There is no better time for projects that deal with renewable energy (even though burning waste is not directly a renewable energy) than today. Projects like 4New are really tackling important problems: Waste-treatment and electrical power supply. So I wouldn't say at all that the right time hasn't come yet.
The bottom line here is Energy, when is the right time to have the right type of energy? I doubt if there is ever any right or wrong time, we are talking about what really affects us as a people and our every activities
I see this as absolutely the right time for 4NEW. They are going to establish themselves as they waste to energy provider in the crypto world.
