Indonesia uses plastic and rubber tires waste for road asphalt

Indonesia began to use plastic and rubber tires waste or a mixture of both for the asphalt material of the highway. The Research and Development Agency at the Ministry of Public Works and People's Housing of Indonesia uses plastic waste as a road asphalt material and the government agency also said it has mastered the technology of developing the same products using rubber waste.

"Our test results will be packed, especially our concerns, our experts use plastic and rubber. We have mastered the process," said the Head of Research and Development at the ministry, Danis Sumadilaga, in Jimbaran, Bali, on Saturday.

Asphalt-making technology using a mixture of plastic was first discovered by a chemical scientist from India, Rajagopalan Vasudevan, in 2015. Until now India has built a road along more than 25 thousand kilometers of asphalt made from plastic waste.

"We are standardizing this technology for implementation in Indonesia and have prepared modules for project implementers when building big or small roads," said Sumadilaga.

Indonesia has determined to conduct various researches to reduce plastic and rubber waste. President Joko Widodo at the G-20 meeting a few weeks ago has expressed Indonesia's commitment to reduce marine plastic waste by 70 percent by 2025.

To this day people often bury or burn plastic and rubber waste causing soil and air pollution. Wastes buried in the ground will eventually carry water and enter the river and then carried into the sea in the form of micro plastic. Indonesia uses plastic and rubber tires waste for road asphalt

On Saturday, the government tested a 700 meters of plastic and rubber asphalt at Udayana University in Denpasar, Bali. Sumadilaga said the utilization of plastic and rubber waste as asphalt is one solution for from various ways to solve garbage problem.

"Every 1 kilometer highway with a width of 7 meters requires a mixture of plastic and rubber waste or both 2.5 to 5 tons.Think if the scheme was done in Indonesia that has a network of roads thousands of kilometers," said Sumadilaga.

The amount of plastic waste in Indonesia in 2019 is estimated at 9.52 million tons or 14 percent of the total waste. Estimated use of 2.5-5 tons plastic waste per kilometer of highway will supply the needs of highway material along the 190,000 kilometers each year.

Asphalt produced by plastic and rubber waste material is more sticky when compared with conventional asphalt. The level of stability and resilience of the mixture increased 40 percent. The government has coordinated with the Indonesian Plastic Recycling Association in 16 major cities that will collect and sort waste.

"The initial stage is to educate the community," said Safri Burhanuddin, Deputy of the Coordination of Human Resource, Science and Technology and Maritime Culture of Indonesia.

Rolls-Royce plans for flying taxi service

Tinuku - Rolls-Royce Holdings plc has designed a propulsion system for flying taxi and is starting search for partners to help develop a project it hopes could take to the skies as soon as early next decade. British jet engine maker said on Sunday it had drawn up plans for an electric vertical take-off and landing (EVTOL) vehicle which could carry to five people at speeds of up 250 mph for approximately 500 miles.

The company joins a variety of companies racing to develop flying taxis, which could revolutionize the way people travel. Aviation and technology leaders are working to make electric-powered flying taxis a reality, including Airbus, U.S. ride- sharing firm Uber and a range of start-ups including one backed by Google co-founder Larry Page, called Kitty Hawk.

Rolls-Royce’s design will be showcased in digital form at the Farnborough Airshow, which starts on Monday. The company is looking for an airframer and a partner to provide aspects of the electrical system to help commerci…

Britain announced its first launch site for the space market

Tinuku - UK on Monday ran an important leap for the construction of the first vertical launch space launch site. The proposed space port at Sutherland in the north of Scotland has been awarded US$3.3 million in funding by the government-owned UK Space Agency to develop a ground-breaking launch site.

Government Business Secretary Greg Clark Monday launched the start of a Great British Space Age that will see vertically-launched space rockets and satellites take off from the new spaceport. UK Space Agency said it selected the Sutherland site because Scotland is the best place in Britain to reach highly sought-after satellite orbits with vertically launched rockets.

The initial funding will go to Scotland's Highlands and Islands Enterprise agency to develop the Sutherland site which will use a combination of proven and innovative rocket technologies to pave the way for a world-leading spaceflight market.

The UK Space Agency is also making available a new 2.65 million U.S. dollar fund…
