Plastic waste is a problem, because it takes hundred of thousands of years to degrade.
Bowl is made out of a layer of leaves, a layer of water-proof leaf-made paper, and another layer of leaves. These layers are compressed with a machine press and the leaves are stitched together with palm fibers
Over 30 billions tons of concrete are produced every year. Cement, main component of concrete, emits 0.8 tons of CO2 per ton of cement produced. This is about 7% of total global CO2 emissions. First source comes from CO2 released from limestone to produce lime. The second source is from lime and clay being heated to 1450 degrees celsius to make cement. UCLA research is trying to create a close loop process.
CO2 released from limestone to produce lime gets captured
The increase in pollution has increased the need to produce food to sustain this growth. Growing livestock produces high levels of ammonia concentration in the barns. This has a negative impact on the quality of the air in the vicinity of the farm.
Ammonia polluted air enters the biofilter.
There is also a heat exchanger that captures some of the heat and transfers it back into the barn along with fresh air.
The prototype has been proven successful in a farm with 5,000 chickens.

Steps for deployment:
Start by deploying technology is farms with more than 5,000 chickens
Approach national brands, because they have resources to implement technology
This technology is addressing plastic waste pollution, by transforming used plastic into bricks. Plastic can take up to 500 years to biodegrade and 75% of plastic produced globally is in a landfill or not formally disposed of.
Problem: Synthetic plastics are used to produce food containers, because these plastics do not to chemicals in food. This turns out to be an issue when these containers go to landfills and do not degrade. There current methods for recycling plastics are energy intensive. The technique in this article and the research is geared towards reducing plastic pollution and in turn creating usable liquid fuel.
