Researchers from James Cook University in Australia have created a type of concrete that's reinforced by plastic waste, rather than steel. The technique, which is a first in Australia, will greatly reduce the environmental impact of concrete, and we can't help but wonder why we're not doing this already.
sir,i want to know the mix design of Plastic Concrete: Building Bricks Made From Landfill Waste. Anonymous June 10, 2010 at 10:18 am I WANT TO A PROJECT IN PLASTIC BASE .
Most of waste materials produced by demolished structures disposed off by dumping them as land fill. Dumping of wastes on land is causing shortage of dumping place in urban areas. Therefore, it is necessary to start recycling and re-use of demolition concrete waste to save environment, cost and energy.
For working with concrete in hot weather, our CryoCrete™ Concrete Cooling Systems use liquid nitrogen as an alternative to traditional cooling methods. Manufacturing & Metal Fabrication Nitrogen is used as an effective way to prevent oxidation and provides a safe, inert atmosphere that “sweeps” off gases produced by furnaces.

Find out what methods are used in what applications and why. The chemical process industries (CPI) employ nitrogen — as a gas or liquid — in a wide range of applications (1, 2). Gaseous nitrogen (GAN) can inert vessels and purge lines to eliminate explosion hazards and prevent undesired oxidation reactions that can reduce product quality.
Nitrogen's low boiling point and non-toxic properties make it an economical choice for recycling tyres through cryopulverisation. In this process, liquid nitrogen serves as a freezing agent and embrittles shredded tyre scrap so that it can be easily ground into crumb rubber.
Nov 15, 2014 · What Is Recycle aggregate concrete 6. Characteristics of recycle aggregate concrete Recycle aggregate concrete has a Crushed sound and clean waste concrete of at least 95% by weight of concrete with typical total contamination lower than 1% of the bulk mass Class 1A RCA is a well graded RCA with no more than 0.5% brick content 7.
Human hair is considered a waste material in most parts of the world and its accumulation in waste streams causes many environmental problems; however, it has many known uses. Preventing waste of such a material requires both addressing the problems in the current usage and developing its utilization systems at locations where they are missing. With focus on developing systematic utilization ...
• If the fertilizer is liquid and does not contain pesticides or more than 25% Nitrogen, it may be poured down the drain (only if you are connected to a waste water line). • If 25% Nitrogen or more, bring to the WLSSD Household Hazardous Waste Facility.

Actually the rubber powder production from used tyres for recycle may be achieved by means of mechanical, cryomechanical with liquid nitrogen and cryomechanical with air disintegration. In this paper a new technology concerning the air cryogenic disintegration of used tyres will be examined considering the obtained products (quality and quantity) and a cost - benefit analysis.

The liquid nitrogen evaporates and then enters as a cold gas in the first tube bundle of the cryo condensator. Here it transfers its cold to the exhaust gas flowing from below and warms up. The now warm nitrogen is now fed back to the evaporator and serves as a heat source for the evaporation of nitrogen.

Wastewater treatment plants are designed to convert liquid wastes into an acceptable final effluent and to dispose of solids removed or generated during the process. In most cases, treatment is required for both suspended and dissolved contaminants.
Simple Waste Water Treatment For Concrete Producers. Many concrete production plants generate large amounts of high pH waste water. This waste or process water also contains a high level of dissolved and suspended solids. The waste water comes from rinsing the drums of the mixer trucks after returning from a delivery and from truck washing on ...
