California is an epicenter for the growth of a new class of cement that is used to build homes, factories, hotels and even schools.

But it is also a state that is also home to the largest cement waste and pollution problem in the US.

And the answer to that has been largely hidden from the public.

Cement is a byproduct of cement factories.

Cement is an extremely heavy and expensive ingredient that has to be mixed with cement to make cement.

It is often combined with other chemicals and chemicals are toxic.

And once mixed, cement can be extremely flammable.

Al Jazeera spoke to people who have seen it on their hands and feet, to people whose homes have been built with cement, to those who work in the industry and to environmental activists who are fighting the industry.

We wanted to talk to the people who live in these communities and try and get a better sense of how cement is being used and the impacts that it has on people’s lives and on their communities.

The cement industry in California, which is estimated to be worth more than $1.6bn (£739m) a year, has a history of pollution and waste.

In 2014, a toxic chemical leak at a cement plant in the city of Culver City was blamed on the toxic fumes of the chemicals used to make the cement.

The leak was reported by the California Air Resources Board, which was later shut down.

In 2015, an environmental group found the chemicals in a landfill in the Los Angeles area.

In January 2016, a fire at a Cargill cement plant burned more than 200 homes and a plant in Ventura County.

In January 2018, more than 100 people were injured in a fire that broke out at a company in San Francisco, a smog-inducing event that authorities blamed on fumes from the chemical cement used to manufacture cement.

In 2016, California became the first US state to impose an emergency carbon tax, which requires companies to pay a 1.5% surcharge on all greenhouse gas emissions.

In 2020, California imposed a $50m annual fee on cement producers.

Cemex, the company that makes the cement used in the cement industry, says it is working with regulators to reduce the pollution.

But many residents say the industry has made a huge profit from the pollution it causes, and that it is not paying enough attention to the environment.

“The cement that’s being used in these buildings and the cement that goes into the cement factory and the factory itself is an incredible waste,” said Stephanie Jones, an activist and the mother of one of the residents in our study.

“There’s not a single cement product that is produced in California that isn’t a huge contributor to the soil that we use for our food, our water and for our homes.”

Jones says it’s been difficult to get her daughter to move out of the city.

But she says she has seen the community get used to the smell of the cement factories and has seen them become less toxic.

“People have stopped and started to pay attention to it, to the health of the soil, the air, and they’ve started to realize that they can do something about it,” Jones said.

Clemex spokesperson Melissa Hwang says the company is aware of the impact cement is having on the environment and is committed to doing everything in its power to reduce and manage the impact of its products.

“We do have plans to develop new technologies to reduce carbon footprint, reduce soil contamination and improve the quality of life in communities that have been impacted by these facilities,” Hwang said.

She says the emissions that are released are mostly methane and nitrous oxide, but the company also works with governments to limit emissions from their factories.

“For example, we work with the California Public Utilities Commission, the state Department of Agriculture and the California Department of Food and Agriculture to develop a protocol to reduce methane emissions at the California cement plant,” Hwan said.

The problem with cement wasteThe cement waste in California is a big problem.

A 2016 report by the Environmental Working Group found that the industry was responsible for nearly a quarter of the emissions in the state’s waterways and air.

The state is also notorious for the use of a chemical called caustic soda.

It has been linked to serious health problems, including cancer and birth defects.

In 2017, the US Environmental Protection Agency (EPA) approved a ban on caustics in the country’s largest cement factories, in an effort to reduce CO2 emissions.

But that ban does not apply to the cement waste at Cargills factories.

The company has defended the decision by saying it has been following a rigorous, rigorous, comprehensive, long-term plan for reducing the emissions of its cement products.

The company says it does have plans in place to reduce its cement waste.

But environmental activists say the plans have not been followed.

“If you’re not going to do it now, you’re
