Recycling Waste Cigarette Butts into Innovative Products

Vocabulary flashcards summarizing key terms, concepts, and experimental methods from the lecture on producing innovative products by recycling waste cigarette butts.

Cigarette Butt

The discarded end of a smoked cigarette containing residual tobacco, filter paper, and filter; a major litter and pollution source.

Environmental Sustainability

Meeting present environmental needs without harming ecosystems or future generations; in this project, reducing cigarette-butt pollution.

Tobacco Fertilizer

Organic fertilizer created from the residual tobacco of recycled cigarette butts, evaluated for its effect on wheat seed growth.

Fly-Insect Repellent Paper

Hand-made paper infused with recycled tobacco that repels or kills stored-product insects such as moth larvae and rice weevils.

Amigurumi Fiber

Soft filling material obtained by combing and beating cigarette filter fibers, used to stuff crocheted (amigurumi) toys.

Filter Paper (Cigarette)

The paper encasing a cigarette’s filter section; recycled into insect-repellent paper sheets in the study.

Fiber Production (from Filters)

Mechanical combing and beating of sterilized cigarette filters to obtain reusable cellulose acetate fibers.

Germination Index (GI)

A numeric value indicating seed germination speed and uniformity, calculated from daily germination percentages.

Germination Rate (%)

The percentage of seeds that successfully germinate within a given period; used to compare fertilizer treatments.

Dry Matter Ratio (%)

The proportion of dry mass to fresh mass in plant tissue, reflecting moisture content and biomass accumulation.

Biomass

Total mass of living plant material; here, fresh mass minus dry mass of wheat sprouts.

Electrical Conductivity (EC)

Measurement (µS/cm) of a solution’s ability to conduct electricity, indicating salinity and nutrient levels in soil, water, or seed extracts.

pH Measurement

Assessment of acidity or alkalinity of soil, fertilizers, or water using a pH meter.

Autoclave Sterilization

Disinfection method using high-pressure steam at 121 °C for 15 minutes to sterilize collected cigarette butts.

Smoking Machine

Laboratory device that simulates human puffing patterns to generate standardized cigarette butts for experiments.

Wheat Sprout Length

Measured shoot length of germinating wheat seeds, used as a growth indicator under different fertilizers.

Rice Weevil (Sitophilus oryzae)

Grain-feeding beetle species used to test the insecticidal activity of recycled tobacco paper.

Dried Fruit Moth (Plodia interpunctella)

Stored-product pest whose larvae were exposed to insect-repellent papers to assess effectiveness.

Cigarette Components

The three recyclable parts of a cigarette butt: residual tobacco, filter paper, and filter medium.

Mineral Fertilizer

Inorganic fertilizer used as a comparison treatment; affected seed germination differently from tobacco fertilizer.

Sheep Manure

Organic fertilizer from ovine livestock employed as another comparative treatment in germination studies.

Recycling of Cigarette Butts

Process of converting waste cigarette materials into useful products like fertilizer, fiber, and insect-repellent paper.

Sustainable Product Development

Designing low-cost, eco-friendly goods that reduce pollution and benefit both humans and the environment.

Cigarette Filter Fiber

Cellulose acetate fibers extracted from cigarette filters and repurposed as stuffing material.

Mean Germination Time (MGT)

Average number of days required for seeds to germinate, calculated from cumulative germination data.

Humidity-Temperature Monitoring

Continuous tracking of environmental and soil moisture and temperature during seed germination experiments.

Biomass Calculation Formula

Biomass = Fresh Seed Mass − Dry Seed Mass; used to quantify plant growth.

Autoclave at 121 °C for 15 min

Specific sterilization condition applied to waste cigarette butts before material separation.
