This is your point of view, we also bury our waste, and our radioactive waste, and you think it's safe? Are concrete forms eternal? Where does it crack over time? We will be confronted with this problem for millennia, your children and grandchildren will have to make with it, reconsolidated the concrete that protects our radioactive waste from the earth, but the groundwater is already affected by pollution, antibiotic waste, human intelligence? Is that putting chlorine in the water?
Carbon filter? In short, nature works for free, no borders, no politics, man has the financial aspect that makes it difficult for him to achieve easily what he wants, if we abolish money and borders, yes, I would be optimistic in research, but that is not the case, everything that man produces, pollutes,costs money, and energy, without this economic reality you can be optimistic, but this is not the case, e. g. cancer without the problem of finding money, we would progress much faster in research and solution, but this is not the case this economic reality makes man lose his time and energy,where it could progress much faster in the right direction, everything that man makes to try to do without natural resources is much more expensive, and is not economically viable, the electrical energy produced 100% by man is more expensive than extracting natural products,your synthetic essence costs 5 dollars a liter, without counting the energy price to do it, in short happy to have been able to exchange with you, it made me happy, it is always good to exchange our points of view, you with your optimism, and I the realism, go soon the friend

According to current technical knowledge, the production of synfuel is as CO2-emitting as refining, or even much more so when it is produced from coal. And the state of technology makes it a highly energy-intensive, and therefore expensive, mode of energy production.
However, the environmental performance of synthetic hydrocarbon production units can be significantly improved, and gain an advantage over conventional production from crude oil, through the implementation of carbon dioxide capture and storage (CCS). The cost of CCS is high in the more general case of coal-fired power plants, mainly because of the complexity of separating carbon dioxide from nitrogen in the air. In a synthetic fuel production unit, this cost is reduced by about 85%, because carbon dioxide is separated from nitrogen by the process itself.
The development of the BTL ("Biomass-To-Liquids") sector, a variant of biomass gasification, offers an alternative. The 2nd generation biofuels produced in this way use all plants, straws, stalks, waste, wood and not just seeds or fruits like current biofuels. But the BTL sector is still in its infancy. While many research projects are underway, no industrial unit is yet active. However, BTL pilot units are also expected to go into production in Germany in the near future. The BTL sector faces a major problem because the quantities of biomass required are enormous: it is therefore necessary to find a sufficient "deposit" and also to solve the logistical difficulties to transport all this biomass to the BTL plant.
The "CBTL", a combination of Coal-To-Liquids and BTL, offers particularly interesting environmental prospects. For example, the overall "well to car wheel" emission of diesel fuel in a unit fuelled by 85% coal and 15% biomass and equipped with a CCS would be 30% lower than that of diesel fuel conventionally produced from crude oil.
