Reduce the concrete waste

For the abandoned fresh concrete in construction site, normally, it is dumped on site and griped to the landfill. It is obviously a waste of energy, material and cost in the process to produce, transport and dump it. Some foreman may give 1-200 HKD$ to the driver and illegally let the driver dump to other country part area, rural area for the villager to place in a car parting area,or fill the pond in rural area. 

I think there is a better way to improve it. Such as the government should make some precast mould in the construction project. So that we can make use of the abandoned fresh concrete. Like precast chair, breach... whatever creative product.

Or the client could open a WhatsApp group. A works supervisor in different construction site should show their contact in this WhatsApp group. They take responsibility to publicize the concrete pouring date and quantity of abandoned fresh concrete in the WhatsApp group. So that citizens can contact the driver to buy the “waste”.
