hlieberman: It's a concrete that: 1) breaks down in water in a day(!), and 2) has a "5 times
higher impact on human health and 3 times higher impact on eco-toxicity as compared to concrete.".<p>Cool research, but I'll pass on using it.

hlieberman: 它；这是一种混凝土：1）在水中一天内分解（！），2）有一个“；5次与混凝土相比，对人类健康的影响更大，对生态毒性的影响高3倍&“<p> 很酷的研究，但我；我会继续使用它。

szvsw: Interesting. The degradation in wet conditions seems like a major challenge to solve.<p>I initially was skeptical of the utility when I saw the mention of heating requirements, but the temperatures aren’t that extreme, and seem very reasonably achieved with electrified energy sources (which in turn can easily be supplied via renewables).<p>Being able to produce concrete without the emissions involved with the production of portland cement is a major goal of decarbonizing the building stock, so it’s always good to see new lines of research in this front, even if still in the germinal stages!<p>ARPA-E Hestia has some cool alternatives (a bit further along in research stages) for those interested:<p><a href="https://arpa-e.energy.gov/technologies/programs/hestia" rel="nofollow">https://arpa-e.energy.gov/technologies/programs/hestia</a>

szvsw: 有趣。潮湿条件下的降解似乎是一个需要解决的主要挑战<p> 当我看到提到供暖要求时，我最初对这家公用事业公司持怀疑态度，但温度并没有那么极端，用电气化能源（反过来可以很容易地通过可再生能源供应）似乎非常合理<p> 能够生产混凝土而不产生硅酸盐水泥生产过程中的排放是建筑材料脱碳的主要目标，因此，即使仍处于萌芽阶段，在这方面看到新的研究成果总是很好的<p> ARPA-E Hestia为感兴趣的人提供了一些很酷的替代方案（在研究阶段还有一点进展）：<p><a href=“https:”ARPA-E.energy.gov“technologies”“programs”“Hestia”rel=“nofollow”>https:”&#x2F；arpa-e.energy.gov；技术；程序；赫斯蒂亚</a>

zouhair: Stop using food for anything else than food, people. We don't have enough arable land to waste on this stuff.

zouhair: 人们，别再把食物当食物了。我们不；我没有足够的耕地浪费在这些东西上。

danans: A big possible issue with this is that cornstarch (at least the way it's currently produced) has the same carbon footprint as portland cement, which it replaces in this process.<p><a href="https://apps.carboncloud.com/climatehub/product-reports/id/75110207553#:~:text=”Corn starch” currently has a,of 0.96 kg CO₂e%2Fkg" rel="nofollow">https://apps.carboncloud.com/climatehub/product-reports/id/7...</a>.

danans: 一个可能的大问题是，玉米淀粉（至少是目前生产的方式）的碳足迹与波特兰水泥相同，在这个过程中它会取代波特兰水泥<p> <a href=“https:&#x2F；apps.carbocloud.com&#x2G；climatehub&#x2C；产品报告&#x2D；75110207553#：~：text=%E2%80%9DCorn%20s%E2%80%9D%20s%20s%20has%20a，%200.96%20kg%20CO%E2%82e%2Fkg”rel=“nofollow”>https:&#x2F；apps.carbocloud.com；气候中心&#x2F；产品报告；id&#x2F；7…</a>。

andai: Does the polymerization prevent biodegradation (e.g. digestion by fungus)<p>I don't think I have access to the full paper, but it is described as biodegradable, which seems to be the opposite of what you'd want your house to be made of?

andai: 聚合反应是否会阻止生物降解（例如真菌的消化）；我想我无法获得整篇论文，但它被描述为可生物降解的，这似乎与你的说法相反；我想让你的房子变成这样吗？
