And so we partnered with a local construction company to design, build and donate a tiny house.

因此，我们与当地一家建筑公司合作设计、建造并捐赠了一座小房子。

One of the solutions that we envisaged is that besides reducing ore, they would go  produce sand and gravel for local construction.

我们设想的解决方案之一是，除了减少矿石之外，他们还会生产用于当地建设的沙子和砾石。
