Agricultural waste comes from farms, poultry houses, and slaughterhouses. It includes biological, solid, and hazardous materials. If not properly disposed of, agricultural waste can pollute the land, air, water and harm biodiversity through toxins. Effective waste management is needed and includes reducing, reusing, recycling, and reeducating practices. Treatment plants can process waste to produce biogas while minimizing harmful impacts on the environment. The goal of waste management is to work towards zero waste.Unit-IV-Environmental Pollution.ppt

Pollution is harming the environment and human health in India. Rapid population growth and industrialization have led to problems like industrial pollution, soil erosion, deforestation, and land degradation. This pollution comes from sources like sewage, household garbage, industrial waste, and agricultural runoff. It is causing diseases, harming aquatic life, and depleting fresh water sources. India has been ranked as one of the most environmentally hazardous countries due to these issues. Solutions require preventing pollution, conserving resources, and treating wastes and emissions.Solid waste management

Solid waste includes organic and inorganic materials that are discarded because they have lost their value to the original user. Solid waste comes from residential, commercial, institutional, and other sources. It can be classified based on its source and type. Improper management of solid waste leads to air and water pollution and health issues. A solid waste management system includes generation, storage, collection, processing, and disposal. Processing techniques include incineration, composting, and landfilling. Proper waste management following rules of reduce, reuse, and recycle is needed.Water pollution caused by toxic substances

Toxic substances can pollute water through various means such as discharge of industrial and commercial wastewater and waste, release of contaminants in surface runoff from urban and agricultural areas, waste disposal and groundwater leaching, and eutrophication. Other sources of water pollution include agriculture, land clearing, and littering. Some ways to help prevent water pollution are to conserve water, be careful about what is poured down drains, use environmentally friendly household products, limit overuse of pesticides and fertilizers, plant gardens to absorb runoff, and properly dispose of litter.Pollution types

Biodiversity loss is occurring globally at an unprecedented rate due to human activities. Habitat loss, invasive species, over-exploitation, pollution, and climate change are the main drivers of biodiversity loss. Habitat loss, such as the destruction of rainforests for agriculture, removes species' homes. Invasive species disrupt ecosystems when introduced. Over-exploitation from activities like poaching has endangered many species. Pollution degrades habitats. And climate change is causing shifts that prevent many species from adapting quickly enough. This rapid biodiversity loss poses serious risks to human welfare and Earth's life support systems.Green building and green city PPT.pptx

Surveying is the science of determining the positions of points on or near the earth's surface. It involves decision making, fieldwork, data processing, mapping, and stakeout. The primary objectives of surveying are to prepare plans for estates, buildings, infrastructure, and to measure areas. Plane surveying considers the earth's surface flat over small areas, while geodetic surveying accounts for curvature over large areas. Distance is typically measured using tapes or chains, and errors are corrected for tape length and temperature.Recently uploaded (20)
DUST SUPPRESSING CHEMICALS : MECHANISM APPLICATION & MARKET TRENDS
DUST SUPPRESSING CHEMICALS : MECHANISM APPLICATION & MARKET TRENDSJanapriya Roy
油
Dust pollution is a critical environmental and occupational concern, especially in industries such as mining, construction, and manufacturing. The adverse effects of airborne dust particles include health hazards, decreased machinery efficiency, and environmental degradation. Dust-suppressing chemicals provide an effective means to control dust dispersion by binding particles, retaining moisture, or forming protective crusts. This paper explores the mechanisms, working principles, market trends, and future directions of dust suppression technology. Advancements in eco-friendly formulations, nanotechnology applications, and automated dispensing systems are expected to drive the industry's evolution. The market for dust suppressants is expanding due to regulatory mandates and increasing awareness of environmental and occupational health standards. The analysis highlights the major application areas where dust-suppressing chemicals are essential for maintaining operational efficiency and environmental sustainability.
Dust-suppressing chemicals function by altering the surface tension of dust particles and binding them together, thereby reducing their ability to become airborne. These chemicals can work through different mechanisms, including:

Breakout session on Tuesday, February 11, at 2:45 p.m.
H2Ohio addresses urgent water quality problems, such as algal blooms from agricultural runoff. Starting in 2020, H2Ohio has encountered challenges in contract management and efficient program delivery. With more than $60 million in annual support, the initiative works with local SWCDs to implement BMPs across 1.8 million acres, which creates opportunity and trials along the way.

Breakout session on Wednesday, February 12, at 9:00 a.m.
The ICCD Growing for Good Health Initiative was launched with a goal of inspiring and empowering our older adult population to prioritize nutrition and health through the benefits of growing and consuming fresh produce. Participants in this workshop will learn how the ICCD was able to utilize non-traditional partnerships to implement a unique specialty crops program to reach an undeserved population in Indiana County.
