on Shoeaholics, Celine Dion has over 10,000 pairs of shoes and one in eight people own over 100 pairs of shoes. 8.43% of people buy shoes because they make them feel good.

We may not be able to cut down on material for making shoes for those who are into following current trends in fashion but we can adopt Kenton Lee’s shoe design that he developed for children in developing countries. You can see from this video that the shoe is designed to last five years as its size can be altered as the child’s feet grow.

;

The design is very suitable for school-age children living in tropical countries. For normal activity, they can wear socks with the adjustable shoes to protect their feet. Their regular school shoes will last longer when they are only worn during athletic activities in school. However, in countries where there are four seasons, can thermal or thicker wool socks keep them warm during the colder months?

Let us also work on belts for school children. According to Size Guides from Your School Uniform, a child's waist line from age 6 to 14 years can be from 22" to 30". Based on a review shared by Sammy Lu about Willbond belts that she bought for her children, I think its concept is good as it has:

-a magnetic buckle which makes it easier for a child to put on and remove.
-an adjustable belt which is also elastic so that it is more comfortable to be worn over time, as the child grows.

Buying such adjustable shoes and belts for children will be cheaper if they are sold in the schools they are attending. It will also help reduce material wastage since children, as they grow, will not have to replace them as often compared to other regular shoes and belts sold in the market that are not adjustable.

This is something that parents can highlight during their Parent-Teacher Association meeting to make it happen.

Solution to plastic litters in the Philippines

According to a report by Greenpeace, Philippines is the third worst plastic polluter of oceans.

However, there is hope for change through a trash management programme developed by nonprofit, Mother Earth Foundation. The city council of San Fernando allows the poor to make a living by picking through trash from every house daily and bring it all to sell at one of its 35 waste warehouses throughout the city.

Through this new system, more than 75 percent of waste gets composted or recycled and it costs the city council about 80 percent less to manage waste, as trash trucks are no longer required to collect waste from every house.

To boost plastic recycling, Dutch designer, Dave Hakkens, provides free tutorial at Precious Plastic so that one can learn t build a machine that can shred up plastic waste so that the material can be used to make useful artifacts.



More money can be made from a finished product than from recycling, if the poor adopt this idea.

PET plastics eating bacterium

Good news!  


A team of scientists led by Dr Shosuke Yoshida from the Kyoto Institute of Technology in Japan, discovered a new bacterium with the ability to completely break down PET plastics in a relatively short space of time.

The scientists were able to recreate the bacterium, which has been named Ideonella sakaiensis, in the lab and have them break down the plastic to its basic building blocks: two environmentally harmless monomers called terephthalic acid and ethylene glycol.

And if you are wondering why should we care about this progress, it is obvious that you have not read about the "plastic soup" that Captain Charles Moore discovered at the North Pacific Subtropical Gyre,

Can we start a Zero Waste Community?

Can we start a Zero Waste Community in Malaysia?  If you are wondering what that is, this is how it is being done in USA.

Earth friendly with less



If your batteries are all mingled up and you do not know which are still good to use, there are battery testers in the market to help salvage them from the lot.  This is what I have.














Here is another way for you to test your battery life without any gadgets.  See if it works for you too.



Can we find ways that will help us reduce our reliance on "gadgets" and be more earth friendly?  A great activity to start working on for earth month, don't you agree?

Slim and well adorned? Clear them out!

Slim and well adorned.

That's what they are always eyeing.  To them the next one is always better with a lot more to play with! When will they stop groping for the next one that comes along?

Yeap!  Mobile phones! The latest model wins hands down again.

So, what did you do with the older models?

How about selling and donating part of the payment to a charitable organization?  Mark Bowles makes it possible for Americans to do just that with his ecoATM, as long as they are willing to have their license and thumb print scanned.  A great way to verify ownership and prevent sales of stolen mobile phones.

So, what do they do with the gadgets collected by ecoATM?  75 percent of the devices are sold to refurbishers while the rest go to e-waste recyclers.  What a great way to reduce e-waste and re-use what are still applicable.

