Ghanaian Entrepreneur Builds Affordable Houses from Recycled Plastics

The real estate market is booming in Accra.Luxury communities continue to spring up in prime locations across the Ghanian capital.Realtors say the boom in luxury properties is fueled by the changing demography and growing economic activities in the capital.I think it started off from the oil sector in the late 2000s when Ghana discovered oil.I would like to believe that there was almost like a gold rush to Ghana at the time,so a lot of developers decided this is the best time to position themselves.So, they capitalized on that by getting multiple acquisitions and started investing it.Ghanas growing economy is driving up migration to its cities,where many Ghanaians find themselves competing for decent and affordable accommodation.The 2021 population census revealed that Ghana needs about two million additional housing units to completely accommodate its 30.8 million people.The deficit that we are talking about is in the medium to lower income bracket, and we dont seem to be doing well in that area.The average estate developer is unable to meet the price point for this category of people.But whether people are living in luxury or affordable housing, they are also finding themselves facing a common problem:plastic pollution driven by population growth.But plastic houses may be a possible solution to both problems.Nelson Boateng is building houses made of bricks from recycled plastics and is doing so at a fraction of the cost of concrete buildings.His one-bedroom apartment costs 11,000 U.S. dollars and was made with 13,400 kilograms of plastic waste.We advanced in producing plastic Lego bricks to build affordable housing for the very low-income Ghanaian.Not because it is very cheap, the durability is less.It is stronger than the normal concrete bricks that we have because these bricks can withstand waterlogged areas;it can withstand earthquakes and it doesnt burn.

阿克拉的房地产市场正在蓬勃发展。豪华社区继续在加纳首都的黄金地段如雨后春笋般涌现。房地产经纪人说，首都不断变化的人口结构和不断增长的经济活动推动了豪华房地产的繁荣。我认为这始于21世纪初加纳发现石油时的石油业。我愿意相信当时几乎有一股淘金热涌向加纳，因此，许多开发人员认为现在是定位自己的最佳时机。因此，他们利用这一点进行了多次收购，并开始投资。加纳不断增长的经济正在推动向其城市的移民，在那里，许多加纳人发现自己在为体面和负担得起的住房而竞争。2021年的人口普查显示，加纳需要大约200万套额外的住房才能完全容纳其3080万人口。我们谈论的赤字属于中低收入阶层，我们在这一领域似乎做得不好。房地产开发商一般无法满足这类人的价位。但是，无论人们住的是豪宅还是保障房，他们都发现自己面临着一个共同的问题：人口增长造成的塑料污染。但塑料房屋可能是解决这两个问题的一个可能方案。纳尔逊·博阿滕正在用回收塑料制成的砖块建造房屋，而且成本只有混凝土建筑的一小部分。他的一居室公寓价格为1万1000美元，是用1万3400公斤塑料垃圾建造的。我们在生产塑料砖方面取得了进步，为非常低收入的加纳人建造了负担得起的住房。不是因为它很便宜，而是耐用性较差。它比我们现有的普通混凝土砖更坚固，因为这些砖可以承受积水的地方；它可以承受地震，而且不会燃烧。

Nelson mixes shredded plastic waste materials with sand under high temperatures to mold the inexpensive building bricks.The bricks have worked well for one-story buildings.But to lower costs and accommodate more people, he must find a way to build high-rise buildings.So, we thought of, Why dont we develop a different pillar corner bolt that can carry two three stories?So that is what we are working on now.The Ghana Standards Authority says tests show Nelsons building blocks meet quality standards.It passed the compression strength just as the ordinary sandcrete blocks also pass.So, the product is of good quality, and it can serve the same purpose as the traditional product.Nelson hopes his homes made from plastic waste will catch on with the Ghanaian public.Even better, perhaps forward-thinking luxury real estate developers will tend to using the plastic bricks when building their next high-rise.

纳尔逊将粉碎的塑料废料与高温下的沙子混合，以塑造廉价的建筑砖。这种砖在单层建筑中效果很好。但为了降低成本，容纳更多的人，他必须找到建造高层建筑的方法。所以，我们想，为什么我们不开发一种不同的柱角，可以承载两三层楼呢？这就是我们现在正在做的事情。加纳标准局表示，测试显示纳尔逊的砖符合质量标准。它通过了抗压强度，就像普通砂混凝土块一样通过。因此，该产品的质量很好，并且可以与传统产品实现相同的用途。纳尔逊希望他用塑料垃圾建造的房子能受到加纳公众的欢迎。更好的是，也许有远见的豪华房地产开发商在建造以后的高层建筑时会倾向于使用塑料砖。
