The alarming rate of plastic waste generation in the Philippines serves as a powerful reminder that this problem is far more widespread than previously understood. Despite efforts to reduce plastic consumption, the rate of recycling post-consumption plastic packaging is a staggering 9%.
Single-use plastics have been in the spotlight for the past years because of its impact on our environment. It pollutes throughout its lifecycle beginning from extraction, refining, and ending in their disposal in the oceans and waterways, soil, and in the air we breathe through burning or incineration. In fact, it does not only impact our environment …
As awareness of the menace of plastic pollution grows, more than 127 countries have passed regulations to stem the production, distribution, use, and disposal of plastics. These include bans on certain types of plastics — most frequently, plastic bags — as well as taxes and user fees.1 z The European Union adopted a Single Use Plastics

In the Philippines and other parts of Southeast Asia, the problem was compounded by a new kind of plastic packaging that took flight in the 1980s — the sachet.
Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is …
China, Indonesia, the Philippines, Thailand and Vietnam (in that order) dump more plastic waste into the seas than the rest of the world combined. Take the Philippines, a country of 105 million. According to GAIA, a global alliance of green groups, in the Southeast Asian nation alone almost 57 million shopping bags are used.
Forests over limestone phenomena are geomorphologic features that result from the dissolution of a layer or layers of soluble bedrock, usually, carbonate rock. Limestone karsts cover 10% of the total land area of the Philippines and are notable for having high species endemism due to their unique flora and fauna (Fernando et al. 2008).

The concept of combining calcined clays and limestone to replace more clinker was first proposed by Antoni et al. [14], although calcined clays and limestone have long been used as pozzolanic materials and cement fillers [31, 32]. The key innovation of LC3 is the use of commonly available kaolinite clay, particularly the low-grade ones …
They have made a paper and plastic replacing substance on the basis of limestone, called Limex. Paper is made from wood pulp, which contributes to deforestation. Additionally, there is a lot of water necessary to make it. Plastic is made with petroleum, a non renewable resource.