OK, let's check out what this machine, which won the Popular Science's , “The Best of What’s New Award" in 2010, is all about.

Broken? Fix it and share.

Are you good at fixing things up? If you are, wouldn't it be great if you could share your expertise online? What for? Just imagine the number of devices you can save from ending up in the dumpsters earlier than it should. That should make you feel like a eco friendly hero, right?

Like that feeling? Then go to "Self-Repair Manifesto - iFixit" to see how you can join fellow heroes, build a free repair manual for broken devices.

Ka ching. Hear that too? Money can be saved! Before shopping for a replacement for that broken whatever, check out ifixit Manual to see if any heroes have posted a "how to fix it" guide. And if you can't find it, post the problems you have using your device. Your questions could well develop the next eco friendly hero at Self-Repair Manifesto, hero.

Yeah, right! You will make it to the hero list too.

Another Lantern for Mooncake Festival

I thought my son is too old for lanterns until he told me he wants one too after checking out the one I did for his sister.

So here is the model I created for him and it is made up of a cardboard box for a monitor.



It is obvious that I have been inspired by all the traditional stuff I saw during...


...my trip to Beijing.

Green brooms sweep clean

I just got back from a trip to Beijing and I noticed that the parks and places of interest I visited are very clean. How did they managed that? Nothing high tech. Just some sweepers with brooms they improvised from bamboo stick and branches.

Here is another version of a bamboo broom.

Bamboo plants don't grow in your country? There are alternatives.

Lantern for Mooncake Festival

We are celebrating the mooncake festival this Saturday and I have created a lantern for my little girl.


How much do I have to spend for materials? Nothing! It's made up of plastic bags that I have cut into strips to crochet into...

...granny squares...


...to decorate an empty container for cooking oil, with its top cut off.

Here is a closer view of the lantern.


May you have a wonderful time eating delicious mooncakes and drinking good tea by your lanterns.

The Pain. About relationships.

Is it silly to consider posting my contribution for The World's Best Presentation Contest 2009 here? After all, it is about relationships. So, what is "green" about sustaining relationships? Wait! Before you think that I greedy for votes to win this contest, listen me out.

Imagine setting up home for a family. Now imagine setting up home for the same family in two separate locations because mummy and daddy can't get along anymore. Talk about creating wastage and increase in energy usage, broken marriages and relationships are not going to help reduce them much. Don't you agree? So, here goes my slideshow on relationships. Reduce wastage, let us work on making relationships stick.



Yes to "In sickness and in health, living in the same house, till death do us part".

Plastic containers? Modify and re-use.

What does this empty ice cream tub has in common with the cooking oil container?



Their diameters are close in size. So what?

I cut the top off an empty oil container at the right height and I can store my less often use stuff. Then I placed the ice cream cover over its top, to prevent cockroaches or lizards from running all over and staining them. Got the picture?



They are also handy drawers for my kitchen shelves for storing my 3 in 1 packets drinks.



You have to be blind if you are not able to find your stuff with these modified containers.

Sand? Not for beaches only.

Children of my time are allowed to play with sand. We didn't have to wait till we were brought to a beach to start. We could find sand to play with in our gardens or in that of our neighbours'.

There was a lot of sand to play with in the compound surrounding our houses too. So, we didn't need paper or pen to express our creativity as we played and drew on the sand.

The houses that our children grow up in now are usually built close knit and all paved up. Most parents of today will be aghast if they caught their children playing with sand and with crime rate rising, they wouldn't encourage their children to play outdoor.

Maybe it is time for us to revive that interest again to reduce usage of paper. How? Let Ilana Yahav shows you with her sand art, "Let's Get Together".



Yes, one can make a living playing with sand! And don't forget that playing with sand can be therapeutic for children and adult. Sand play therapy has been used by therapists as an Emotional Literacy tool for personal development and as an aid for emotional healing.

Let's find a tray or build a pit and play sand with our kids.
